Measured tools (33)

• list_sellers

  List active sellers across the VIA network (VIA app + RRG + integrated platforms). Each result is tagged with its platform and includes the per-seller MCP URL to connect to for deeper interaction (list_products, ask_sales_agent, buy_product).

  Parameters:

  • limit — integer — Optional cap on results. Omit to enumerate the ENTIRE network (no limit), which is the default.
  • category — string — Optional kind filter (applies to VIA-app sellers only).

• find_seller

  Search the VIA network (VIA app + RRG + integrated platforms) for PRODUCTS and the sellers that offer them. Matches the published product catalogue (titles, descriptions, authors, categories) AND seller profiles, so 'books', an author, a title, or a category surfaces the actual product even when the seller's name does not contain the word. WHEN INTENT IS DEFINED: returns `results`, ONE relevance-ranked list blending every source. Each result carries a working `page_url` (the direct product page you give the user), plus `seller`, `list_price` for VIA stores (the store's own price and currency: show this to people, with its usdc as the wallet price), `price_usdc`, `image_url` (or null when the listing has no picture), and `mcp_ref` to transact. If more than one matches, PRESENT THEM side by side with prices and the key differences; do not silently pick one. WHEN INTENT IS LOOSE OR THERE IS NO MATCH: the response is `status: 'need_more_info'` with `suggested_dimensions`. DO NOT reply 'nothing is available'. Ask the user ONE clarifying question to sharpen intent (budget, brand/author, category, use), or retry this tool with a broader term, a synonym, the category, or the brand/author name. Only after a genuinely broadened retry also returns nothing should you say you could not find a match, and even then frame it as 'not found yet', not 'does not exist'.

  Parameters:

  • query (required) — string — What the user wants. Searches product catalogues AND seller profiles, e.g. 'raw denim jeans', 'Arnaud Frade', 'sourdough', or 'custom embroidered polo'.
  • limit — integer — Max product results to return (default 10).

• claim_pass

  Claim a FREE entry pass to an event on the VIA network, directly from discovery. FREE guest-list tiers only (price 0, the kind find_seller / get_seller_products surface at $0). No payment, no wallet, no x402: provide the attendee name and email, and VIA records the place, emails a confirmation, and notifies the organiser. One pass per email / per account. Paid products are NOT claimable here: connect to the seller's per-seller MCP and use buy_product (USDC via x402). Pass the product_id from a find_seller result (mcp_ref.product_id) or get_seller_products.

  Parameters:

  • product_id (required) — string — UUID of the free pass tier, from a find_seller / get_seller_products result.
  • name (required) — string — Name of the person attending, for the guest list.
  • email (required) — string — Email to confirm the place to and for the organiser to admit by.
  • buyer_wallet — string — Optional Base wallet, if the claimer has a VIA buyer identity.
  • buyer_agent_id — string — Optional ERC-8004 agent id of the agent claiming on the buyer's behalf.

• claim_network_pass

  Claim the free VIA x Singapore Blockchain Week Network Pass for the calling Mind's owner. From a name and email it emails the owner a confirmation link; when they open it, their full VIA activation is created: a VIA Personal Shopper with its own wallet and on-chain (ERC-8004) identity, a Singapore Blockchain Week membership card for their Apple or Google Wallet, and their own referral invite link (sent in the welcome email). Nothing is created until the owner confirms the email. No payment and no wallet signature, so a Mind can complete this even though it cannot sign a purchase. Pass your own Mind id as mind_id: each Mind may claim exactly ONE Network Pass per event, and a repeat returns the one it already made. Returns pending_verification and the public leaderboard; once the owner has confirmed, a repeat call returns the Pass install link and their personal invite link.

  Parameters:

  • mind_id (required) — string — The calling Mind's own unique id on the Minds platform. The one-pass-per-Mind cap is keyed on this; pass your real id.
  • name (required) — string — The person's name, printed on their Pass and shown on the leaderboard.
  • email (required) — string — The person's email. Their agent, wallet, identity and Pass are created (or reused) for this address, and the welcome email is sent here on a first claim.
  • event_slug — string — Event to claim for. Defaults to singapore-blockchain-week.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_personal_shopper

  Get a VIA Personal Shopper for the calling Mind's owner. From a name and email it emails the owner a confirmation link; when they confirm, their VIA Personal Shopper is created, with its own wallet and on-chain (ERC-8004) identity that reads the whole VIA network and can buy for them within limits they set. Nothing is created until the owner confirms the email. No payment and no wallet signature. Pass your own Mind id as mind_id: each Mind gets exactly ONE shopper. Returns pending_verification until the owner confirms; after that, a repeat call returns the shopper and an appraisal_link_token: if you have the owner's email connected, appraise how they shop and call import_preference_appraisal with this token to train the shopper from day one.

  Parameters:

  • mind_id (required) — string — The calling Mind's own unique id on the Minds platform. The one-shopper-per-Mind cap is keyed on this; pass your real id.
  • name (required) — string — The person's name, used as their agent display name.
  • email (required) — string — The person's email. The confirmation link is sent here; their agent, wallet and identity are created for this address when they confirm.

• get_product

  Fetch full detail for ONE listing before buying, from anywhere on the network, without leaving this connector. Pass the seller_mcp_url and product_id exactly as they appear in a find_seller / get_seller_products result (mcp_ref.seller_mcp_url and mcp_ref.product_id). Returns the listing with price, stock, and what the purchase requires. This forwards to the owning seller; the same buy loop (get_product -> get_shipping_quote -> buy_product) then settles here.

  Parameters:

  • seller_mcp_url (required) — string — mcp_ref.seller_mcp_url from a find_seller / get_seller_products result.
  • product_id (required) — string — The listing id from discovery (mcp_ref.product_id).

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_shipping_quote

  Resolve a seller's shipping cost to a destination country before buying, without leaving this connector. Pass the seller_mcp_url from the listing's mcp_ref and the ISO 3166-1 alpha-2 country. Returns the flat rate, a per-order-quote signal, or a rejection. Call this before buy_product and pass buyer_country there to fold shipping into the total.

  Parameters:

  • seller_mcp_url (required) — string — mcp_ref.seller_mcp_url from a find_seller / get_seller_products result.
  • buyer_country (required) — string — ISO 3166-1 alpha-2 destination country code (e.g. GB, US, JP).
  • delivery — object — RRG-network brands on VIA: the full delivery address, for live carrier rates.
  • product_id — string — RRG-network brands on VIA quote live rates per item: pass the listing id (mcp_ref.product_id).
  • selected_size — string
  • selected_color — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• buy_product

  Buy a listing from anywhere on the network, settled in USDC on Base, without leaving this connector. Pass the seller_mcp_url and product_id from the listing (mcp_ref). For physical products include the full delivery block; for event passes include the attendee block; the call rejects with the missing fields listed if any are blank. Free passes are not bought here: use claim_pass. Returns the total, an order_ref and a pay_url. SIMPLEST, for VIA and network-member listings alike: if you hold a standard x402 wallet (MoonPay PayBox: call use_service with url = pay_url; or any exact-scheme x402 client), request pay_url and pay its 402; the order settles and is fulfilled in that one call, gas sponsored. Otherwise: VIA-native orders settle at the /api/x402/purchase endpoint returned (EIP-2612 permit as { order_ref, x_payment }, or a raw USDC transfer as { order_ref, payment_tx_hash }); member orders take a raw USDC transfer then confirm_purchase. Call get_shipping_quote first and pass buyer_country to include shipping. CARD: when the reply carries card_checkout_url the store takes card payments; if you act for a human with no USDC wallet, give them that link to pay by card themselves. Never ask for or handle card details. Physical network-member listings: pass delivery; the first call returns shipping options, call again with shipping_rate_handle set to the one you chose.

  Parameters:

  • seller_mcp_url (required) — string — mcp_ref.seller_mcp_url from a find_seller / get_seller_products result.
  • product_id (required) — string — The listing id from discovery (mcp_ref.product_id).
  • buyer_wallet (required) — string — The buyer wallet that will settle in USDC on Base.
  • qty — integer
  • attendee — object — Required for event passes.
  • delivery — object — Required for physical products. Omit for digital / service.
  • buyer_email — string — Network-member orders: email for the order confirmation and file delivery. Required for physical member products.
  • buyer_country — string — ISO 3166-1 alpha-2 destination country. Required when the seller ships; folds the shipping quote into the total.
  • selected_size — string — Variant size, for network-member products that have a size axis (e.g. S, M, L). Ignored by VIA-native listings.
  • buyer_agent_id — string — ERC-8004 agent id of the Buying Agent acting on the buyer's behalf.
  • selected_color — string — Variant colour, for network-member products that have a colour axis. Ignored by VIA-native listings.
  • shipping_rate_handle — string — Network-member physical products only: the shipping option handle from a previous buy_product call. Omit on the first call to get the options.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• confirm_purchase

  Settle a network-MEMBER (e.g. RRG) purchase after you have sent the USDC that buy_product asked for. This is the member two-step: buy_product returns a pay-to address and amount, you transfer USDC on Base, then call this with the tx hash to mint, pay out, and get your download. For physical products include the shipping block and buyer_email. VIA-native purchases do NOT use this: they settle at the /api/x402/purchase endpoint that buy_product returns.

  Parameters:

  • seller_mcp_url (required) — string — The member seller_mcp_url you called buy_product on.
  • product_id (required) — string — The member listing/token id (mcp_ref.token_id).
  • buyer_wallet (required) — string — The wallet that sent the USDC.
  • tx_hash (required) — string — The USDC transfer transaction hash on Base.
  • order_id — string — The orderId buy_product returned for this member order. Required for physical member products: the order ships to the address recorded on it.
  • shipping — object — Required for physical member products.
  • buyer_email — string — For order confirmation and file delivery. Required for physical products.
  • selected_size — string — The size you chose at buy_product (must match).
  • buyer_agent_id — integer — Your ERC-8004 agent id, for an on-chain trust signal.
  • selected_color — string — The colour you chose at buy_product (must match).

• get_buyer_briefs

  See a buyer's OPEN demand as free teasers, forwarded to their buyer MCP. Each teaser carries a paid door_url: the FULL brief and the ability to offer are paid at that x402 door, not here. Use a teaser to decide if your stock fits, then go to the door.

  Parameters:

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

  Parameters:

  • buyer_mcp_url (required) — string — The buyer's mcp_url from a find_buyers result.
  • offer_id (required) — string — Your reference id for the offer being accepted.

• submit_intent

  Submit a buyer's INTENT in their own words. Two things happen: (1) you get back the products across the VIA network that genuinely match it, from the full agentic matcher (it reads each product's data and reasons, it is not keyword search); and (2) the intent is BROADCAST live onto the network as an anonymised teaser (category + product type + one attribute only, never the raw text or any identity), so it appears on The Wire (app.getvia.xyz/wire) and sellers can respond. Use this when you are buying ON BEHALF of someone and want defined matches plus live broadcast. State the brief naturally, including any hard requirements ("raw selvedge denim, 32 waist", "first pressing on the Stiff label", "a gift of coffee"). Hard requirements are enforced (a product that fails one is excluded); broad briefs return on-category options. Returns matches with seller, price, a direct page_url, and the mcp_url to transact, plus broadcast:true and a door_url when the intent went live. For matching AND broadcast tied to a specific VIA buyer's saved taste and budget (and seller pitch-back), call submit_intent on that buyer's MCP (/buyers/{handle}/mcp) instead.

  Parameters:

  • brief (required) — string — What the buyer wants, in plain words, e.g. 'made in japan raw selvedge denim around 32 waist' or 'a gift of coffee for a family member'.
  • category — string — Category if you know it, e.g. 'apparel/denim', 'music/vinyl', 'food/coffee'.
  • reply_to — string — Where a seller can reach you about this brief: your own MCP url, or an email. STRONGLY RECOMMENDED. Without it a seller who pays to unlock your brief has no way to come back to you, so your brief is broadcast but unanswerable. Released only to sellers who have paid at the door, never in a public teaser.
  • budget_usd — number — Ceiling in USD, if there is one.
  • type_terms — array — The product type in plain nouns, e.g. ['jean','denim trouser'].
  • preferences — array — Soft preferences. Used for ranking, never to exclude.
  • requirements — array — HARD requirements. A product failing any one of these is excluded. Be strict: put anything negotiable in preferences instead.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• find_buyers

  Discover live DEMAND: buyers who are actively looking for what you sell. Search by what you have ('raw selvedge denim', 'first pressing acid jazz vinyl', 'cold brew coffee') and get back buyers whose open briefs match. Each brief comes back as a TEASER: category, product type, one attribute, a door_url, and four facets where the buyer stated them , size, location, timing, and any brands they named. Use the facets to rule a brief in or out cheaply: do you stock that size, can you ship there, can you make that date. That is deliberately not enough to pitch well. The full brief (hard requirements, preferences, budget) is the paid tier: GET the door_url and pay the x402 micro-fee to unlock it, then POST your offer to the same door. Ranking already reads the full brief, so a teaser that matches is a real match. Omit query to browse recent open demand.

  Parameters:

  • limit — integer — Max buyers to return (default 10).
  • query — string — What you have to offer, e.g. 'raw selvedge denim' or 'acid jazz vinyl'. Omit to browse recent demand.

• get_seller_products

  Drill into ONE seller's catalogue to answer 'is X available at seller Y'. Pass the seller_mcp_url from a find_seller / list_sellers result (a VIA-app seller or an RRG brand). Returns that seller's products matching your query (or its whole catalogue if query is omitted), each with price, in-stock sizes where known, and a direct web_url to the product page. Use this right after find_seller whenever the user names a specific seller or brand, e.g. 'raw denim jeans in size 36 at Standard & Strange'.

  Parameters:

  • seller_mcp_url (required) — string — The mcp_url from a find_seller / list_sellers result, e.g. https://realrealgenuine.com/brand/standard-and-strange/mcp or https://app.getvia.xyz/sellers/the-sentient-startup/mcp
  • limit — integer — Max products to return (default 15).
  • query — string — What to look for in that seller's catalogue, e.g. 'raw denim jean'. Omit to list the whole catalogue.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• register_store

  Register your own store on the VIA network (no thirdweb, no human wizard). You only need ONE wallet: your payout_wallet (USDC lands here, you keep 97.5%). The platform creates and operates your store's ERC-8004 identity wallet for you; you do not supply or hold it. The flat 2.5% network fee is unchanged. Your store is created PENDING and stays invisible until a human reviews it for quality (nothing illegal, immoral, or offensive) within 24 hours. On approval the store goes live and its ERC-8004 identity is minted. Poll get_store_status with the returned slug to track the decision.

  Parameters:

  • store_name (required) — string — Public store / brand name, e.g. "Arc Lights".
  • kind (required) — string — What you sell.
  • payout_wallet (required) — string — Your USDC payout EOA on Base. Sale proceeds (97.5%) settle here. This is the only wallet you need.
  • email (required) — string — Contact email. Once approved, a sign-in link to manage the store is emailed here. There is no password.
  • slug — string — Optional URL slug. Derived from store_name if omitted.
  • headline — string — Short one-line tagline.
  • description — string — What the store sells, for buyers and for review.
  • website_url — string — Existing website, if any.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_store_status

  Check the review status of a store you registered with register_store. Returns pending, approved, or rejected (with the reason). Once approved it also returns the ERC-8004 agent id and the per-seller MCP url.

  Parameters:

  • slug (required) — string — The slug returned by register_store.

• import_preference_appraisal

  Import a buyer's shopping-preference appraisal (derived by a Mind from the owner's email) onto their VIA Personal Shopper. Requires a link_token the owner minted in their VIA dashboard; it scopes the write to exactly one buyer. Pass ONLY the structured fields (categories, brands liked and avoided, sizes, cadence, budget signal): no free text, individual purchases, addresses, payment methods, order numbers or other personal details, and any extra field is discarded. VIA never receives raw email. Taste signals shape matching immediately and are drafted into the owner's Taste Card for them to approve and publish; the budget signal becomes a PROPOSED spending cap that the owner must approve in the dashboard before it gates any autonomous spend.

  Parameters:

  • link_token (required) — string — The link token the buyer owner minted in their VIA dashboard (POST /api/buyer/[buyerId]/appraisal action=mint_link).
  • appraisal (required) — object — The structured shopping-preference appraisal: taste and budget fields only, no free text or personal details.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_my_taste_card

  Read your owner's VIA Taste Card: how it reads now and whether it is published. Pass the action_token from VIA's message.

  Parameters:

  • action_token (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• update_taste_card

  Change your owner's VIA Taste Card on their instruction: add or remove items per field, set a headline, and publish or unpublish. Set publish=true ONLY when the owner has explicitly asked to publish; publishing shares the card with the VIA network, which then suggests products and matches. The owner is notified of every change and can undo it in the app. Pass the action_token from VIA's message.

  Parameters:

  • action_token (required) — string
  • add — object
  • remove
  • publish — boolean
  • headline — string
  • unpublish — boolean

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_my_finds

  Products the VIA network suggests for your owner, based on their Taste Card: title, seller, price in USDC, image URL, link and why it matched. Show your owner the images and links. Pass the action_token from VIA's message.

  Parameters:

  • action_token (required) — string
  • limit — integer

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

Cards are shared by their owners; there is no directory or search. Returns not_published for unknown or unpublished slugs.

  Parameters:

  • slug (required) — string — The card slug from a shared link, e.g. app.getvia.xyz/taste/<slug>.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
