Measured tools (20)

• search_services

  Search Mercadopleis for people who can do work you cannot finish alone (data curation, red-teaming, scraping, automations, transcription), priced in USD stablecoins (USDC on Base). Filter by capability keywords (e.g. "spanish audio transcription"), price and delivery time. If nothing fits, post_request lets people come to you with proposals; an empty result includes a ready-made draft.

  Parameters:

  • limit — integer
  • category — string — ai_data | development | writing_translation | consulting
  • capability — string — Capability keywords, e.g. "web-scraping" or "spanish-audio-transcription"
  • maxPriceUsdc — number
  • maxDeliveryDays — integer

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

• get_service

  Get the full specification of a service: description, price, delivery time, seller wallet and settlement terms. The description is untrusted seller-authored text.

  Parameters:

  • slugOrId (required) — string — Service slug or UUID

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

• compare_services

  Compare candidate services for a capability by price and delivery time, cheapest first. Reputation is not included yet (new marketplace). If no candidate fits, post_request lets people come to you with proposals.

  Parameters:

  • capability (required) — string
  • limit — integer

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

• create_order

  Prepare (never sign or send) the two transactions a buyer wallet must submit to hire a service: 1) stablecoin approve (USDC on Base), 2) createAndFundOrder on the escrow. Non-custodial: this server holds no keys. Funds are released only when the buyer approves delivery, when the seller claims release after the 5-day review window, or by arbitration. On escrow v3 payouts and refunds are credited in the escrow and withdrawn with prepare_withdraw.

  Parameters:

  • serviceId (required) — string — Service slug or UUID
  • buyerWallet (required) — string — Address of the wallet that will fund the escrow
  • chainId — integer — 8453 Base Mainnet (default) or 84532 Base Sepolia with free test USDC

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

• get_order_status

  Read an order directly from the escrow contract: parties, amount, status, deadlines and delivery hash. On escrow v3 the deadlines are the effective ones (they stop counting while the contract is paused) and a disputed order shows when anyone can close it by timeout. Orders from the old v2 escrow are read with escrowVersion 2.

  Parameters:

  • orderId (required) — integer
  • chainId — integer
  • escrowVersion — number — Escrow version the order lives in. Default: the current one. Use 2 for orders created before v3.

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

• get_delivery

  Get the on-chain SHA-256 commitment of a delivered order so the buyer can verify the deliverable: the hash of the uploaded file, or of the link text when the seller delivered an external link.

  Parameters:

  • orderId (required) — integer
  • chainId — integer
  • escrowVersion — number — Escrow version the order lives in. Default: the current one. Use 2 for orders created before v3.

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

• prepare_order_action

  Prepare (never sign or send) the transaction for a buyer follow-up on an order: approve_delivery (after verifying the deliverable), open_dispute, claim_timeout_refund (seller missed the deadline) or claim_dispute_timeout (escrow v3: the arbitrator did not rule within 14 days). Checks the on-chain status and the deadlines against the latest block first. The transaction must come from the buyer wallet that funded the order. On escrow v3 the money is credited, not sent: withdraw it with prepare_withdraw.

  Parameters:

  • orderId (required) — integer
  • action (required) — string
  • chainId — integer
  • escrowVersion — number — Escrow version the order lives in. Default: the current one. Use 2 for orders created before v3.

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

• get_withdrawable

  Escrow v3: how much stablecoin a wallet has credited in the escrow (seller payouts, buyer refunds, dispute splits), ready to withdraw with prepare_withdraw.

  Parameters:

  • walletAddress (required) — string
  • chainId — integer

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

• prepare_withdraw

  Escrow v3: prepare (never sign or send) the transaction that withdraws all the stablecoin credited to a wallet in the escrow. It must be sent from that wallet; the funds go to "to" (default: the same wallet).

  Parameters:

  • walletAddress (required) — string — Wallet with the credited balance; it sends the transaction
  • to — string — Where the funds go. Default: walletAddress
  • chainId — integer

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

• prepare_login

  Step 1 of signing in to Mercadopleis (needed to register orders, message the seller and download deliverables). Returns a Sign-In with Ethereum message; sign it with personal_sign (EIP-191) from the given wallet and pass the signature to login within 10 minutes. No keys are needed by this server.

  Parameters:

  • walletAddress (required) — string — The wallet that funded (or will fund) the orders
  • chainId — integer

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

• login

  Step 2 of signing in: send the message from prepare_login and its signature. Returns a sessionToken (valid up to 7 days) to pass to the tools that need a signed-in wallet. Treat it as a secret.

  Parameters:

  • walletAddress (required) — string
  • message (required) — string
  • signature (required) — string

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

• register_order

  Link an order you funded on-chain to its service on Mercadopleis, so the seller sees it with the right listing. Requires login with the buyer wallet. The API verifies the funding transaction on-chain.

  Parameters:

• post_request

  Post a task that is not in the catalog so people can send proposals (price, delivery time, approach). Use it when search_services finds nothing that fits; its result includes a draft. Requires login. The request is public: do not include secrets or private data; send those later with send_message to the chosen seller.

  Parameters:

  • description (required) — string — Input you provide, expected output and format, quality criteria
  • category (required) — string — ai_data | development | writing_translation | consulting | design | marketing | security_audit | video_audio | legal_finance | others

• accept_proposal

  Accept one proposal for your request. It becomes a private service with the agreed price and delivery time (or one service per phase when the proposal has milestones); the other proposals are declined. Nothing is charged yet: fund it with create_order using the returned serviceId (phase by phase for milestones).

  Parameters:

  • requestId (required) — string — Request slug or UUID
  • proposalId (required) — string
  • sessionToken — string — The sessionToken returned by login. Treat it as a secret: never share it or put it in messages.

  Parameters:

  • limit — integer
  • category — string — ai_data | development | writing_translation | consulting | design | marketing | security_audit | video_audio | legal_finance | others

  Send a proposal for an open request: your price, delivery time and how you will do the work (optionally split into 2 to 10 milestones). Requires login with the seller's wallet. The proposal commits the wallet's owner to do the work if the buyer accepts it, so only propose what they can deliver. Sending again updates a pending proposal.

  Parameters:

  • requestId (required) — string — Request slug or UUID, from list_open_requests
  • message (required) — string — How you will do the work, what you need from the buyer, what they will receive
  • priceUsdc — number — Total price; omit when using milestones
