• get_product_details read-only

  Find out what a product is and what it costs, from its page URL. USE THIS WHEN you have the URL of ONE specific product — a store listing, a marketplace item, a manufacturer's page — and you need its fields rather than its prose. Typical jobs: comparing the same item across several stores, tracking a price over time, checking whether something is in stock, ingesting a catalogue, or getting a product photo URL. DO NOT USE THIS FOR search-results or category pages (it returns one product, not a list), pages behind a login or paywall, or pages that are not about a product. It also cannot reach private or internal addresses. RETURNS name, description, brand, sku, price (a number), currency (ISO 4217), availability (in_stock | out_of_stock | preorder | unknown), images (up to 5 absolute URLs copied from the page, never invented) and variants. See the output schema for the exact shape. Any field the page does not state comes back null rather than guessed. HOW: the page is rendered in a real headless browser before extraction, so JavaScript-built pages work where a plain fetch returns an empty shell. COST $0.01 USDC per call over x402 (the quote lists every network you can pay on: Base, and Solana where offered). No account, no API key, nothing to install, and no gas — the facilitator sponsors it. Call once WITHOUT the payment argument to get back the payment requirements, sign a payment for the quoted amount with your own wallet, base64-encode the x402 payload, and call again with that string as `payment`. EVERY RESPONSE SAYS WHERE EACH FIELD CAME FROM. `provenance.declared` lists the fields whose values match what the merchant published in schema.org JSON-LD — their own number, the one they publish for Google. `provenance.inferred` lists the ones a model read off the page, which might be a strikethrough price or a neighbouring product. Act on declared values; verify inferred ones if the decision matters. A URL that redirects to what looks like a DIFFERENT page — a discontinued item bouncing to its category listing — is refused free of charge rather than answered with the wrong product. Retry with `allow_redirect: true` if you want whatever the URL resolves to. A failed extraction is not charged. Repeat calls for the same URL within 300 seconds are re-served from a recent render and marked `cached: true` with the render's original `fetchedAt`. Call `try_it_free` first if you want to see real output before spending anything. When to use: You have the URL of one product page. Use instead: compare_products for 2-5 URLs (one payment); try_it_free to see the output first. Returns: product (name, price, currency, availability, brand, sku, images, variants), provenance of each field, and the page fetched.

  Parameters:

  • url (required) — string — Absolute https:// URL of a single product page. Not a search or category page.
  • payment — string — Base64-encoded x402 payment payload. Omit on the first call to receive payment requirements.
  • allow_redirect — boolean — Default false. By default a URL that redirects to what looks like a different page (a discontinued item bouncing to its category listing) is refused free of charge, because extracting it would return a real product that is not the one you asked for. Set true if you want whatever the URL resolves to.

• try_it_free read-only

  Free. Run a real extraction against one fixed sample product page and return the result. USE THIS to decide whether the paid tools are worth paying for. It returns the identical shape get_product_details returns, produced by the identical code — not a hand-written example — so what you see is what you get. It takes no arguments and costs nothing. You cannot choose the page: pointing a free endpoint at arbitrary URLs would just be the paid tool with no toll. Use get_product_details for the URL you actually care about. When to use: Before paying, to see exactly what get_product_details returns. Use instead: get_product_details for a URL you choose. Returns: a real extraction of one fixed sample page.

• compare_products read-only

  Price the same product at several stores — up to 5 URLs in ONE call and ONE payment. USE THIS WHENEVER YOU HAVE MORE THAN ONE URL. Comparing an item across stores, checking a short list, or refreshing a handful of tracked prices. It returns full details for each URL so YOU can compare them; it does not rank them or pick a winner. Through get_product_details that is one EIP-3009 signature, one settlement and one round trip PER URL; this is one of each for the whole set. RETURNS one entry per URL in the order given, each with the same product and page objects get_product_details returns, plus ok/error so a single dead URL does not cost you the rest. COST $0.04 flat for up to 5 URLs — cheaper per page than calling get_product_details 5 times. BILLING, stated plainly: the price is flat, so a batch where only SOME URLs succeed is charged in full. A batch where NO url succeeds returns an error and is not charged. If you have one URL and are unsure it is live, get_product_details is the cheaper bet. Duplicate URLs are removed and not billed twice. When to use: You have 2-5 product page URLs, the same item at different stores or a short list. Use instead: get_product_details for a single URL. Returns: one entry per URL in order, each ok or with its error.

  Parameters:

  • urls (required) — array — Up to 5 absolute https:// product page URLs. Duplicates are removed and not billed twice.
  • payment — string — Base64-encoded x402 payment payload. Omit on the first call to receive payment requirements.
  • allow_redirect — boolean — Applies to every URL. See get_product_details for what it does.

• attest_page read-only

  Prove what a web page said, at a time, in a way someone who distrusts you can check. Renders the page and returns a signed, timestamped record of it: the text and its SHA-256, the HTTP status, the response headers, the serving IP, and the TLS certificate the site presented. Optionally a screenshot and its hash. All of it hashed into one claim and signed, so any single altered byte breaks the signature. Use it when a page might change or be denied later: terms of service before you agree, a price before you act on it, a policy you are relying on, a claim a competitor published, a listing that can be edited. Verification is free, needs no account, and does not depend on this service continuing to exist — the math is public and `verify_attestation` explains how to redo it yourself. We keep no copy, so the response you receive IS the evidence. Store it. $0.05 USDC per call over x402. A render that fails costs nothing. When to use: You may later need to prove what a page said at a moment: terms, a price, a claim. Use instead: screenshot_page or read_page when you only need to see or read it. Parameters: url: absolute https URL. screenshot: true adds an image to the evidence (larger response), default false. Returns: a signed, timestamped attestation (text, hashes, status, headers, IP, TLS certificate). Keep it: no copy is stored.

  Parameters:

  • url (required) — string — Absolute https:// URL of the page to attest to. Anything a dispute could turn on: terms of service, a price, a published policy, a competitor's claim, a listing that may be edited later.
  • payment — string — Base64 x402 payment payload. Omit it to receive a quote instead of an attestation; sign that and call again.
  • screenshot — boolean — Default false in MCP. A screenshot makes the evidence much stronger, but the image comes back inline as roughly 55,000 characters of base64. With it false the attestation is text-only and internally complete: it claims no screenshot and commits to no hash you cannot check. Set true when the visual appearance is the thing in dispute and you can afford the bytes.

• verify_attestation read-only

  Free, forever, no account. Hand back an attestation -- yours or one someone else gave you -- and find out whether the signature holds and whether we issued it. Works on attestations this service did not produce: the answer for those is a clear no, which is the point. Holds no database, so it keeps working whoever is running it. When to use: Someone handed you an attestation, or you want to check one of yours. Parameters: attestation: the full attest_page response or just its attestation object, as JSON text. Returns: whether the signature is valid and whether this service issued it, with the reasons.

  Parameters:

  • attestation (required) — string — The attestation as JSON text: either the whole response from attest_page or just its `attestation` object.

• check_my_balance read-only

  Free. Check how much USDC is left in your own wallet on Base, so you can tell your human before you run out. Returns the balance and whether it's below your threshold. Read-only: it moves nothing. Tollkit never holds anyone's funds or keys. When to use: You pay for tools from a wallet and want to know if it's running low. Use instead: wallet_balance for any wallet, chain or token. Parameters: address: the wallet you pay from. network: base (default) or sepolia. low_below: your low-balance threshold in USDC, default 1. Returns: the USDC balance and whether it's below low_below. Free.

  Parameters:

  • address (required) — string — Your wallet address (0x...). The address you pay from.
  • network — string — Default base. Use sepolia for test money.
  • low_below — number — USDC amount you consider low. Default 1.

• check_service read-only

  Free. Probes any x402 endpoint WITHOUT paying and reports what it actually charges, to which wallet, on which network, and how that compares with its public Coinbase Bazaar listing (price, recipient, distinct payers in the last 30 days). Returns facts and named signals such as pay_to_differs_from_listing; it does not score or recommend. Works for services that have nothing to do with Tollkit. Read-only: it sends one unpaid request, the way any buyer asks for a price, and never pays or changes anything. When to use: Before paying any x402 endpoint, to see what it really charges and who gets paid. Free. Parameters: url: the endpoint. One unpaid request is sent; nothing is paid. Returns: price, network, pay-to wallet, how they compare with its Bazaar listing, and named signals such as pay_to_differs_from_listing.

  Parameters:

  • url (required) — string — The x402 endpoint, e.g. https://api.example.com/v1/thing

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

• find_service read-only

  Free. Searches Coinbase's public x402 discovery index for services that do a task (e.g. 'product price lookup', 'send sms', 'web page screenshot'), then checks each result live without paying. Results are ordered by whether they returned a live price quote, then by distinct paying wallets; nobody pays for placement. Descriptions are the sellers' own words. When to use: You need a paid API for a job and don't know which seller has it. Free. Use instead: best_x402_tools for a ranking by real repeat buyers; check_service when you already have the URL. Parameters: query: the job in plain words. limit: how many to check live, default 5. Returns: matching services, each checked live: whether it answered with a price, the price, network, recipient and paying wallets.

  Parameters:

  • query (required) — string — What you need done, in plain words.
  • limit — integer — How many results to check, default 5.

• read_page read-only

  Read any public web page and get its visible text back: the words a person would see, with navigation and boilerplate stripped, plus the title and final URL after redirects. JavaScript pages are rendered in a real browser first. Up to 50,000 characters. Use it to read an article, a doc, a policy or any page you were given a link to. Chain it with a summarizer when the page is long. $0.002 USDC per page over x402. A page that fails to load, returns an error or has no text costs nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). When to use: You have one page URL and need its words: an article, doc, policy or listing. Use instead: read_pages for 2-5 URLs (one payment); page_brief for a summary instead of the full text; pdf_to_text for a PDF; screenshot_page for how it looks; attest_page if you may need to prove what it said. Parameters: url must be absolute http(s) and public (no logins, no private addresses). Returns: title, final_url after redirects, text (visible text, up to 50,000 characters), text_length and truncated.

  Parameters:

  • url (required) — string — Absolute http(s) URL of a public page.
  • payment — string — Base64 x402 payment payload. Omit it to receive a quote; sign that and call again.

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

• screenshot_page read-only

  Capture how any public web page looks: a 1280x800 JPEG from a real browser, returned as base64 with its SHA-256, the title and the final URL. Use it to see a page's layout, check that something renders, or hand the image to a vision model. The image is roughly 50-150 KB of base64 in the response. $0.003 USDC per capture over x402. A page that fails to load or returns an error costs nothing. For signed, timestamped evidence of a page use attest_page instead. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). When to use: You need to see a page: its layout, whether something renders, or an image for a vision model. Use instead: read_page when you only need the words (smaller and cheaper); attest_page for signed evidence of a page. Parameters: url must be absolute http(s) and public. Returns: a 1280x800 JPEG as base64, its sha256, title and final_url.

  Parameters:

  • url (required) — string — Absolute http(s) URL of a public page.
  • payment — string — Base64 x402 payment payload. Omit it to receive a quote; sign that and call again.
