Tools
| Tool | Description | Behaviour |
|---|---|---|
| airport_delays | Check US airport delays from the FAA's live National Airspace System status: ground stops, ground delay programs, arrival and departure delays (with minutes, trend and reason) and closures. Give an airport code, or none to list every airport with delays right now. $0.003 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). | Read-only |
| attest_page | 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. $0.25 USDC per call over x402. A render that fails costs nothing. | Read-only |
| best_x402_tools | Find the best paid x402 API for a task. Ranked by paying wallets and repeat buyers (not raw call counts, which are easy to inflate), one endpoint per seller, with price and a caution where a seller's numbers look unusual. Tollkit runs this ranking and sells tools too; its own are ranked the same way and marked sold_by_tollkit. $0.01 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. | Read-only |
| check_my_balance | 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 a link your human can use to refill you from their own wallet. Tollkit never holds anyone's funds or keys. | Read-only |
| check_service | 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 |
| company_due_diligence | Run due diligence on a US public company in one call: profile, revenue/profit growth, margins, leverage and cash ratios computed from SEC filings, key filings with links, and plain-English summaries of its latest 8-K material events. $0.03 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. | Read-only |
| company_snapshot | Get a one-call snapshot of a US public company from SEC EDGAR: profile, most recent filings with links, and key financials (revenue, net income, EPS, assets, cash, operating cash flow) for the last two fiscal years and the latest quarter. $0.006 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. | Read-only |
| compare_products | 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. | Not declared |
| exchange_rate | Convert between currencies at European Central Bank reference rates (30 currencies), for the latest business day or any day in the last 90. These rates are published free by the ECB at ecb.europa.eu and are for information only, not for transactions. $0.002 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). | Read-only |
| find_service | 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. | Read-only |
| geocode_address | Turn a US street address into latitude and longitude, with the standardized address, ZIP, county and FIPS code, state and census tract, from the US Census Bureau geocoder. US street addresses only (with a house number). $0.002 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). | Read-only |
| get_product_details | 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. | Not declared |
| get_service_info | Free. Price, network, and what this service returns. For a sample of the actual output rather than a description of it, call try_it_free instead. | Read-only |
| ip_lookup | Find where an IP address is: country, region, city, continent and approximate coordinates, for IPv4 or IPv6. City-level accuracy, not a street address. Data: IP Geolocation by DB-IP (db-ip.com), CC BY 4.0. $0.002 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). | Read-only |
| page_brief | Read any web page in a real browser and get a summary of it in one call, with its title and final URL. Says when the page was longer than the part summarized. $0.007 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. | Read-only |
| pdf_to_text | Read a PDF from a URL as text, page by page, with its title, author and page count. Works on text-layer PDFs up to 25 MB and 300 pages; scanned PDFs without a text layer are refused at no charge. $0.005 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). | Read-only |
| pretrade_check | Before trading a token on Base, Ethereum or Solana: its USD price and liquidity, plain warnings read from the chain, how big your planned trade is next to the pool (rough price impact), how much your wallet already holds, and recent web results about the token. Facts, not advice. $0.01 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. | Read-only |
| read_page | 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). | Read-only |
| screenshot_page | 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). | Read-only |
| search_and_read | Search the web and read the top pages in one step: returns the top web results plus the full visible text of the top 1-3 pages, each rendered in a real browser. Results that can't be read are skipped for the next one down. The fastest way to answer a question from fresh sources. $0.015 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. | Read-only |
| sec_company | Look up a US public company in SEC EDGAR by ticker or CIK: legal name, exchange, industry, state, fiscal year end, and its latest filings (10-K, 10-Q, 8-K, insider Form 4 and more) with direct links. Filter by form type, e.g. only 10-Ks. $0.002 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). | Read-only |
| sec_financials | Get a US public company's financials as filed with the SEC: revenue, operating income, net income, diluted EPS, total assets, liabilities, equity, cash, operating cash flow and shares outstanding — last 4 fiscal years plus the latest quarter, each tied to its filing. $0.005 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. | Read-only |
| token_check | Check a token before buying, sending or accepting it, on Base, Ethereum or Solana: what it is, its USD price and liquidity, and plain warnings read from the chain (no pool, thin liquidity; on Base and Ethereum the contract's owner and whether it is upgradeable or can mint, pause, blacklist or set fees; on Solana an active mint or freeze authority). $0.004 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). | Read-only |
| token_info | Look up a token on Base, Ethereum (ERC-20 contract) or Solana (SPL mint): name, symbol, decimals and total supply, plus mint and freeze authority on Solana, read live from the chain. Use it to confirm what an address actually is before acting on it. $0.002 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). | Read-only |
| token_price | Get a token's current USD price on Base, Ethereum or Solana, read from its deepest on-chain pool (Uniswap v3 against USDC or WETH; on Solana, Orca Whirlpools against USDC or SOL) rather than a price API. Returns the pool used, how much liquidity backs the price, and a flag when the pool is too thin to trust. $0.002 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). | Read-only |
| transaction_lookup | Look up a transaction on Base, Ethereum or Solana: did it succeed, when, who sent it, the fee, and every token movement with symbols and amounts (ERC-20 transfers; on Solana, SOL and token balance changes per owner). Use it to confirm a payment actually landed. $0.002 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). | Read-only |
| try_it_free | 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. | Read-only |
| verify_attestation | 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. | Read-only |
| wallet_balance | Check a wallet's balances on Base, Ethereum or Solana: native ETH or SOL, USDC (plus USDT on Ethereum and Solana), and any token contracts or SPL mints you list (up to 20), with symbols and decimals applied. Read live from the chain. $0.002 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). | Read-only |
| wallet_portfolio | Value a wallet in USD on Base, Ethereum or Solana: each holding (native coin, USDC/USDT and any tokens you list) priced from on-chain pools, the total, and warnings for thin pools or positions bigger than their pool. $0.008 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. | Read-only |
| weather_forecast | Get the US National Weather Service forecast for a US street address or a latitude/longitude: the next 7 days in day and night periods (temperature, chance of rain, wind, summary) plus any active watches, warnings or advisories. United States and territories only. $0.002 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). | Read-only |
| x402_market_dataset | Get the whole x402 market as one dataset: every active seller with rank, 30-day calls, estimated revenue, paying wallets, categories and unusual-number labels, plus category totals. Rebuilt weekly from Coinbase's Bazaar catalog. $0.10 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. | Read-only |
| x402_seller_lookup | Look up any x402 seller by hostname: its rank among all sellers, 30-day calls, estimated revenue and paying wallets, each endpoint's numbers and price, its categories and competitors, and labels where its numbers look unusual. Weekly, from Coinbase's Bazaar catalog. $0.02 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. | Read-only |
