Tollkit

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). When to use: You need to know if a US airport has delays or a ground stop right now. Parameters: airport: a US code like JFK or KJFK; leave out to list every airport with delays. Returns: ground stops, ground delay programs, arrival and departure delays (minutes, trend, reason) and closures, live from the FAA.

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.

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. When to use: You want the best-proven paid API for a task, ranked by repeat buyers rather than raw calls. Use instead: find_service (free) for a quick live search; x402_seller_lookup for one seller in depth. Parameters: task: what the tool should do. limit: 1-20 results, default 10. Returns: ranked endpoints, one per seller, with price, paying wallets, repeat buyers and cautions.

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.

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.

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.

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.

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.

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. When to use: You want this service's prices, network and endpoints in machine-readable form. Free. Use instead: try_it_free to see real output. Returns: prices per tool, the payment network and recipient, and what each tool returns.

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.

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). When to use: You need the forecast for a place. Use instead: airport_delays for flight delays; geocode_address when you need coordinates for something else. Parameters: Give lat and lon (anywhere in the world) or address (US street addresses only). periods: 1-14 twelve-hour periods, default 14 (7 days). Returns: forecast[] with name, start and end, temperature, rain, wind and a summary; in the US, active NWS alerts too.

Search the web and get Google's top results as clean JSON: title, URL, snippet and date for each, plus the direct answer when Google shows one. Optional filters: freshness (past hour, day, week, month or year), include_domains or exclude_domains (up to 5 sites each), and type "news" for news articles with publisher and date. Up to 10 results. To get the pages' full text in the same call, use search_and_read. $0.003 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. When to use: You need sources or facts and don't have URLs yet; the snippets often answer it on their own. Use instead: search_and_read when you also need the full text of the top pages in the same call; crypto_news for crypto coverage with a mood read. Parameters: query is required. num: 1-10 results, default 5. country: two-letter code for local results. freshness, include_domains and exclude_domains narrow the results and can combine; very narrow filters can return nothing (refused free). type "news" searches news articles only. Returns: results[] with position, title, url, snippet and date (publisher for news), the answer box when Google shows one, and the filters applied.
