"instructions": "Tollkit Extract — paid web tools over x402. No account, no API key. Two jobs: READ a product page (get_product_details, $0.05; compare_products, $0.15 for up to 5) and PROVE what any page said (attest_page, $0.25 — a signed, timestamped record for disputes). Start with try_it_free: it is free and shows the real extraction output. verify_attestation is free too, and works on attestations from anywhere. Plain web tools too: read_page ($0.005, any page as clean text) and screenshot_page ($0.01, a 1280x800 JPEG). Also: wallet_balance ($0.002), token_info ($0.002), transaction_lookup ($0.003), token_price ($0.003), sec_company ($0.005), sec_financials ($0.01), ip_lookup ($0.002), weather_forecast ($0.003), exchange_rate ($0.001). Weigh Station (find_service, check_service) is free and covers ANY x402 seller, not only this one. Every paid tool called WITHOUT a `payment` argument returns a quote rather than an error; sign it and call again.",

It also cannot reach private or internal addresses.\n\nRETURNS 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.\n\nHOW: the page is rendered in a real headless browser before extraction, so JavaScript-built pages work where a plain fetch returns an empty shell.\n\nCOST $0.05 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`.\n\nEVERY 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.\n\nA 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.\n\nA failed extraction is not charged.
