A focused part of Tanod (https://tanod.dev/openapi.json lists every route).\n\nPayment: x402 v2 exact, USDC on Base or Polygon or Solana (primary eip155:8453), no account or key: unpaid calls get 402; retry with PAYMENT-SIGNATURE. Prices: `x-payment-info`.\n\nFree tier: daily per-IP pool (`x-tanod-pricing`). HTTP: send X-Tanod-Free: 1. Automatic on MCP.\n\nTanod is operated by an autonomous AI agent on behalf of its owner. Scans run automatically; no person reviews individual results.","version":"0.1.0","x-guidance":"Tanod Util: Developer utilities: encode, hash, HMAC, IDs, JSON, data conversion, cron, time zones, QR codes. Pick by situation:\n- Use when an agent must hand a person text or a URL as a scannable QR code image. Add output=url for a 24 h link. POST /v1/qr\n- Use when an agent must turn a city name into coordinates, or coordinates into the nearest city. POST /v1/geocode\n- Use when an agent must know the public holidays of a country and year before scheduling dates. POST /v1/holidays\n- Use when an agent must parse a phone number and format it as E.164 or national before storing or dialling it. POST /v1/phone\n- Use when an agent must check the format and check digits of an IBAN, VAT, ISBN, LEI or similar ID. POST /v1/validate\n- Use when an agent has a User-Agent string and needs the browser, OS, device and a bot flag. POST /v1/useragent\nPay per call with x402 v2 (scheme exact, USDC on Base or Polygon or Solana, primary eip155:8453); no account or API key. Also payable in USDC on Polygon (eip155:137), Solana (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp): the 402 lists one requirement per network, Base first. A call without payment gets HTTP 402: the PAYMENT-REQUIRED header (and the JSON body) carries the requirements; sign one and retry with the PAYMENT-SIGNATURE header. For a valid input the 402 quotes the exact price; for a missing or invalid input it quotes the route's base price and its error says what is wrong. With a payment attached, invalid input is refused (422, or 404/413) and the payment is not used; a payment for a different amount than the input's price (e.g. the base price for a large input) is refused with a fresh 402 and never settled. Payments settle only after the input is accepted. MPP works too: the 402 also carries a WWW-Authenticate: Payment challenge (Tempo, USDC.e); pay it with mppx, the Tempo CLI or AgentCash.\nFree tier: a daily per-IP pool; an unpaid valid call with header X-Tanod-Free: 1 uses it first (without the header it gets the 402). On MCP the free tier is automatic.\nThe same tools are on MCP (streamable HTTP) at /mcp/util; longer docs at /llms.txt. Every result is automated and heuristic, not an audit: findings can be false positives, and a clean result is not proof that code or a package is free of risk.
