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 Images: Image toolkit: resize, convert, compress, crop, metadata, hashes, favicons, OCR, QR codes, barcodes. Pick by situation:\n- Use when an agent needs image to text: extract text from an image such as a scan, screenshot or photo. POST /v1/ocr\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 produce a Code 128, Code 39, EAN, UPC-A or ISBN barcode image. Add output=url for a 24 h link. POST /v1/barcode\n- Use when an agent must convert a color between hex, RGB, HSL, CMYK and OKLCH, or check WCAG contrast. POST /v1/color/convert\n- Use when an image must be scaled to given dimensions, keeping or ignoring its aspect ratio. Add output=url for a 24 h link. POST /v1/image/resize\n- Use when an image must be changed between formats such as PNG, JPEG, WebP, GIF, TIFF, BMP, ICO or AVIF. POST /v1/image/convert\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/images; 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.

The PaymentRequired object is in the body and, base64, in the PAYMENT-REQUIRED header; accepts[].amount is in USDC atomic units (6 decimals). Also answered to an unpaid request whose input is missing or invalid: then the base price is quoted and `error` says what is wrong. A payment for a different amount than the input's price is refused with a new 402 (error price_mismatch) and never settled. The free tier is opt-in over HTTP: an unpaid call without the header X-Tanod-Free: 1 gets this 402 and consumes nothing.","headers":{"PAYMENT-REQUIRED":{"description":"base64 of the same x402 v2 PaymentRequired","schema":{"type":"string"}}},"content":{"application/json":{"schema":{"properties":{"x402Version":{"type":"integer","const":2},"error":{"type":"string"},"resource":{"properties":{"url":{"type":"string"},"description":{"type":"string"},"mimeType":{"type":"string"},"serviceName":{"type":"string"},"tags":{"items":{"type":"string"},"type":"array"},"iconUrl":{"type":"string"}},"type":"object"},"accepts":{"items":{"properties":{"scheme":{"type":"string"},"network":{"type":"string"},"amount":{"type":"string","description":"USDC atomic units (6 decimals)"},"asset":{"type":"string"},"payTo":{"type":"string"},"maxTimeoutSeconds":{"type":"integer"},"extra":{"type":"object"}},"type":"object"},"type":"array"},"extensions":{"type":"object","description":"extensions.bazaar: discovery metadata"}},"type":"object","required":["x402Version","resource","accepts"],"description":"x402 v2 PaymentRequired (also base64 in the PAYMENT-REQUIRED header)."}}}},"413":{"description":"Request body too large (not charged).","content":{"application/json":{"schema":{"properties":{"error":{"type":"object"}},"type":"object"}}}},"415":{"description":"Content-Type must be application/json (only with a payment attached; unpaid: 402).","content":{"application/json":{"schema":{"properties":{"error":{"type":"object"}},"type":"object"}}}},"422":{"description":"With a payment attached: input rejected (bad or blocked target); not charged, the payment is not used.","content":{"application/json":{"schema":{"properties":{"error":{"type":"object"}},"type":"object"}}}},"429":{"description":"Rate limited upstream; see Retry-After (not charged).","content":{"application/json":{"schema":{"properties":{"error":{"type":"object"}},"type":"object"}}}},"502":{"description":"The upstream response could not be produced or was too large (not charged).","content":{"application/json":{"schema":{"properties":{"error":{"type":"object"}},"type":"object"}}}},"503":{"description":"The service is busy or temporarily unavailable; see Retry-After (not charged).","content":{"application/json":{"schema":{"properties":{"error":{"type":"object"}},"type":"object"}}}},"504":{"description":"The upstream request took too long (not charged).","content":{"application/json":{"schema":{"properties":{"error":{"type":"object"}},"type":"object"}}}}},"security":[],"x-payment-info":{"price":{"mode":"fixed","currency":"USD","amount":"0.002000"},"protocols":[{"x402":{}},{"mpp":{"method":"tempo","intent":"charge","currency":"0x20C000000000000000000000b9537d11c60E8b50"}}]},"x-tanod-pricing":{"product":"imagepeek","service":"Tanod imagepeek","scheme":"exact","network":"eip155:8453","asset":"USDC","payTo":"0x593857A4a4F619543ea12394137C3004ce841720","networks":["eip155:8453","eip155:137","solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp"],"prices_usd":{"image_qr_read":"0.002"},"free_tier_per_ip_per_day":3,"free_tier_header":"X-Tanod-Free: 1"}}}},"servers":[{"url":"https://images.tanod.dev"}],"x-tanod-family":{"family":"images","mcp":"https://tanod.dev/mcp/images","main":"https://tanod.dev/openapi.json"},"tags":[{"name":"sitepeek","description":"sitepeek, the web page, document reader.
