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 Security: Contract and agent-package scans, phishing URL and OFAC checks, domain and header checks. Pick by situation:\n- Use when an agent holds Solidity source and needs static-analysis findings before deploying or trusting it. POST /v1/scan/source\n- Use when an agent must check a deployed contract's verified source for known risk patterns before interacting. POST /v1/scan/address\n- Use when an agent is about to send funds to or call an address and wants a quick risk check first. POST /v1/check/address\n- Use when an agent is about to install an agent skill or MCP package and wants its code scanned first. POST /v1/scan/package\n- Use when an agent must check a domain's DNS records, email authentication or TLS setup. POST /v1/domain/inspect\n- Use when an agent needs who registered a domain, IP or AS number, with dates, status and abuse contact. POST /v1/rdap\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/security; 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.
