Scans run automatically; no person reviews individual results.","version":"0.1.0","x-guidance":"Tanod Agents: Index of x402 endpoints and MCP servers (query, history, export) and agent-package scans. Pick by situation:\n- Use when an agent must decide what to list or price on x402: today's Bazaar listings, new sellers, payer gains and gaps. GET /v1/x402/pulse\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 price an x402 endpoint against listed prices for similar ones: median, quartiles, closest listings. POST /v1/x402/price-benchmark\n- Use when an agent must test that its wallet and x402 client can pay, or health-ping on a schedule, with a signed receipt. POST /v1/x402/pay-test\n- Use when an agent must check that a remote MCP server is up, what it is and which tools it lists before connecting. POST /v1/mcp/check\n- Use when an agent is looking for x402 endpoints or MCP servers by category, network, price or name. POST /v1/agents/query\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/agents; 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.

Downloads the published package (npm, PyPI, GitHub, ClawHub) or takes your upload, unpacks it in a sandbox and reads every file as text; never installs, imports or runs it. Checks: prompt/instruction injection and MCP tool poisoning, hidden Unicode text, remote code execution (curl|sh, eval of downloads, reverse shells), access to SSH keys, cloud credentials, .env files, browser and wallet stores, exfiltration endpoints (webhooks, paste sites, request catchers), install-time hooks (npm lifecycle scripts, setup.py, .pth), persistence and privilege escalation, over-broad MCP tools (shell, unscoped filesystem, arbitrary HTTP), typosquatted names, and known-vulnerable or malicious dependencies via OSV.dev (registry sources only; uploads are never sent to OSV). It cannot see tools registered dynamically at run time, code downloaded at run time, the contents of nested archives, or heavily obfuscated logic, and it does not execute or detonate anything; 'safe-looking' means no rule matched, not that the package is harmless. Typically 2-4 s for a registry package, 5-15 s for a GitHub monorepo, hard limit 60 s: a package too large to finish in time (e.g. a very large monorepo) gets a timeout result (verdict unknown; charged, like any result); scan a //subdir instead.
