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 Chain: EVM and Solana reads: balances, tokens, eth_call, logs, receipts, gas, blocks, transactions, ENS. Pick by situation:\n- Use when an agent needs what a Hyperliquid perp costs to hold, or whether funding is flipping, before sizing a trade. POST /v1/defi/funding\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 must turn an ENS name into an address, or an Ethereum address into its ENS name. POST /v1/chain/ens\n- Use when an agent has raw transaction calldata and needs the function and arguments it encodes. POST /v1/chain/calldata\n- Use when an agent needs an ERC-20 token's name, symbol, decimals and supply before handling its amounts. POST /v1/chain/token\n- Use when an agent needs the ETH or ERC-20 balance of an address on Ethereum, Base or Robinhood Chain. POST /v1/chain/balance\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/chain; 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.
