OpenAPI Specification

openapi: 3.2.0
info:
  title: LogicNodes A2a API
  version: 1.0.0
  description: 'Blockchain and finance tools AI agents can trust: exact answers or typed errors, never a plausible guess. 40+ tools for EVM chains and Aptos (balances, token amounts, transaction status and receipts, contract and calldata decoding, payment verification, gas on 14 chains), exact finance math, and ERC-8004 agent reputation. Every answer carries a receipt timestamped into Bitcoin. Free tier; pay per call in USDC via x402 on 13 networks, no API key.'
  x-guidance: 'How to use LogicNodes: 1) GET /v1/tools lists every tool with its JSON Schema. 2) POST /v1/tools/<name> with a JSON body, e.g. POST /v1/tools/evm_balance {"chain":"eip155:8453","address":"0x..."} or POST /v1/tools/token_amount_convert {"chain":"eip155:8453","asset":"<token address>","amount":"1.5","direction":"toBase"}. 3) Read "ok": true with "value", or "ok": false with a typed error: INVALID_INPUT (fix the field named), AMBIGUOUS_INPUT (pick one of the options listed and call again), NOT_FOUND, UPSTREAM_ERROR (retry). Chains are CAIP-2 ids (eip155:8453 Base, eip155:1 Ethereum, aptos:1); names like "base" are refused. Amounts are decimal strings, never floats. Pricing: free tools are unlimited; priced tools are free for 25 calls per day per IP, then the same URL returns 402 with x402 terms (USDC on Base, Solana, Polygon, Arbitrum and more: /v1/payments/methods); pay and retry. A failed call is never charged. MCP: /mcp/v2. Full guide: /agent-guide.'
