aid: anchor-x402 name: anchor-x402 description: >- anchor-x402 operates a pay-per-call API surface for AI agents, billed with the x402 HTTP payment protocol instead of API keys or accounts. Eighteen stateless services run on AWS Lambda and FastAPI behind https://api.anchor-x402.com, each returning an x402 v2 402 PaymentRequired challenge that a caller settles per request in USDC on Base or Solana (select routes also settle JPYC on Polygon) via EIP-3009 transferWithAuthorization. The catalog spans on-chain anchoring and attestation, wallet sanctions and risk screening, Web3 data decoding, ENS/SNS name resolution, token pricing, x402 spend accounting, verifiable signed randomness, and LLM-backed content analysis, priced from $0.001 to $1.77 per call. The same 18 services are exposed over MCP (a hosted Streamable HTTP endpoint at https://api.anchor-x402.com/mcp whose tools/list is free and anonymous, plus an npm stdio package) and over a signed A2A JSON-RPC door at /v1/a2a, with a conformant A2A 0.3.0 agent card and a hosted Claude chatbot at chat.anchor-x402.com for non-developers. Source is MIT licensed and the operator publishes a trust portal that states plainly it holds no SOC 2, ISO 27001, PCI or HIPAA certification. deliveryModel: model: open-core license: MIT license_evidence: repo: hypeprinter007-stack/anchor-x402 spdx: MIT stars: 4 open_source: true commercial: true callable_host: false label: Open core · an OSS project plus a commercial hosted product confidence: medium source: -
