Architecture

  • Framework: FastAPI + uvicorn

  • Payment protocol: x402 v2 (HTTP 402 + EIP-3009 USDC TransferWithAuthorization)

  • Facilitator: Coinbase x402 facilitator (https://x402.org/facilitator)

  • Network: Base Sepolia (testnet) / Base Mainnet

  • Data source: CoinGecko free API (no API key needed)

  • Discovery: Bazaar extension on all 402 responses, .well-known/x402, OpenAPI 3.0.3

Proven Revenue

  • 5 settled x402 payments on Base Sepolia ($1.04 total)

  • Payment log: x402_payments.jsonl in deployment

  • First settled payment: 2026-06-29T14:34:41Z

  • Both micro ($0.01) and standard ($1.00) price points proven

  • On-chain transaction hashes verified on BaseScan

Note: Current payments are self-pay proof-of-concept on testnet. The next milestone is a third-party paid call on Base Mainnet.

Part of Revenue Swarm

This API is one component of the Revenue Swarm — a Hermes Agent business system that:

  • Scouts revenue opportunities (DealWork, MYA, BountyBook)

  • Exposes paid APIs (x402)

  • Coordinates sibling agents (A2A/NATS)

  • Requests approval-gated spending (Stripe Link/Projects)

  • Records evidence tiers (R0-R5 receipt discipline)
