Hey ACK team — been building x402 infrastructure and wanted to flag something that might complement what you're doing here.
x402 Service Discovery API is a discovery and routing layer for x402-enabled services:
- 251+ indexed services from x402.org/ecosystem, Coinbase Bazaar, awesome-x402
- 6 MCP tools (
x402_discover, x402_health_check, x402_trust, x402_route, x402_facilitator_check, x402_register) for Claude/Cursor/Windsurf
- ERC-8004 trust verification — agent-registered provider validation before payment
- Routing strategies: cheapest, fastest, most trusted, or composite score
- Auto-scans for new services every 6 hours
For ACK workflows specifically: agents using your commerce kit need to find what services to pay for before initiating any transaction. The discovery layer is the missing upstream step — "what is available and at what price?" before the payment handshake happens.
Also built x402-payment-harness (pip install x402-payment-harness) — Python client for x402 payments without CDP wallet dependency, which might be useful as a reference implementation.
Happy to chat about integration patterns or add any ACK-tracked services into the discovery catalog.
