Portable intent card · agent-reliability-security
Turn an OpenAPI document into a compact operation index for planning and tool selection. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.
Intent to transaction
The source header follows this discovery route through challenge, payment and delivery without exposing the buyer or request body.
