Latency Summary API for agents
Calculate p50, p95, p99, mean, min, and max from bounded latency samples. 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.

The source header follows this discovery route through challenge, payment and delivery without exposing the buyer or request body.
