Live x402 Endpoint Readiness Benchmark
This benchmark is generated from Ontario's verification graph. It should become more valuable as external services submit endpoints and recurring monitors add history.
Turn this evidence into launch checks and spend policy.
If this page describes a real workflow, use Ontario's free verifier and can-pay API first. Buy implementation help only when agents will touch paid tools, x402 endpoints, or spend-capable MCP workflows.

How to read the benchmark
A single ready report is useful. A history of ready reports with valid signatures and stable metadata is stronger.
Evidence: Service profiles expose history_count, ready_count, average score, latest report, and certification level.
Fix: For production agents, prefer Ontario Certified x402 over a one-off ready result.
