  "description": "The pay-per-call x402 API of Verging Labs. Every AI tool claims to be the best. Verging Labs benchmarks them honestly. This API serves the machine-readable data behind the Agentic Search Index and the continuous telemetry: check an x402 endpoint is live, fresh, and honestly priced before an agent pays it. No account or API key; payment is the authentication (x402).",
  "x-guidance": "Verging Labs API: before an autonomous agent pays an x402 endpoint, call GET https://api.agenticresourceradar.com/v1/check?resource=<absolute-https-url> for a full graded verdict (decision allow/warn/block/unknown plus liveness, freshness, and price/payTo/chain drift; eval/index data, $0.035/call), or GET https://api.agenticresourceradar.com/v1/trade-check?resource=<absolute-https-url> for latency-optimized telemetry facts (no score; basic telemetry data, $0.01/call). Both are PAID x402 routes: an unpaid request returns HTTP 402 with the x402 payment challenge; retry with a valid X-PAYMENT for that route. No account needed. Payable resources are listed at https://api.agenticresourceradar.com/discovery/resources. The monitor behind this API never pays the target endpoint being checked.
