Preflight

Before your AI agent pays a stranger’s API, Preflight checks whether that endpoint is alive, honestly priced, and actually delivers.

Prior work measured declaration: 67 of the first 10,000 agents expose a service record (arXiv:2606.12128). The two columns to its right are behaviour, measured live.

Check an endpoint

Passive checks only — one liveness probe and one unpaid quote request. Nothing adversarial, and no payment is attempted.

How this was measured

  • Third-party endpoints receive passive checks only — one request per round, identified by User-Agent, stopping on any refusal signal.
  • Adversarial checks (replay, idempotency) run only against endpoints we deployed ourselves, enforced in code, not by convention.
  • SAFE requires a completed payment. An endpoint that merely answers is UNKNOWN, not safe to pay.
  • Findings, not accusations. Every number is reproducible from a file in data/.
