PQS injection detection - finds instruction override, role hijack, data exfiltration, and delimiter attacks; returns a sanitized prompt
Not used for Gateway
Catalogued so agents know it is dead/unreachable — Gateway will not route it. Still catalogued — dead/unreachable knowledge is index value. (Degraded — catalogued (dead/unreachable known) · not used for Gateway)
Indexed from this operator's public /.well-known/x402.json. Found is not operator-owned and is not attested. Claim or opt out.

$0.05GET https://promptqualityscore.com/api/preflightPass/Fail before you waste budget on a doomed call. Decide whether to make a paid LLM call before you make it. Preflight scores your prompt against an 8-dimension quality rubric (pass/fail at 28/80) and optionally pulls the target endpoint's on-chain trust signals — total payments, unique payers, last activity. Two-in-one circuit breaker for agents that don't want to waste budget on weak prompts or sketchy endpoints. (rev 2)
