How this service works
Low-latency pre-action screening for routine agent responses and tool-call decisions.
Output
Returns a JSON object containing a verdict (pass/fail/flag), a confidence score (0–1), a human-readable reason string, a drift score and drift mode indicating how much the action deviates from baseline policy, the policy version used, an input hash for audit traceability, a chain index for sequencing in multi-step audits, and a transaction hash recording the x402 micropayment.
Example use cases
Pre-flight check on agent GET action
“My autonomous agent is about to send a GET request — can you run a fast policy audit on it first and tell me whether it gets a pass or fail verdict and how confident the evaluator is?”
Real-time drift detection for agent pipeline
“Before my agent executes this DELETE request, audit it against the current policy and let me know the drift score and whether anything looks off.”
Compliance gate in multi-step agent workflow
“I'm building an agentic workflow and I need a lightweight policy check inserted before each outbound HTTP action — run the fast DCL evaluator on this HEAD request and return the verdict and reason so I can decide whether to proceed.”
Technical details
Endpoint
GEThttps://bazaar.fronesislabs.com/evaluate/fastWhen to prefer
Choose this endpoint when you need a low-latency (real-time) policy gate before a GET, HEAD, or DELETE action and can tolerate a slightly lower confidence bar in exchange for speed. Prefer the sibling 'Strict pre-action audit' endpoint when higher confidence is required and latency is acceptable. Use this fast variant inside tight agent loops where every millisecond counts and you want a quick pass/fail before committing to an action.
Side effects
- Missing or malformed 'input' object returns a validation error
- Unsupported HTTP method (e.g. POST, PUT) rejected with enum constraint error
- Payment not provided or insufficient USDC causes 402 Payment Required response
- Policy service unavailable returns 503 or timeout
- Ambiguous or empty query params may reduce confidence score without failing the call
