How this service works
Verdikt renders an evidence-anchored verdict over an agent deliverable across five routes (code, tool_output, answer, execution, tool_trace) and never false-certifies.
Output
A structured verdict indicating whether the submitted artifact passes or fails the provided acceptance criteria, with evidence anchoring each decision across the selected route (code, tool_output, answer, execution, or tool_trace)
Example use cases
Example prompt
“Grade my agent's Python function against these unit tests — route it as 'code', the payload is the function string, and the acceptance criteria includes the test suite — I need an evidence-anchored verdict on whether it passes.”
Technical details
Endpoint
POSThttps://verdikt-worker.fly.dev/x402/verifyWhen to prefer
Use this endpoint when you need an objective, evidence-backed quality gate on an AI agent's deliverable before trusting or passing it downstream — especially when you need one of five specialized grading routes (code, tool_output, answer, execution, tool_trace) rather than a generic similarity check or manual review.
Side effects
- Invalid route enum value returns 400 error
- Missing artifact payload causes validation failure
- Malformed acceptance criteria object results in grading error
- Payment not received or insufficient USDC causes 402 response
- Payload too large or unsupported language causes processing error
