# Verification Engine

> Trace-level claim verification and trust scoring

Verification analyzes LLM output claims and computes trust scores you can use in product decisions and QA workflows.

## Endpoints

* `POST /api/v1/verification/traces/{trace_id}/verify`
* `GET /api/v1/verification/traces/{trace_id}`
* `GET /api/v1/verification/traces/{trace_id}/summary`
* `GET /api/v1/verification/traces/{trace_id}/claims`
* `GET /api/v1/verification/config`

## Verifier Keys

Specify verifiers by key:

* `kb`
* `web`
* `multi_model`
* `citation`

## Typical Flow

1. Get a `trace_id` from trace/task APIs.
2. `POST .../verify` with `async_mode=true`.
3. Poll `GET .../traces/{trace_id}` for `verification_status` and claim details.

## Notes

* If a trace was already verified, the API returns completed status unless `force_reverify=true`.
* The summary endpoint is optimized for dashboard polling.
