# Verify

## VCDM verification

VCDM verification is usually done in context of a presentation request as [documented with the presentations endpoint](/truvera-api/presentations.md). You probably do not want to call the verify endpoint directly.

This route allows manual verification of issued/received credentials and presentations. Verification will check that the JSON-LD document's cryptographic proof is correct and that it has not been revoked. It will return a verification status with a boolean verified result.

A verifier upon receiving a verifiable presentation verifies the validity of each credential in the presentation. This includes checking the correctness of the data model of the credential, the authenticity by verifying the issuer's signature and revocation status if the credential is revocable. It then checks whether the presentation contains the signature from the holder on the presentation, including the given challenge.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.truvera.io/truvera-api/verify.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
