# Verify proof

> Verify a PrysmProof receipt by request ID — public, so anyone can independently confirm what ran.

<Note>
  **GET** `https://api.prysm1.com/v1/proof/{request_id}` · No authentication required
</Note>

Look up a [PrysmProof](/concepts/prysmproof) by its `request_id` to confirm which model,
provider, and mode served a request — and what it cost. This endpoint is public so a
third party can independently verify a record.

## Path parameters

<ParamField path="request_id" type="string" required>
  The `request_id` from a response's `prysm.proof` block.
</ParamField>

## Response

<ResponseField name="verified" type="boolean">
  `true` if a matching record was found.
</ResponseField>

<ResponseField name="request_id" type="string">
  The request ID that was looked up.
</ResponseField>

<ResponseField name="entry" type="object">
  The recorded usage entry — model, provider, mode, token counts, cost, and timestamp.
</ResponseField>
