# Get Claim Endpoint

`GET /api/claims/{claim_id}`

Get a single claim with its sources.

``project_id`` is optional when the caller only has ``claim_id`` (for example
writeup previews); the store resolves by claim id alone.

## Path parameters

- `claim_id` string, required

## Query parameters

- `project_id` string, nullable

## Response `200`
