# Re-check a record with the hosted MCP schema

`GET /api/v1/mcp/recheck`

## Request

- Base URL: `https://fonteum.com`
- URL: `https://fonteum.com/api/v1/mcp/recheck`
- Auth: HTTP bearer

REST bridge for the `fonteum_recheck_snapshot` MCP tool and source-only @fonteum/mcp 0.5.0 contract. Returns the hosted re-check envelope, including available source_file, as_of_date, snapshot_digest, and verifiable_url values for an identified retained snapshot; it is not the narrower attestation-check response.

## Query parameters

- `snapshot_id` integer

## Response `200`

Hosted MCP re-check envelope.

- object
  - `data` object, required
  - `provenance` object, required
  - `source_file` string, nullable, required: Exact retained source filename when one file represents the response; null for composite results or when no retained file is identified.
  - `as_of_date` string, nullable, required: Source publish or snapshot date when one date represents the response; null for composite results with dates in nested source blocks or when no source date is available.
  - `snapshot_digest` string, nullable, required: Digest of an identified retained snapshot object; null for composite results with digests in nested source blocks or when unavailable, and never a per-fact signature or live-chain-head substitute.
  - `verifiable_url` string, uri, required: Public source, methodology, or retained-snapshot re-check URL appropriate to the response.

## Other responses

- `400`: snapshot_id is not a positive integer.
- `401`: Missing or invalid Fonteum API key.
