# GET /v1/artifacts/{artifact_id}/manifest

> Get the structured manifest for one persisted artifact

Get the structured manifest for one persisted artifact

<Info>
  Audience: developers verifying a persisted artifact's file metadata and source context.
</Info>

## Coverage and source scope

Returns storage metadata, file size, checksum, optional filing and section context, and supported export formats for one organization-scoped artifact. Manifest citation fields are descriptive metadata; retain the cited filing reference when a downstream result needs source evidence.

## Canonical metadata

* `artifactId`
* `filename`
* `contentType`
* `storageMode`
* `byteLength`
* `lineCount`
* `checksumSha1`
* `filing`
* `section`
* `exportedFormats`

## Example request

<RequestExample>
  ```bash theme={null}
  curl -X GET -H "x-api-key: $SECAPI_API_KEY" -H "secapi-version: 2026-03-19" "https://api.secapi.ai/v1/artifacts/art_example_123/manifest"
  ```

## Integrity and source context

`checksumSha1`, `byteLength`, and `lineCount` describe the persisted payload. `filing` and `section` are optional context captured while building the bundle; preserve their accession number, filing URL, and section key when a reviewer must return to the underlying disclosure. `exportedFormats` names the formats accepted by the export route.

## Errors

A missing, inaccessible, or unresolved manifest returns `404 artifact_manifest_not_found`.

## Give this prompt to your agent

<Prompt>
  Use SEC API GET /v1/artifacts/{artifact_id}/manifest to get the structured manifest for one persisted artifact. Preserve `artifactId`, `filename`, `contentType`, `storageMode`, `byteLength`, `lineCount`, `checksumSha1`, `filing`, `section`, `exportedFormats` in the output. Return a concise markdown summary plus the exact structured payload fields that a downstream engineer or agent should keep using this result.
</Prompt>

## Failure posture

* compare content with the returned checksum only for the persisted payload, not as proof of filing authenticity
* retain filing and section context with any evidence workflow
* do not infer a missing section is empty disclosure text
