# Results formats

> Catalog of result artifact formats.

When a job completes, its [`results`](/api-reference/v0.4/jobs/get-job) object contains one entry per available result artifact, keyed by format identifier. Each entry is an `ArtifactDescriptor` — pass the descriptor's `id` to the [artifact endpoint](/api-reference/v0.4/jobs/get-job-artifact) to download the payload.

To fetch the JSON Schema for a format, call **`GET /v0.4/schemas/formats/{format}`** with the identifier.
