# Download a record of a submission {#top}

**Read** · `GET /v1/tenants/{tenant}/submissions/{submission}/{artifact}` · MCP tool `fetch`

Returns one record of a submission, chosen with `artifact`: the spec as stored, the list of build outputs, the software bill of materials (SBOM), the provenance statement, the build tools left in the image, a download link for the image, or the result of your last installation on a server. If a record does not exist yet, the refusal says why.

Roles that can call it: `viewer`, `builder`, `deployer`.

## Parameters

| Name | In | Required | Description |
|---|---|---|---|
| `tenant` | path | yes | Your tenant ID |
| `submission` | path | yes | The submission ID that `submit` returned |
| `artifact` | path | yes | Which record to get. `image` gives a signed download link that expires; `provisioning` gives the result of your last installation, also when it failed. One of `spec`, `artifacts`, `sbom`, `provenance`, `retained-tooling`, `image`, `provisioning` |

## Returns

A JSON object with these keys: `submission`, `tenant`, `artifact`, `content`, `guarantee`, `caller_authenticated`.

## Errors

| Code | HTTP | What it means |
|---|---|---|
| [`invalid_parameter`](/api/errors#invalid_parameter) | 400 | A value in your request does not have the expected format, for example a submission ID that is not a spec hash. Check the value against the field's description and try again. |
| [`no_acting_tenant`](/api/errors#no_acting_tenant) | 400 | Your request does not say which tenant you are acting for. Send your tenant ID in the `X-Tarsana-Tenant` header, or with `--as` on the command line. |
| [`isolation_refused`](/api/errors#isolation_refused) | 403 | This address belongs to a tenant ID you do not have access to. Check the tenant ID in the address and in your request header. |
| [`no_such_submission`](/api/errors#no_such_submission) | 404 | You have no submission with this ID. Check the ID that `submit` returned. |
| [`no_such_artifact`](/api/errors#no_such_artifact) | 404 | This submission does not have that record yet. The response says what state the build is in and what will produce the record. |
| [`image_endpoint_not_configured`](/api/errors#image_endpoint_not_configured) | 503 | Image downloads are not available on this Tarsana deployment. Contact Tarsana support if you need them. |
| [`unauthenticated`](/api/errors#unauthenticated) | 401 | Your request has no credential, or one that Tarsana does not recognise. Sign in with `login`, or send a valid access token. |
| [`forbidden`](/api/errors#forbidden) | 403 | Your role does not allow this operation. The response names the roles that do; ask for a credential with one of them. |
| [`rate_limited`](/api/errors#rate_limited) | 429 | You sent too many requests in a short time. Wait for the number of seconds in `retry_after_seconds`, then try again. |
| [`surface_fault`](/api/errors#surface_fault) | 500 | Something went wrong on our side. Try again later, and contact Tarsana support if it keeps happening. |
