# Poll a protein annotation job

`POST /protein_annotate_poll`

## Request

- Base URL: `https://seqbench.com/api/v1`
- URL: `https://seqbench.com/api/v1/protein_annotate_poll`
- Auth: none required

Check an InterProScan job submitted via protein_annotate_submit. Returns {status, ready:false} while still running; once FINISHED, also returns the parsed domain architecture, per-match details, deduplicated GO terms, and `topology` — the MEMBRANE TOPOLOGY and SIGNAL PEPTIDE that EBI's default run includes (Phobius, TMHMM and SignalP), as {kind, start, end, source} with kind one of signal-peptide / transmembrane / cytoplasmic / non-cytoplasmic. Two predictors reporting nearly the same span are listed separately rather than merged, because a merged boundary is one neither produced. ⚠️ EBI runs every SignalP ORGANISM model whatever the protein is, so a human sequence comes back with gram-positive and gram-negative hits too; the source is named in full on every feature and Phobius — which is organism-agnostic and the only one that returns a full inside/outside topology — sorts first.

## Request body

- object
  - `jobId` string, required

## Response `200`

Tool ran successfully.

- SuccessResponse: Standard success envelope returned by every single-tool call.
  - `ok` unknown, required
  - `tool` string, required: The tool slug that ran.
  - `result` object, required: Tool-specific output object. Its shape depends on the tool — call `GET /{tool}` or see the docs for each tool's fields.
  - `gate` GateResult
    - `pass` boolean, required: True if and only if every hard check passed.
    - `checks` GateCheck[], required
      - `id` string, required
      - `label` string, required
      - `severity` 'hard' | 'soft', required
      - `pass` boolean, required
      - `message` string, required
      - `value` number
      - `threshold` string
    - `notChecked` string[], required: Honest list of what this gate does NOT verify.
  - `provenance` Provenance, required
    - `apiVersion` string, required
    - `tool` union, required: Tool slug, or an array of slugs (one per step) for a workflow.
      - string
      - string[]
    - `generatedAt` string, date-time, required: ISO 8601 timestamp of when the result was generated.

## Other responses

- `400`: Invalid argument or the tool could not run.
- `404`: Unknown tool.
- `429`: Rate limited (metered tools only). Body carries code `rate_limited` and retryable `true`; honor the Retry-After header.
- `503`: A metered tool is momentarily at capacity. The identical request should succeed after Retry-After; body carries code `upstream_unavailable`.
