Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability interpro-protein-lookup-via-uniprot-accession-c7b060ed -d '<json body>'
```

Example prompt: Can you look up the protein name, organism, and sequence length for UniProt accession P04637 using InterPro?

## When to prefer this

Use this endpoint when you need quick, structured protein metadata (name, organism, sequence length) from InterPro for a known UniProt accession. Prefer this over manually querying the InterPro or UniProt websites when working in an automated pipeline or agent workflow that needs programmatic access to protein annotations.

## Known failure modes

- Invalid or malformed UniProt accession returns an error or empty response
- Accession not found in InterPro database returns a 404 or empty result
- Missing 'acc' query parameter causes a bad request error
- InterPro upstream service unavailable leads to timeout or 5xx error

## How this service works

Protein metadata (name, organism, length) from InterPro for a UniProt accession (param acc, e.g. P04637). Query: ?acc= Returns JSON.

## Output

A JSON object containing the protein's name, the organism it belongs to, and the sequence length as recorded in InterPro, keyed to the provided UniProt accession.
