## 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-entry-lookup-d6e3ba7e -d '<json body>'
```

Example prompt: Can you look up the InterPro entry IPR002117 and tell me what protein family it represents along with any associated GO terms?

## When to prefer this

Use this endpoint when you need structured metadata and GO term annotations for a specific InterPro entry by accession. Ideal for bioinformatics pipelines that annotate proteins, map domain functions, or cross-reference Gene Ontology categories from a known InterPro ID.

## Known failure modes

- Invalid or malformed InterPro accession returns an error or empty result
- Accession does not exist in InterPro database returns 404 or null
- Missing required ?id= parameter returns an error response
- Network timeout for slow database queries

## How this service works

Detail and GO terms for one InterPro entry by accession (param id, e.g. IPR002117). Query: ?id= Returns JSON.

## Output

A JSON object containing detailed information about the specified InterPro entry, including its name, type (family, domain, homologous superfamily, etc.), description, member database signatures, and associated Gene Ontology (GO) terms with their IDs, names, and categories.
