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 ebi-search-uniprot-full-text-search-cf1b479e -d '<json body>'
```

Example prompt: Search UniProt for all protein entries related to 'BRCA1' and show me the results.

## When to prefer this

Use this endpoint when you need to search the UniProt protein database by free-text keyword, gene name, protein name, or biological term and want structured JSON results. Prefer this over direct UniProt REST API calls when you need a simple paid-gateway interface to EBI Search with x402 micropayment support.

## Known failure modes

- Empty result set if query matches no UniProt entries
- Malformed or missing q parameter returns error
- EBI Search API upstream downtime causing 502 or timeout
- Overly broad query returning very large result sets
- Special characters in query causing parsing errors

## How this service works

Full-text search of UniProt protein entries for {q} via the EBI Search cross-domain API. Query: ?q= Returns JSON.

## Output

A JSON array of UniProt protein entries matching the search query, including protein names, identifiers, descriptions, and associated metadata returned via the EBI Search cross-domain API.
