## 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 uniprot-reference-proteomes-search-985aa35a -d '<json body>'
```

Example prompt: Search UniProt reference proteomes for Escherichia coli and give me the matching proteome records.

## When to prefer this

Use this endpoint when you need to search UniProt reference proteomes by organism name or keyword, especially when building bioinformatics pipelines, enriching biological datasets with proteome metadata, or looking up canonical proteome identifiers for model organisms. Prefer this over general web search when structured, machine-readable proteome data from UniProt is required.

## Known failure modes

- No results returned for obscure or misspelled organism names
- Empty result set if query term matches no reference proteomes
- Malformed query string may return an error or empty response
- Rate limiting or payment failure for the x402 micropayment protocol
- Unexpected JSON structure if UniProt API schema changes upstream

## How this service works

Search UniProt reference proteomes by organism keyword {q}. Query: ?q= Returns JSON.

## Output

A JSON array or object containing UniProt reference proteome records matching the organism keyword query, including proteome identifiers, organism names, taxonomy information, and related metadata.
