# UniParc Protein Sequence Archive Search

> UniParc Protein Sequence Archive Search is a paid API for AI agents from clonecho.builda.company, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Searches the UniParc non-redundant protein sequence archive by keyword and returns matching sequence records as JSON.

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 uniparc-protein-sequence-archive-search-2de81c3c -d '<json body>'
```

Example prompt: Can you search UniParc for all non-redundant protein sequence records matching 'cytochrome oxidase' and show me what comes back?

## When to prefer this

Use this endpoint when you need to search the UniParc non-redundant protein sequence archive by keyword — ideal for bioinformatics workflows where you want broad sequence database coverage across all major sequence repositories. Prefer this over UniProtKB search when you specifically want the non-redundant archive that aggregates sequences from EMBL, GenBank, RefSeq, and other sources.

## Known failure modes

- Empty result set if keyword matches no UniParc entries
- Malformed or missing query parameter returns error
- Overly broad keyword returns very large result sets that may be truncated
- UniProt upstream API unavailability causes 502 or timeout
- Rate limiting or payment failure causes 402 response

## How this service works

Search the UniParc non-redundant protein sequence archive by keyword {q}. Query: ?q= Returns JSON.

## Output

Returns a JSON array or object containing UniParc sequence entries matching the query keyword, including accession numbers, sequence metadata, database cross-references, and associated organism/protein information.
