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 rnacentral-non-coding-rna-sequence-search-b52c08ed -d '<json body>'
```

Example prompt: Search the RNAcentral non-coding RNA database for microRNA sequences related to BRCA1 and return the results.

## When to prefer this

Use this endpoint when you need to search the EBI RNAcentral non-coding RNA sequence database specifically, such as looking up miRNA, lncRNA, tRNA, rRNA, snRNA, snoRNA, or piRNA records by gene name, identifier, organism, or keyword. Prefer this over general genomics APIs when the focus is on non-coding RNA annotation and cross-database RNA metadata.

## Known failure modes

- Empty results if query string matches no entries in RNAcentral
- Missing or malformed ?q= parameter returns error or empty response
- EBI upstream service downtime causing failed lookups
- Overly broad query returning too many results or being rate-limited
- Special characters in query string causing malformed request

## How this service works

Search the EBI RNAcentral non-coding RNA sequence database by query {q}. Query: ?q= Returns JSON.

## Output

A JSON array or object of non-coding RNA records from RNAcentral matching the query, including sequence identifiers, RNA types, organism information, sequence lengths, and database cross-references.
