# RNAcentral Full-Text Search via EBI Search API

> RNAcentral Full-Text Search via EBI Search API 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).

Performs full-text search of RNAcentral non-coding RNA sequences and entries using the EBI Search API, returning matched records as JSON.

## Facts

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-full-text-search-via-ebi-search-api-745d7900 -d '<json body>'
```

Example prompt: Search RNAcentral for non-coding RNA entries related to HOTAIR lncRNA in humans and return the matching sequence records.

## When to prefer this

Choose this endpoint when you need to search the RNAcentral comprehensive non-coding RNA sequence database by keyword, gene name, organism, or RNA type. It is ideal for bioinformatics workflows requiring discovery of ncRNA entries (lncRNA, miRNA, snoRNA, piRNA, etc.) without direct access to the EBI Search API. Prefer this over general web search when structured, database-quality RNA metadata and identifiers are needed.

## Known failure modes

- Empty query parameter returns error or empty result set
- Very broad queries may return truncated or paginated results requiring further navigation
- Misspelled gene or organism names yield no results
- EBI Search API downtime causes request failure
- Rate limiting or payment failure at the x402 proxy layer

## How this service works

Full-text search of RNAcentral non-coding RNA sequences for {q} via the EBI Search API. Query: ?q= Returns JSON.

## Output

A JSON object containing RNAcentral search results from the EBI Search API, including matched non-coding RNA entries with identifiers, descriptions, and associated metadata such as organism, RNA type, and sequence information.
