# EBI GWAS Catalog SNPs by Gene

> EBI GWAS Catalog SNPs by Gene 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).

Returns SNPs mapped to a gene from the EBI GWAS Catalog, given an HGNC gene symbol.

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-gwas-catalog-snps-by-gene-606bf4e5 -d '<json body>'
```

Example prompt: Can you pull all the SNPs mapped to the BRCA2 gene from the EBI GWAS Catalog?

## When to prefer this

Use this endpoint when you need to quickly retrieve GWAS-mapped SNPs for a specific gene by its HGNC symbol, especially for bioinformatics pipelines, genomics research, or variant enrichment workflows where EBI GWAS Catalog data is the source of truth.

## Known failure modes

- Invalid or unrecognized HGNC gene symbol returns empty results or error
- Gene with no GWAS hits returns empty SNP list
- Missing gene parameter causes bad request response
- Network or upstream EBI API unavailability causes timeout or error

## How this service works

SNPs mapped to a gene in the EBI GWAS Catalog (param gene = HGNC symbol, e.g. BRCA2). Query: ?gene= Returns JSON.

## Output

A JSON payload listing SNPs (single nucleotide polymorphisms) that are mapped to the specified gene in the EBI GWAS Catalog, including variant identifiers and associated study metadata.
