# NCBI OMIM Genetic Disorder Search via E-utilities

> NCBI OMIM Genetic Disorder Search via E-utilities 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 NCBI OMIM (Online Mendelian Inheritance in Man) database using NCBI E-utilities and returns matching UIDs for a given query string.

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 ncbi-omim-genetic-disorder-search-via-e-utilities-7d4da7c2 -d '<json body>'
```

Example prompt: Search the NCBI OMIM database for 'Marfan syndrome' and give me the matching OMIM UIDs.

## When to prefer this

Use this endpoint when you need to search the authoritative OMIM database for genetic disorders, hereditary conditions, or gene-disease associations and retrieve their canonical NCBI UIDs for downstream lookups. Prefer this over general web search when you need structured, machine-readable genetic disorder identifiers from the NCBI ecosystem.

## Known failure modes

- Empty result set if the query matches no OMIM records
- Malformed or missing query parameter returns an error
- NCBI E-utilities rate limiting may cause transient failures
- Very broad queries may return a large number of UIDs without ranking
- Service unavailability if upstream NCBI API is down

## How this service works

Search the NCBI OMIM (Online Mendelian Inheritance in Man) genetic-disorder database and return matching UIDs for query {q} via E-utilities. Query: ?q= Returns JSON.

## Output

A JSON object containing OMIM UIDs (numerical identifiers) that match the search query, along with metadata such as result count, query key, and WebEnv session token from NCBI E-utilities.
