## 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 nih-nlm-clinical-tables-medical-conditions-search-efca695a -d '<json body>'
```

Example prompt: Search the NIH NLM Clinical Tables for medical conditions matching 'type 2 diabetes' and give me the standardized codes and display names.

## When to prefer this

Choose this endpoint when you need to resolve free-text medical condition names to standardized NIH NLM codes without requiring an API key. Ideal for clinical coding, EHR data entry, health AI agents, or medical billing workflows where NLM Clinical Tables coverage is sufficient. Prefer over general search engines or proprietary medical databases when open, standardized NIH terminology is required and no authentication is available.

## Known failure modes

- Empty result set if the search term does not match any known condition
- Ambiguous or overly broad terms may return too many results to be actionable
- Misspelled condition names may return no matches
- Service unavailability from the upstream NIH NLM endpoint may cause failures
- Invalid or missing input body returns a schema validation error

## How this service works

Search Medical Conditions from the NIH NLM Clinical Tables service by terms, no key. Returns matching codes and display names. For AI agents in health, coding, and clinical workflows.

## Output

Returns a list of matching medical conditions from the NIH NLM Clinical Tables, each with a standardized condition code and human-readable display name corresponding to the search term provided.
