## 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 medapi-mesh-term-lookup-6fe4edc6 -d '<json body>'
```

Example prompt: What are the official MeSH terms for 'type 2 diabetes' — I need the standardized medical subject headings to use in a literature search.

## When to prefer this

Use this endpoint when you need to map free-text medical concepts to standardized MeSH controlled vocabulary, particularly for structuring literature searches, tagging clinical content, or enriching biomedical data with official terminology. Prefer this over general-purpose search when you specifically need NLM MeSH taxonomy compliance.

## Known failure modes

- Empty or missing 'term' field returns validation error
- Highly ambiguous or misspelled terms may return zero results
- Very broad terms may return large result sets
- Payment failure via x402 protocol blocks access
- Downstream NLM MeSH database unavailability causes service errors
