## 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-62da57d2 -d '<json body>'
```

Example prompt: Can you look up the MeSH terms for 'type 2 diabetes mellitus' so I can use the standardized medical subject headings in a PubMed literature search?

## When to prefer this

Use this endpoint when you need to resolve free-text medical concepts into standardized NLM MeSH controlled vocabulary terms, particularly as a preprocessing step before constructing PubMed queries or tagging biomedical content with canonical terminology. Prefer this over general medical search when you specifically need MeSH headings rather than drug data, adverse events, or clinical trial records.

## Known failure modes

- Empty or vague term returns zero results with success:true and empty terms array
- Misspelled or non-medical term returns no matches
- Network timeout or service unavailability returns HTTP error
- Payment failure via x402 prevents access to endpoint
- Term too broad may return large unfiltered result set
