## How to call it through Zero

```sh
zero fetch --capability melvea-honey-variety-citations-api-2ad6ef87
```

Example prompt: Can you pull up the verified scientific citations — with DOIs or PMIDs — that back the compositional and sensory data for manuka honey on Melvea?

## When to prefer this

Use this endpoint when you need to verify or cite the scientific basis behind a specific honey variety's data — such as when building a research report, fact-checking honey product claims, or linking users to primary sources. Prefer this over general web search when you need pre-vetted, DOI/PMID-resolvable citations specific to honey varieties.

## Known failure modes

- Invalid or unknown honey variety slug returns 404 not found
- Missing slug parameter results in routing error
- Payment failure (x402) blocks access if USDC payment not processed
- Rate limiting may apply if too many requests are made in succession
- Variety exists but has no citations yet returns empty array

## How this service works

Per-variety research citations backing a honey variety's compositional and sensory data — verified, Rule-11-clear, each resolvable to a real published source (DOI/PMID). Bibliographic records only.

## Output

A list of bibliographic records for peer-reviewed, Rule-11-cleared publications supporting the specified honey variety's compositional and sensory data, each with a resolvable DOI or PMID identifier.
