# Melvea Honey Variety Catalog

> Melvea Honey Variety Catalog is a paid API for AI agents from api.melvea.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns structured compositional, sensory, and provenance data for 150+ honey varieties, with USDA color grades, flavor profiles, and citation counts linking to verified research sources.

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 melvea-honey-variety-catalog-e91e829c
```

Example prompt: Pull up the full catalog entry for Buckwheat honey — I want its USDA color grade, flavor profile, texture, best-use pairings, and how many research citations back its data.

## When to prefer this

Choose this endpoint when you need authoritative, research-backed compositional and sensory data for honey varieties — especially obscure long-tail varieties that general knowledge bases or foundation models get wrong. Prefer this over generic food databases when verifiable provenance (DOI/PMID citations) and USDA Pfund color grading are required.

## Known failure modes

- Unknown or unsupported honey variety returns empty result or 404
- Payment not processed (x402) results in 402 Payment Required with no data
- Malformed query parameters return 400 Bad Request
- Rate limiting may return 429 Too Many Requests
- Citation count present but underlying citations endpoint requires separate paid call

## How this service works

Structured varietal data and verifiable research provenance for 150+ honey varieties, including the obscure long tail foundation models get wrong. Every compositional datum resolves to a real, published source (DOI/PMID). Per variety: color grade (USDA Pfund band with measured or estimated source), intensity, flavor profile, texture, use cases, best-for pairing tags, primary and secondary countries, and a citation_count pointing to the paid citations endpoint. Melvea IP only.

## Output

A structured record per honey variety including USDA Pfund color band (measured or estimated), intensity rating, flavor profile descriptors, texture, recommended use cases, best-for pairing tags, primary and secondary country of origin, and a citation_count integer pointing to the paid citations endpoint for verified research sources (DOI/PMID).
