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 harvestpulse-food-preservation-guide-43a66a2b
```

Example prompt: What's the safest way to can tomatoes at home — give me the USDA-recommended method, how long they'll keep, whether it's beginner-safe, and any critical safety rules I need to follow?

## When to prefer this

Choose this endpoint when you need USDA-grounded, safety-rated guidance on home food preservation including shelf life, yield estimates, and critical safety rules for a specific produce and method combination. Prefer this over generic web search when you need structured, actionable data that an agent can parse and act on — particularly for safety-critical decisions like low-acid canning where botulism risk is real.

## Known failure modes

- Unsupported produce or method combination returns empty or null results
- Vague produce input (e.g. 'vegetables' instead of 'tomatoes') may return generic or no data
- Missing required query parameters (method or produce) may result in a 400 error
- Data may not reflect the latest USDA guideline updates if synthesis is not current

## How this service works

Food preservation guide — how to preserve produce: step-by-step home canning, fermenting, dehydrating, freezing, and pickling for any crop, with USDA food-safety guidelines, yields, and shelf life. For homesteading and local-food agents.

## Output

A JSON object containing the preservation method name, produce type, estimated shelf life with storage conditions, a beginner/intermediate/advanced safety rating, an estimated yield from a standard unit of produce, and a list of critical USDA-backed safety rules to follow during preservation.
