## 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 usda-ams-market-news-via-mymarketnews-api-12af2af8
```

Example prompt: Can you search the USDA AMS Market News catalogue for reports about feeder cattle prices and show me the top 10 results?

## When to prefer this

Use this endpoint when you need official, authoritative USDA agricultural commodity price and market data — livestock, grain, dairy, or produce — either to discover available reports by keyword or to pull the latest structured price/volume rows from a known report. Prefer it over general web search when you need structured tabular market data directly from the government source rather than news articles or third-party summaries.

## Known failure modes

- Missing or invalid MARS API key returns an authentication error
- Invalid or non-existent slug ID returns no data or an error
- Search query exceeding 100 characters is rejected
- limit parameter outside 1–200 range may return an error or be clamped
- Non-existent section name for a slug returns empty rows or defaults to first section
- Network timeout from the upstream USDA MyMarketNews API

## How this service works

USDA AMS Market News (official MyMarketNews API): search the catalogue of livestock, grain, dairy, fruit/vegetable and other market reports by title, or pass a report slug id to get its latest published rows (prices, volumes, report date). Data straight from USDA; needs the owner's free MARS API key.

## Output

For catalogue searches: a list of matching report titles with their slug IDs, sections, and metadata. For slug-based lookups: the report header, narrative text, and tabular data rows (prices, volumes, units, report date) from the requested section.
