## 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 openmart-only-ids-search-0e465536 -d '<json body>'
```

Example prompt: Search Openmart for pizza restaurants in Chicago and give me just the business IDs — I want a lightweight list I can use to pull full details later.

## When to prefer this

Choose this endpoint when you only need business identifiers for downstream processing (e.g., batch enrichment or deduplication) and want to minimize payload size and cost. Prefer it over the full Search endpoint when you don't need business details upfront and want a faster, cheaper preliminary lookup.

## Known failure modes

- Invalid or missing search query returns an error or empty result set
- No businesses match the search criteria, returning an empty ID list
- Rate limiting or authentication failure if credentials are invalid
- Location not supported outside US/CA/AU coverage area

## How this service works

Lightweight search returning only business IDs.

## Output

A list of business IDs matching the search criteria, without full business record details such as contact info, reviews, or enrichment data.
