## 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 apollo-org-search-793eddc8 -d '<json body>'
```

Example prompt: Search Apollo for software companies in San Francisco with 51 to 200 employees — use keywords like 'machine learning' and return the first 25 results.

## When to prefer this

Use this endpoint when you need to discover and filter organizations from Apollo's 275M+ contact database based on criteria like company name, industry, location, employee size, or keywords. Prefer this over Org Enrichment when you don't have a specific company identifier and need to prospect or search broadly. Best for building target account lists, prospecting in new markets, or finding companies that match a sales ICP.

## Known failure modes

- Invalid industry tag IDs returning empty results
- Employee range format incorrectly specified causing no matches
- Page number exceeding maximum of 500 returning an error
- Per page value exceeding maximum of 100 returning a validation error
- No organizations matching the provided filters returning an empty result set
- API call fails due to insufficient USDC balance

## Output

A paginated list of organizations matching the search criteria, including company profiles with details such as company name, industry, location, employee count, and other enrichment data available in Apollo's database.
