## 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-8143c05e -d '<json body>'
```

Example prompt: Search Apollo for software companies with 50-200 employees headquartered in Austin, TX that are in the SaaS industry — I want to build a prospect list.

## When to prefer this

Use this endpoint when you need to discover or prospect organizations/companies based on firmographic criteria such as industry, size, location, or revenue. Prefer over general web search when you need structured, enriched company data with contact-ready firmographics. Best for B2B lead generation, market research, and building targeted prospect lists. Use the companion people-search endpoint when you need individual contacts rather than company-level data.

## Known failure modes

- No matching organizations found for given criteria — returns empty result set
- Invalid or unsupported filter parameters — returns 400-level error
- Rate limit exceeded — returns 429 error
- Authentication or payment failure — returns 401 or 402 error
- Overly broad query returning too many results — may be truncated
