## 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-via-locus-x402-3529fec7 -d '<json body>'
```

Example prompt: Search Apollo for SaaS companies in San Francisco with 51 to 200 employees — I want to find leads in the HR tech space, page 1 with 25 results.

## When to prefer this

Use this endpoint when you need to search and discover companies/organizations by name, keyword, industry, location, or size — especially when building B2B prospect lists, doing market research, or identifying target accounts. Prefer this over people/contact search when your primary entity of interest is the company itself rather than individual contacts. The x402 micropayment model at $0.005 per call makes it cost-effective for iterative searches.

## Known failure modes

- Invalid or missing search parameters return empty results
- Unsupported industry_tag_ids return no matches
- Page number exceeding 500 returns an error
- per_page exceeding 100 is rejected
- Insufficient USDC balance causes payment failure
- Rate limiting may occur with rapid successive calls
- Malformed location strings may return no results
