## 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-people-search-via-x402-orthogonal-com-3744aeb3 -d '<json body>'
```

Example prompt: Search Apollo for VP-level and director-level people in marketing at software companies with 200–1000 employees headquartered in the United States — give me the first page of 50 results.

## When to prefer this

Use this endpoint when you need to discover and list professional profiles at scale based on title, seniority, geography, or company characteristics — especially for sales prospecting or recruiting pipelines. Prefer this over company search when the target is individual people rather than organizations. Note that contact info requires a follow-up enrichment call.

## Known failure modes

- Invalid seniority enum value causes filter to be ignored or return an error
- Page number exceeding 500 returns no results or an error
- per_page exceeding 100 is rejected or capped
- Overly broad filters may return irrelevant or low-quality matches
- Empty filter set may return generic results without useful targeting
- Payment failure (insufficient USDC balance) blocks the request

## How this service works

Search Apollo database for people matching filters. Returns up to 100 results per page. Does not include emails/phones - use enrichment endpoints for that.

## Output

Returns a paginated list of up to 100 person profiles per page, each including name, job title, seniority level, company, and location. Contact details (email, phone) are NOT included — a separate enrichment endpoint must be called to retrieve those.
