## 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 fiber-ai-api-fiber-ai-people-search-26a592c6 -d '<json body>'
```

Example prompt: Find me verified contact profiles — including email and phone — for Chief Marketing Officers at Series B SaaS companies in the United States with between 50 and 200 employees using Fiber AI's people search.

## When to prefer this

Use this endpoint when you need to find multiple people matching a set of professional criteria — such as job title, seniority, company size, industry, or geography — and want verified contact details including email and phone. Prefer this over the single Person endpoint when you don't have a specific LinkedIn slug or email in hand, and over the Company Search endpoint when your primary output target is individual contacts rather than organizations.

## Known failure modes

- No results returned when filters are too narrow or niche — relax filters to broaden scope
- Invalid filter values (e.g. unrecognized seniority level or location format) return a 400 validation error
- Authentication failure returns a 401 if API credentials are missing or invalid
- Rate limit exceeded returns a 429 if too many requests are made in a short period
- Empty result set for rare combinations of company + title + location filters

## How this service works

Search for people using filters Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.

## Output

Returns a list of enriched person profiles matching the applied filters, each including verified contact details such as email addresses, phone numbers, LinkedIn profile URLs, current job title, company affiliation, and location data.
