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.
Example use cases
Sourcing outbound sales leads
“Find me C-suite and VP-level executives at fintech companies with 100 to 500 employees based in New York or Boston — pull the first 100 results from Apollo.”
Recruiting senior engineers
“Search for senior and director-level software engineers located in San Francisco or Seattle, working at companies with at least 500 employees — show me page 1 with 50 results.”
Building a founder outreach list
“I need a list of founders and owners at early-stage companies in the healthcare space located in the UK — search Apollo and return the first page of 100 people.”
Technical details
Endpoint
POSThttps://x402.orthogonal.com/apollo/api/v1/mixed_people/api_search?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
