Technical details
Endpoint
POSThttps://x402.orthogonal.com/apollo/api/v1/mixed_companies/searchWhen to prefer
Use this endpoint when you need to search a large, well-maintained B2B company database (Apollo) with structured filters for location, industry, and headcount. Prefer this over general web search when you need structured firmographic data for sales prospecting, lead generation, or market research. It is especially useful when you need paginated, scalable access to hundreds of company records matching specific criteria.
Side effects
- Invalid or unknown industry tag IDs return empty results or errors
- Exceeding per_page limit of 100 causes a validation error
- Page numbers beyond 500 are rejected
- Malformed location filters return no results
- Payment failure (insufficient USDC) results in a 402 error blocking the request
- Overly broad queries may return irrelevant or low-quality matches
