How this service works
Search for companies matching specific criteria. Supports filters for country, industry, employee count, revenue, keywords, technologies, company type, category, founded year, funding, and more. Also supports text search by name/domain and semantic natural language search. Max 10,000 results via page-based pagination. Use the scroll endpoint for larger result sets. 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. | ERROR: Unable to calculate price.
Output
A paginated list of company records matching the specified filters, each containing fields such as company name, domain, industry, employee count, revenue range, location (city, state, country), technologies used, company type, founding year, funding details, and category. Also returns a billing requestId for cost-free continuation pages of the same search.
Example use cases
Sales prospecting by tech stack
“Find me 50 companies in the US that use HubSpot and have between 50 and 250 employees — I'm looking for mid-market B2B businesses to target for a sales outreach campaign.”
Market research for VC deal sourcing
“I need a list of European fintech startups founded between 2019 and 2022 that have received funding — filter to companies with fewer than 100 employees and give me 100 results.”
Competitor landscape analysis
“Search for companies in the cloud infrastructure space in North America with revenues between $10M and $100M — I want to understand who the mid-size players are in this market.”
Technical details
Endpoint
POSThttps://x402.orthogonal.com/company-enrich/companies/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover or prospect companies based on structured criteria such as geography, industry, employee count, revenue, or technology stack. It supports both exact filter-based search and semantic/natural language queries, making it versatile for sales prospecting, market research, and lead generation. Prefer this over a generic web search when you need structured, filterable company data with pagination support. Use the scroll endpoint instead when you need more than 10,000 results.
Side effects
- Invalid or missing pageSize causes request failure
- Unsupported country code or NAICS code returns empty results or error
- Exceeding 10,000 result limit requires switching to scroll endpoint
- Changing filters mid-pagination starts a new billable request unexpectedly
- Price calculation error (noted in description) may affect billing transparency
- Overly broad queries may return irrelevant results up to the max page size
