How this service works
Takes free-form text (e.g., 'Series A startups in USA with 50–200 employees') and returns a list of matching companies. The endpoint interprets natural language queries and applies structured filters such as industries, funding stages, headcount ranges, and locations to identify relevant companies. 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 paginated list of companies matching the natural language query, including structured company details such as name, industry, funding stage, headcount range, and location, along with a pagination cursor and a billing requestId for free continuation pages.
Example use cases
Sourcing seed-stage AI startups
“Find me seed-stage AI companies in the United States with fewer than 50 employees — give me the first 20 results.”
Prospecting enterprise SaaS targets in Europe
“Search for B2B SaaS companies in Germany and the UK that have raised Series B or later and have between 200 and 1000 employees, give me 15 results.”
Mapping healthcare startups by headcount
“Show me healthcare startups in California with 50 to 500 employees that have received venture funding — first page of 10 companies please.”
Technical details
Endpoint
POSThttps://x402.orthogonal.com/fiber/v1/natural-language-search/companies?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover companies using flexible, human-readable criteria like 'Series A startups in the US with 50–200 employees' rather than manually specifying structured filter fields. It is especially useful for exploratory research, lead generation, or market mapping where the exact filter taxonomy is unknown. Prefer the sibling structured-filter endpoint if you already have precise industry codes, exact headcount numbers, or founding year ranges and want deterministic filtering without NL interpretation overhead.
Side effects
- Ambiguous or very broad queries may return low-relevance results
- Changing any non-pagination filter parameter starts a new billable request at $0.54
- Missing or invalid cursor may cause pagination errors
- Query terms that don't map to known industries or funding stages may return empty results
- Rate limiting or payment failure may block the request
