How this service works
Fetch funding signals with filtering by date, country, round type, amount, industry, and more. 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
A paginated list of funding signal records, each containing company name, funding round type, amount, currency, date, country, industry, and related metadata. The response includes billing information with a requestId that can be used as parentRequestId for free subsequent pages of the same query.
Example use cases

“Show me all biotech funding rounds from the last 7 days globally, sorted by amount descending — I want to see up to 100 results.”
Source leads in European SaaS seed rounds
“Find seed-stage funding rounds in European SaaS companies from the last 3 months, with amounts between $500K and $5M — I'm looking for potential enterprise software leads.”
Track late-stage US tech fundraising this quarter
“Pull Series C and Series D funding signals for US tech companies this quarter, amounts over $50M, sorted by most recent date first.”
