Get companies that a person has invested in. 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.

Turn messy text — a web page, email, invoice, receipt, job posting, contract clause, product description — into strict JSON matching a schema YOU supply. The schema is enforced in code, not merely requested: output is parsed, validated, repaired once against the exact validation error, and the call FAILS with the violated constraint rather than returning unvalidated JSON. Fields not present in the input come back null instead of a plausible invention. Priced per call.
