## When to prefer this

Use this endpoint when you need to discover and map relational connections between companies within an investment portfolio dataset, particularly when you want to paginate cost-efficiently through large result sets using PredictLeads data via Orthogonal's x402 billing protocol. Prefer this over generic company search endpoints when the specific goal is portfolio-level relationship discovery with date-filtered connection windows.

## Known failure modes

- Missing or invalid required parameters returns a 400 error
- Changing filter parameters mid-pagination starts a new billable request instead of continuing the prior one
- Invalid parentRequestId causes pagination billing to fail or restart
- Rate limiting or quota exhaustion returns a 429 or 402 error
- No results found for the specified date filters returns an empty list

## How this service works

Discover connections across portfolio 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 discovered connection records between portfolio companies, including relationship metadata and timestamps for when connections were first and last seen. Also includes a billing.requestId for use as parentRequestId in subsequent pagination calls, with continued pages billed at zero cost.
