## When to prefer this

Choose this endpoint when you need to understand how a specific company's website has changed over time — useful for competitive analysis, sales intelligence, or due diligence. Prefer this over generic web scraping when you need historical change data rather than a current snapshot. The pagination billing model (free subsequent pages) makes it cost-effective for retrieving large histories.

## Known failure modes

- Company domain not found or not tracked — returns empty results
- Invalid date format for first_seen_at_from or first_seen_at_until — returns 400 error
- Invalid page or limit parameter — returns 400 validation error
- Changing filter parameters while passing parentRequestId starts a new billable request
- Rate limiting or quota exceeded — returns 429 error
- Network timeout for large paginated result sets

## How this service works

Track website changes over time for a specific company 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 timestamped website change records for the specified company domain, each entry containing details about what changed on the website and when it was first detected. Includes billing metadata with a requestId for pagination continuity and cost management (subsequent pages on the same logical query are free).
