Changes to the H2GC Data API — the read-only JSON REST API for querying gambling-industry financial and reference datasets. Entries are dated, newest first.

Added

• Rate limiting is now enforced on the Data API endpoints (/v1/financials, /v1/reference, /v1/catalog): 100 requests/minute and 10,000 requests/day per API key — the limits already published on the Rate limits page. Requests over a limit receive 429 Too Many Requests with a Retry-After header; every response carries X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset. Clients staying within the published limits see no change.

Behaviour

• The platform's internal session authentication migrated from Clerk to WorkOS. Data API consumers are unaffected — x-api-key authentication is unchanged; only the OpenAPI document's internal security-scheme naming moved (clerkAuth → workosAuth, admin/onboarding surface only).

2026-07-01

Added

• Initial public release of the Data API (v1):
  • GET /v1/financials — query financial metrics with cursor-based pagination. Any dimension listed in the dataset catalog can be used as a filter.
  • GET /v1/reference — query reference data across global jurisdictions.
  • GET /v1/catalog — list available datasets and their queryable dimensions.
• API-key authentication via the x-api-key header (sk_live_...), issued through the invite/claim flow.
