What format does the API use?
All endpoints return application/vnd.api+json following the JSON:API specification. Consistent resource objects, relationships, and cursor-based pagination across every endpoint.
How do I authenticate?
Authentication is via Supabase JWT. Sign up for an API key, include it as a Bearer token in the Authorization header, and your role determines access level.
Is there a free tier?
Yes. The Developer tier gives you 1,000 API requests per day at no cost. Read-only access to all public endpoints, including the tariff search endpoint.
What markets do you cover?
The Energy API (Ofgem Tariff Information Labels) is live now. Telecoms (Ofcom Contract Summaries) and Banking (FCA Summary Boxes) APIs are planned and in development.
