How it works
- One key. Send it in the
X-API-Keyheader. It works for every source. - Plain JSON. Successful calls return the data with no wrapper. Costs and limits travel in headers.
- Failed calls are free. Bad parameters, no data, rate limits and source outages all cost 0 credits.
- Same rules everywhere. The REST API, the playground and the MCP server share one balance and one rate limit.
