API Playground tips

  • 1.Mock vs real responses: Responses shown here are simulated with realistic shapes. They mirror the structure returned by the selected provider, but values are randomized and not pulled from any real match.
  • 2.Rate limits: Most providers enforce per-minute and per-day limits. The x-ratelimit-* headers in the response show typical patterns — always honor the x-ratelimit-remaining value.
  • 3.Endpoint availability: Endpoints are filtered based on the provider’s supported capabilities (rest, websocket, odds). A provider without odds data won’t show /odds.
  • 4.Latency benchmarks: Latency values are based on real-world benchmark data when available (US-East/EU-West averages). Use them to compare providers, not as guarantees — your region and caching strategy will affect actual numbers.
  • 5.Copy as cURL: Click the button on the response panel to copy a ready-to-run command. Replace the API key placeholder with a real one to execute against the live provider.
