How to choose an API?

Cached

Recommended

Served from cache and refreshed on a best-effort basis. Data may be up to 24 hours old. This is the recommended way to use pckt.sh API.

  • 2-3x less credits usage
  • Sub-100ms latency
  • 100% success rate

Real-time

Queried directly from the source on every request, with a cache window of up to 5 minutes. Use this when your use case requires the absolute latest data.

  • Real-time data
  • Sub-300ms latency
  • 99% success rate

HTTP or gRPC?

Every endpoint is available over plain HTTP/JSON. Endpoints on plans with gRPC access are also reachable over gRPC, using the same API key and credits.

HTTP

JSON over HTTPS at api.pckt.sh. Works with any HTTP client, no code generation required.

Authorization: Bearer YOUR_API_KEY

gRPC

Protobuf over HTTP/2 at grpc.pckt.sh:443. Lower latency and smaller payloads, with server reflection enabled so tools like grpcurl work without any .proto files.

authorization: bearer YOUR_API_KEY

Same token as HTTP, sent as request metadata instead of a header.

Rate limits

Rate limits are global across all endpoints, not applied per endpoint, and scale with your plan.
