**Canonical:** https://apis.io/apis/jaeger/jaeger-collector-api/

**Documentation:** https://www.jaegertracing.io/docs/latest/apis/

Jaeger Collector API is one of 7 APIs that [Jaeger](https://apis.io/providers/jaeger/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Collector, Distributed Tracing, gRPC, and OTLP. The published artifact set on APIs.io includes API documentation, an API reference, and a GitHub repository.

The Jaeger Collector API receives trace spans from instrumented applications and SDKs. Since Jaeger v1.11 the primary protocol is the jaeger.api_v2.CollectorService gRPC endpoint; the collector also accepts OTLP traces (binary gRPC, Protobuf over HTTP, JSON over HTTP) since v1.35, as well as legacy Thrift over UDP and HTTP formats.
