    description: >-
      The OTLP HTTP API provides endpoints for exporting traces, metrics, and
      logs using the OpenTelemetry Protocol, the native wire format for
      transmitting telemetry data between instrumented applications, collectors,
      and observability backends.

    description: >-
      The OTLP gRPC API defines Protocol Buffers service definitions for
      exporting traces, metrics, and logs over gRPC. It is the primary
      transport for OpenTelemetry data between SDK instrumentation, the
      OpenTelemetry Collector, and observability backends, offering
      bidirectional streaming and efficient binary encoding.

    description: >-
      The OpenTelemetry Collector is a vendor-agnostic proxy for receiving,
      processing, and exporting telemetry data. It exposes HTTP and gRPC
      endpoints for receiving OTLP data and provides a configuration API
      for managing pipelines, receivers, processors, and exporters at runtime
      via the zPages diagnostic extension and config file hot-reloading.

    name: OpenTelemetry SDK API
    description: >-
      The OpenTelemetry SDK API specifies language-level interfaces for
      instrumentation, including the Tracer, Meter, and Logger APIs used
      by application code to create spans, record metrics, and emit log
      records. Implementations are available for all major programming
      languages including Java, Python, Go, JavaScript, .NET, Ruby, and
      others.
