OpenTelemetry Python API
JSON →OpenTelemetry Python API package. Current version: 1.40.0 (Mar 2026). TWO separate packages: 'opentelemetry-api' (interfaces + no-op implementations) and 'opentelemetry-sdk' (actual implementation). Installing only opentelemetry-api produces silent no-ops — all tracing calls succeed but nothing is recorded or exported. Must also install opentelemetry-sdk AND configure a TracerProvider AND call trace.set_tracer_provider(). Exporters (OTLP, Jaeger, Zipkin) are separate packages. All packages must be the same version.
