It handles the serialization and deserialization of trace identifiers and sampling decisions into HTTP headers or other carrier formats, allowing trace context to flow across service boundaries in microservice architectures.\n\nThe propagator integrates with the OpenTelemetry API and is designed to be used alongside the OpenTelemetry SDK and instrumentation packages. It depends only on opentelemetry-api and typing-extensions, keeping the installation lightweight. The package is production-stable, supports Python 3.10 through 3.14, and receives regular maintenance from the OpenTelemetry project.","worth_installing":"Yes. Install this if you need B3 trace propagation in an OpenTelemetry-instrumented application or are integrating with systems that use B3 headers. Low install friction, active maintenance, no security vulnerabilities, and permissive licensing make it a straightforward choice for distributed tracing scenarios."},"id":"opentelemetry-propagator-b3","links":{"html":"https://skillfed.io/packages/opentelemetry-propagator-b3","md":"https://skillfed.io/packages/opentelemetry-propagator-b3.md","pypi":"https://pypi.org/project/opentelemetry-propagator-b3/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-16","license_spdx":"Apache-2.0","license_treatment":"permissive","name":"opentelemetry-propagator-b3","python_support":"supports_current","summary":"OpenTelemetry B3 Propagator"},"popularity":{"monthly_downloads":4792404,"position":2229,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.44.0"}
