LangWatch Traces API

Search, retrieve, share, and unshare traces produced by instrumented LLM applications. Traces are the foundational observability primitive in LangWatch and arrive via OTLP/OpenTelemetry from Python or TypeScript SDKs (or any OTel-compliant client). Endpoints include /api/traces/search, /api/traces/{traceId}, /api/trace/{id}/share, and /api/trace/{id}/unshare.
LangWatch Traces API is one of 20 APIs that LangWatch publishes on the APIs.io network, described by a machine-readable OpenAPI specification.
This API exposes 1 machine-runnable capability that can be deployed as REST, MCP, or Agent Skill surfaces via Naftiko.
Tagged areas include Traces, Observability, and OpenTelemetry. The published artifact set on APIs.io includes API documentation, an OpenAPI specification, and 1 Naftiko capability spec.
