* ## Real-time data The only real-time path to get tracing data is to ingest via OpenTelemetry (`POST /api/public/otel/v1/traces`) and retrieve via Observations API v2 (`GET /api/public/v2/observations`) and Metrics API v2 (`GET /api/public/v2/metrics`). Other public API write and read endpoints can delay data by about 10 minutes. Direct OpenTelemetry exporters must send the `x-langfuse-ingestion-version: 4` header; current Python and JS SDKs already do. See the [Public API docs](https://langfuse.com/docs/api-and-data-platform/features/public-api) and [real-time ingestion](https://langfuse.com/integrations/native/opentelemetry.md#real-time-ingestion). ## Authentication Authenticate with the API using [Basic Auth](https://en.wikipedia.org/wiki/Basic_access_authentication), get API keys in the project settings: - username: Langfuse Public Key - password: Langfuse Secret Key ## Exports - OpenAPI spec: https://cloud.langfuse.com/generated/api/openapi.yml - Self-hosted deployments: interactive API reference at `/api/docs` and OpenAPI spec at `/api/openapi.yaml`

/// **Deprecated:** On Langfuse Cloud, Langfuse v3 is deprecated and this endpoint will be removed on November 16, 2026. In Langfuse v4, read session data via `GET /api/public/v2/observations?filter=<urlencoded sessionId filter>&fromStartTime=<from>&toStartTime=<to>`. Self-hosted deployments are unaffected by this date; the endpoint becomes unavailable when they upgrade to Langfuse v4. See the [Langfuse v3 to v4 upgrade guide](https://langfuse.com/self-hosting/upgrade/upgrade-guides/upgrade-v3-to-v4). Get a session. Please note that `traces` on this endpoint are not paginated. For large sessions or new data extraction workflows, use the v2 observations endpoint with a URL-encoded `sessionId` filter and a bounded time range: `GET /api/public/v2/observations?filter=<sessionId filter>&fromStartTime=<from>&toStartTime=<to>`.
