+[Base endpoint URL](https://opentelemetry.io/docs/languages/sdk-configuration/otlp-exporter/#otel_exporter_otlp_endpoint) for all signal types: `http{s}://<host>/v1/otlp`
+
+This unified endpoint is useful when sending multiple signal types (metrics, logs, and traces) to the same destination, simplifying your OpenTelemetry configuration.

 ## Metrics
 
 GreptimeDB is an observability backend to consume OpenTelemetry Metrics natively via [OTLP/HTTP](https://opentelemetry.io/docs/specs/otlp/#otlphttp) protocol.
