Loki HTTP API is one of 3 APIs that [Grafana Loki](https://apis.io/providers/grafana-loki/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Logs, Logging, Observability, LogQL, and OpenTelemetry. The published artifact set on APIs.io includes API documentation, an API reference, and a getting-started guide.

The Grafana Loki HTTP API — 40 documented endpoints for pushing logs (native and OTLP), querying with LogQL over instants and ranges, discovering labels, series, patterns and detected fields, streaming a live tail over WebSocket, managing Prometheus-shaped alerting and recording rule groups, submitting and cancelling log deletion requests, and reading component status and ring state. Loki is self-hosted software, so the base host is whichever address the operator binds; the documented default port is 3100 and TLS is terminated by the operator or a fronting proxy. Authorization is explicitly not part of this API.
