Grafana Loki
Grafana Loki is Grafana Labs' open source log aggregation system — "like Prometheus, but for logs." Rather than full-text indexing log contents, Loki indexes only a small set of labels per log stream and stores the compressed lines in object storage, which is what makes it cheap to run at scale. It is queried with LogQL, a Prometheus-inspired query language, over an HTTP API that covers ingestion, querying, label and pattern discovery, live tailing over WebSocket, a Prometheus-compatible ruler for alerting and recording rules, and a cancellable log deletion API. Loki accepts native pushes and OpenTelemetry OTLP/HTTP logs, publishes proto3 gRPC service definitions for its push and query paths, and ships a first-party CLI (LogCLI), Helm charts, a Kubernetes operator, and Docker images. It is licensed AGPL-3.0 and self-hosted; the same engine is sold as the managed Grafana Cloud Logs service and as the self-managed Grafana Enterprise Logs distribution.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles Grafana Loki the way a machine reads it — 11 machine-readable artifacts across 3 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Grafana Loki scores 62.5/100 (strong), with a separate agent-readiness read of 45/100 (agent native). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Grafana Loki
Each block below is one kind of artifact we hold for Grafana Loki. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 3
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Loki HTTP API
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 de...
Grafana Cloud Logs API
Grafana Cloud Logs is the fully managed Grafana Loki service. It serves the same Loki HTTP API on a per-stack host of the form logs-prod-
Grafana MCP Server — Loki tools
Grafana Loki reaches MCP clients through the Grafana Labs MCP servers, which register a Loki tool family (query_loki_logs, list_loki_label_names, list_loki_label_values, query_l...
MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Grafana MCP server (Loki tools)
Grafana Loki does not itself ship an MCP server. The Loki query surface reaches MCP clients through the Grafana Labs MCP servers, which expose Loki as a datasource: the open-sou...
MCP SERVERPricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

SECURITYScopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.

This is an independent, third-party profile of Grafana Loki, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
