OpenTelemetry
Vendor-neutral open-source observability framework for cloud-native software, providing a collection of tools, APIs, and SDKs for instrumenting, generating, collecting, and exporting telemetry data including metrics, logs, and traces.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles OpenTelemetry the way a machine reads it — 12 machine-readable artifacts across 6 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 — OpenTelemetry scores 57.9/100 (developing), with a separate agent-readiness read of 30/100 (agent aware). 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.

How we profile OpenTelemetry
Each block below is one kind of artifact we hold for OpenTelemetry. 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 6
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.
OpenTelemetry Protocol (OTLP) gRPC API
The OTLP gRPC API defines Protocol Buffers service definitions for exporting traces, metrics, and logs over gRPC. It is the primary transport for OpenTelemetry data between SDK ...
OpenTelemetry Collector API
The OpenTelemetry Collector is a vendor-agnostic proxy for receiving, processing, and exporting telemetry data. It exposes HTTP and gRPC endpoints for receiving OTLP data and pr...
OpenTelemetry SDK API
The OpenTelemetry SDK API specifies language-level interfaces for instrumentation, including the Tracer, Meter, and Logger APIs used by application code to create spans, record ...
OpenTelemetry Logs API
The Logs API from OpenTelemetry — 1 operation(s) for logs.
OpenTelemetry Metrics API
The Metrics API from OpenTelemetry — 1 operation(s) for metrics.
OpenTelemetry Traces API
The Traces API from OpenTelemetry — 1 operation(s) for traces.
Pricing 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 six things the Kin Score reads for commercial clarity.
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.

RATE LIMITSFinOps 1
Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

FINOPSEvent Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.
AsyncAPI definitions for this provider's event-driven and streaming APIs.
OpenTelemetry Protocol (OTLP) Telemetry Events
The OpenTelemetry Protocol (OTLP) defines the event-driven telemetry export pipeline through which instrumented applications and OpenTelemetry Collectors push batches of traces,...
ASYNCAPISpectral Rules 1
Governance rulesets we run against this provider's specs — the automated checks behind parts of the score. Profiling them makes the quality bar explicit and re-runnable, not a matter of opinion.
OpenTelemetry API Rules
SPECTRALSecurity Posture 1
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.
