Chartbeat
Chartbeat is a real-time content analytics and audience-engagement platform built for digital publishers, media brands, and editorial teams. It measures how audiences read, watch, and engage with content the moment it is published, reporting live traffic, engaged time, loyalty, video engagement, and headline performance. Beyond its dashboards, Chartbeat exposes public HTTP APIs: a Real-Time API for live traffic and video data updated every three seconds, a Historical (Advanced Queries) API for summary traffic reporting, and Headline Testing, Conversion, and Data Lab APIs, plus JavaScript, iOS, Android, and React Native tracking SDKs for data collection. Authentication is via an account API key sent in the X-CB-AK header.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Chartbeat the way a machine reads it — 8 machine-readable artifacts across 5 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 — Chartbeat scores 33.4/100 (thin), with a separate agent-readiness read of 20/100 (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 Chartbeat
Each block below is one kind of artifact we hold for Chartbeat. 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 5
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.

Chartbeat Conversion API
Retrieve the top articles that drove a given conversion event for a specified host and date range, with counts attributed per path.
Chartbeat Data Lab API
Programmatic access to Chartbeat Data Lab datasets for deeper custom analysis of audience and content performance.
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 LIMITSSecurity Posture 2
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.
