Heap scores Band C on The Headless Index. Its JAIRF rating is not available because no machine-readable spec was scored. Its strongest area for agent use is API-first design intent; its weakest is MCP and agent posture.

Does Heap publish an OpenAPI spec?

No published OpenAPI specification was found when Heap was scored. That caps its JAIRF dimensions and forces agents to rely on documentation or reverse engineering to operate it.

What is Heap's Headless Index score?

Heap scores 41/100 on the Headless Index thesis-fit rubric and sits in Band C in the Analytics & Events category. The score weighs API-first design, headless operation, MCP and agent posture, schema observability, and webhooks.

Heap earns Band C in the Analytics & Events category of The Headless Index, with a thesis-fit score of 41/100. Its strongest dimension is API-first design intent (15/20); its weakest scored dimension is MCP and agent posture (0/20). No public OpenAPI specification was found when Heap was scored, which limits how far an agent can go without human integration work.

Editorial verdict

Heap is partially headless and partly UI-led. The Headless Index thesis-fit score of 41/100 puts it mid-table on the index, and JAIRF is recorded as N/A for this vendor because no public OpenAPI specification was reachable for the open-source scorer. In practice, vendors at this tier are partly machine-consumable: the core flows are reachable through code but several adjacent surfaces still expect a human at a dashboard, and the rest of this verdict explains where Heap lands inside that pattern. On the API surface, the question is whether the API is the product or a layer beneath the dashboard. Heap (now Contentsquare-owned) is product analytics with autocapture as the differentiator. REST API for users, events, sessions, and reports. SDKs in JavaScript, iOS, Android, and server-side languages. The autocapture model reduces the API surface that integrators interact with directly.^[1] Schema observability is the related test: can an agent introspect the contract from cold, or does it have to read prose documentation to do so? REST documented at developers.heap.io. Schema discoverability is medium for autocapture-driven analytics.^[2] An agent can drive parts of this product, but not all of it: integrators should plan for human-in-the-loop checkpoints where the headless surface stops short. On headless operability: Properties, events, cohorts, segments, and accounts are programmable. The Heap dashboard handles configuration. Autocapture model means less programmatic instrumentation work for typical use cases.^[3] On the MCP and agent-integration axis, which is the fastest-moving criterion in the index: No first-party Heap MCP server. The Contentsquare acquisition has not yet extended to MCP integration.^[4] Event posture closes the loop: an agent that cannot react to state changes is reduced to polling. Heap webhooks deliver event notifications and segment sync. Catalog is appropriate for autocapture-driven product analytics. Net assessment: integrators can build agent flows against Heap, but the rough edge to plan around is MCP posture^[5]. Expect to wrap missing pieces in bespoke glue or accept human-in-the-loop checkpoints. Workable but requires scaffolding.
