Unified APIs

This is the index of unified API service and tooling repos being tracked by the API Evangelist network. Unified APIs (also called integration hubs, API aggregators, or universal connectors) abstract multiple third-party APIs behind a single standardized interface, enabling software teams to build one integration instead of many. The market has grown to 23+ vendors in 2026, covering HR, accounting, CRM, file storage, ATS, e-commerce, and data pipeline use cases.

Unified APIs is profiled on the APIs.io network. Tagged areas include Aggregation, Normalization, Unified API, Integration, and Software-as-a-Service.

The Unified APIs catalog on APIs.io includes 1 JSON-LD context.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it.
