test.ai
test.ai (formerly Appdiff, Inc.) built an AI-powered test-automation platform that used computer vision and machine-learning element classification to make Selenium and Appium tests resilient to UI change. It published first-party Java, Python, Node.js and Ruby SDKs, a gRPC "Classifier" service that labelled UI elements from screenshots, an Appium classifier plugin, and OpenTestData — a free open database of automated test fixture data with its own REST API. The company raised over $30M and was sold; its founder has since moved on to other ventures. As of 2026-08-30 test.ai serves no website of its own: the domain has no HTTPS listener and every HTTP path redirects off-domain. The artifacts profiled here are the contracts and packages the company published while operating, all of which remain publicly retrievable from its own GitHub organization and from the npm, PyPI, RubyGems and Maven Central registries.
test.ai publishes 6 API contracts indexed on the APIs.io network, including Data API, Ping API, Search API, and 3 more. Tagged areas include Company, Testing, Test Automation, Quality Assurance, and Artificial Intelligence.
The test.ai catalog on APIs.io includes 1 Spectral governance ruleset.
test.ai’s developer surface includes documentation, getting-started guide, and 13 more developer resources.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| ONVIF Video Analytics (video surveillance, edge cameras, computer vision) | undeclared | - | - | - |
| Buf Schema Registry (public Protocol Buffers modules, gRPC / ConnectRPC schema publishers) | undeclared | - | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards implemented 2
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
APIs 6
