Caterpillar

Caterpillar Inc. (NYSE: CAT) is the world's leading manufacturer of construction and mining equipment, off-highway diesel and natural gas engines, industrial gas turbines, and diesel-electric locomotives. Its digital arm, Cat Digital, publishes developer APIs through the Cat Digital Marketplace (digital.cat.com) covering fleet, asset, fuel, and worksite telematics built on top of the Cat Connect and VisionLink data platforms. The callable surface runs on an Apigee gateway at services.cat.com (mirrored at api.cat.com) and is authorized by a PingFederate OAuth 2.0 / OpenID Connect authorization server at fedlogin.cat.com. Caterpillar implements the ISO 15143-3 (AEMP 2.0) mixed-fleet telematics standard, so a consumer that already speaks AEMP can read Cat machine data with no bespoke connector.

Caterpillar publishes 2 APIs on the APIs.io network: ISO 15143-3 (AEMP 2.0) API and VisionLink APIs. Tagged areas include Construction, Engines, Fortune 500, Heavy Equipment, and Locomotives.

Caterpillar’s developer surface includes authentication, changelog, developer portal, documentation, API reference, getting-started guide, support, and 32 more developer resources.

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.

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. This rating is computed from github.com/api-evangelist/caterpillar: open an issue to ask a question, or submit a pull request to add artifacts. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →
