A community-managed OpenAPI spec for the (excellent) Diffbot API.
Unfortunately, Diffbot does not appear to publish a public OpenAPI spec. However, with a little coaxing, it's possible to extract a (generally) OpenAPI spec-shaped object from its documentation platform. (The curious can check the Makefile to see how this is done.) This project simply pulls down that OpenAPI-shaped object, massages it into compliance with v3.0.x of the OpenAPI spec, and makes releases available for general download.
The spec itself may be found under the "releases" section of this repo.
At this time, the author only requires the extract endpoints. Therefore, only the extract endpoints are currently supported. However, the process to add more endpoints is described in the Makefile, and all PRs are welcome.
Naturally, if at any point Diffbot should release an OpenAPI spec publicly, users should immediately prefer that spec. In the meantime, hopefully this will do nicely. If I become aware of any official OpenAPI spec, I'll be sure to link it here. This repo will stay up regardless, for reliability.
