APIs.guru / One provider's APIs and OpenAPI spec links

Returns the APIs one provider publishes in the APIs.guru OpenAPI directory, by provider domain (e.g. stripe.com): for each API its title, description, categories, current version, the source spec it was taken from (x-origin), when it was added and updated, and the URLs of its OpenAPI definition in JSON and YAML (swaggerUrl, swaggerYamlUrl). Use developer.api.providers for the list of provider domains. An unknown provider answers 404, a miss. Licence: definitions contributed by API authors are CC0 1.0; the info text (description, contact, terms link) and any spec copied from a vendor's public source are used under fair use and stay under the vendor's own terms (https://github.com/APIs-guru/openapi-directory#licenses).
