A resource tag, not a market

No company describes its business as “.well Known”. It names something an API does — and 99 providers reach it through a specification or operation tag. The APIs below are the answer to this tag; the companies are not.

Providers using this tag (0)

No company classifies itself here — see the resource-tag note above, and the APIs below.

APIs with this tag (97)

Ranked by the provider's API Evangelist rating — the Kin Score is scored per provider, not per API, so every API of a provider shares its band. How the rating works →
