A resource tag, not a market

No company describes its business as “Sign Up”. It names something an API does — and 48 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 (47)

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 →

Exemplar 4 Complete, well-documented, and agent-ready
Strong 9 Solid coverage with minor gaps
Developing 14 Usable, with meaningful gaps to close
Thin 14 Limited public surface area
Emerging 6 Early or largely undocumented

Companies reaching this through an API (48)

These companies publish an API, specification or operation carrying “Sign Up” but do not classify their business under it. Listed unranked and kept out of the count above, because one tagged operation is not a statement about what a company does.
