SlashID

SlashID is a developer-first identity platform that provides REST APIs for passwordless authentication, multi-factor authentication, passkeys, and comprehensive user management across web and mobile applications. The platform offers three core modules: Identity Management for building authentication and user lifecycle flows, Identity Protection for monitoring and remediating security events across human and non-human identities, and Gate for identity-based traffic authorization at the API and workload edge. SlashID supports multiple authentication factors including magic links, biometrics, TOTP, and SSO, with global availability and an event-driven architecture. The service publishes an OpenAPI 1.1 specification and offers JavaScript, React, and Remix SDKs alongside API-key and OAuth2/OIDC authentication.

SlashID publishes 7 APIs on the APIs.io network, including Identity Management API, OIDC discovery API, Organization SSO config API, and 4 more. Tagged areas include Identity, Authentication, Passwordless, MFA, and Passkeys.

The SlashID catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

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/slashid: open an issue to ask a question, or submit a pull request to add artifacts.
