Question 1

Does SigID charge by monthly active users (MAU)?

Accepted Answer

No. SigID does not bill by user count. Human login, passkey login, wallet sign-in, consent views, OIDC discovery, JWKS reads, and token revocation are free.

Question 2

What are Auth Credits?

Accepted Answer

Auth Credits meter higher-value identity operations such as AI agent authentication, token exchange, delegated access, introspection, wallet policy authorization, and signing.

Question 3

How do I integrate SigID?

Accepted Answer

Create an application in the SigID dashboard, register exact redirect URIs and scopes, redirect users to hosted auth with Authorization Code and PKCE, exchange the callback code at the discovered token endpoint, then validate SigID tokens on every protected backend route.

Question 4

How do AI agents authenticate with SigID?

Accepted Answer

Agents are first-class principals. They register themselves with a key pair and an anchor proof (ERC-8004, did:web, or did:key), authenticate via cryptographic challenge-response, and receive the same standard OAuth 2.1 and OIDC tokens as human users.
