Auth through Squiid
User authentication and identity: hosted sign-in, social login, passkeys, multi-factor, sessions, organizations and enterprise single sign-on. They own the part of your app most likely to be got wrong by hand.
Who needs this
Any product with accounts, especially B2B apps that will be asked for SAML or SCIM later.
Squiid lists 4 auth services: 1 live today, 0 next up and the rest on the roadmap. Each one is reachable at https://api.squiid.io/v1/<service-slug>/ with the header Authorization: Bearer $SQUIID_API_KEY, and official SDKs work by pointing their base URL at the gateway (gateway convention).

One key, not six
Your .env holds SQUIID_API_KEY and nothing else. Squiid holds the provider keys, so nothing sensitive reaches your repository, a preview deployment or an agent’s context window.
One bill, no markup
Usage is metered at the provider’s list price against prepaid credits, and subscriptions pass through at the provider’s price. Squiid adds no markup to provider prices. There is a free plan at $0 a month with a 15% fee when you top up credits, Solo at $19.97 a month with a top-up fee that starts at 8% and falls to 3.5% as your spend grows, Team from $29.97 a seat a month with the same ladder one point lower, and Custom with a rate of 3% or less.
Spend that stops
Every call is metered per service in one dashboard, and when credits run out the gateway stops authorizing usage instead of producing a bill you did not fund.
Questions people ask
Which auth services can I use through Squiid?
4 of them: Auth0, Clerk, Stytch, WorkOS. 1 is live today, 0 are next up, and the rest are on the roadmap. All of them run on the same SQUIID_API_KEY.
Does Squiid mark up auth pricing?
No. Provider usage is billed at the provider’s list price against your prepaid credits, and subscriptions pass through on the monthly Squiid invoice with no fee. Squiid earns from your plan and the percentage taken when you top up credits.
Can Claude Code and Cursor use these through one key?
Yes. Requests go to https://api.squiid.io/v1/<service>/ with an Authorization: Bearer $SQUIID_API_KEY header, and official SDKs work by pointing their base URL at the gateway. Every agent, from Claude Code and Cursor to Codex, Windsurf and Cline, uses the same single variable.
