Get from login to a working API key.
Use the hosted endpoint for OpenAI-compatible clients, keep local and bring-your-own-provider routing available, and manage billing from one account.
sk_sage_* key./v1/models through the public edge.Sign up
No provider key or credit card is required until your generated sk_sage_* key exists. Sign in by email, create the key first, then complete checkout to unlock routing.
Enter your email to receive the API key setup link for the selected plan.
Fastest path: continue with an enabled OAuth provider, or enter your email and use a magic link. Password sign-in is available when you need it.
Pick a hosted plan first
Selection is saved in this browser and used after sign-in for checkout.
Account
Loading...
Create an API key, verify it against the public edge, then send the first routed request.
Launch checklist
This tracks the generated-key to first routed request funnel for the hosted API path. Browser verification proves the key reaches /v1/models; completed usage proves a routed request was recorded.
Sign in so API keys and billing attach to your account.
Create at least one active sk_sage_* key.
Choose Lite, Pro, or Max so generated keys can route production traffic.
Use the verifier below to check /v1/models before wiring an agent.
Run the browser Responses API probe and refresh usage after it succeeds.
Post-key activation
After creating an sk_sage_* key, keep the next conversion step visible: verify /v1/models, send the first sage-router/frontier request, or copy Codex setup.
Safe support context
Copy bounded account, plan, quota, and activation state for support. This packet does not include prompts, provider credentials, OAuth tokens, generated API keys, private keys, cookies, raw provider responses, or customer data.
Usage
Loading current billing period...
Generate API key
Create the key first so setup can be copied immediately. Checkout unlocks routing for generated keys after payment.
Use the endpoint
OPENAI_BASE_URL=https://api.sagerouter.dev/v1
ANTHROPIC_BASE_URL=https://api.sagerouter.dev
Provider coverage depends on the account plan and backend provider credentials. Bring-your-own-provider pass-through remains supported by router configuration.
Choose plan
Checkout uses the selected plan. The API keeps generated keys blocked from paid routing until the account is active, trialing, or manually enabled.
OpenAI-compatible quickstart
After creating a key, send a first hosted Responses API request from this browser or copy the command for your own shell.
Client setup
Copy the setup for the client you are wiring. Generated keys are inserted after key creation and are only stored in this browser session.
OpenAI SDK
Codex CLI
Verify API key
Check the public edge with /v1/models before wiring an agent. This uses your generated key only in this browser session.
