CreateActivate a plan
Complete checkout, sign in, and copy the API key from the dashboard.
From checkout to unmetered.
Create a key, set the compatible base URL, and keep working in the client you already use. Nothing meters what you send after that.

claudeCreate. Configure. Run.
ConfigureSet the host and key
Use environment variables or pass the OpenLimits base URL directly to your SDK client.
RunKeep your normal command
Open the tool or script you already use. Requests now arrive through the same OpenLimits key.
What happens after the request arrives.
The edge data plane carries the complete request and streams the provider response directly to the client.
Authentication and admission
The key, plan, model access, and request rate are checked before provider work begins. Nothing is billed per token — the check confirms entitlement, not budget.
Deterministic routing
An eligible route plan is created from provider policy, account state, and current capacity.
Streaming and accounting
Output streams to the client. Usage metadata is finalized for billing and dashboard analytics.
Use the setup path for your client.
Most clients need only a host and key. The guides cover the small differences in where those values go.
Claude Code
Reads the Anthropic base URL and auth token from your shell environment.
Cursor
Accepts the OpenLimits host and key from its model provider settings.
Anthropic SDK
Set base_url or baseURL when constructing the client.
OpenAI SDK
Use /v1/responses or /v1/chat/completions on the same host.
Configure it once. Use it all day.
