A complete API platform for integrating Twelver into any coding workflow.

Pick Grok, Z.ai GLM, or Qwen per config. Twelver always maps to the best model in the series.
Real-time streaming responses for your coding agent.
Generate named API keys, track usage, revoke anytime.

Three steps to power your coding agent with Twelver.
Create a config below and pick your model series: Grok, Z.ai GLM, or Qwen.
Generate a named API key — it is only shown once, copy it now.
Set the base URL and API key in VS Code, Cursor, or Cline. Your agent is ready.
Open the chat with the question already typed and press send. The API Integrator answers with your own base_url, a fresh key, a ready config for your editor — and what it costs to run.
