LLM Gateway API key setup
Open-source API gateway for LLMs. Route requests to 180+ models from 60+ providers with one integration. Self-hostable with usage tracking and cost optimization.
Disclosure: the sign-up link in step 1 is a partner link. Dracon may earn a commission when you create an account through it. It never changes the price you pay, and LLM Gateway's own site is always reachable directly at llmgateway.io.
Get your key
- Open the LLM Gateway site: llmgateway.io/?ref=SVEujbA3OheTzE8xKe7E partner link
- Create an account and generate an API key.
- Paste it into the Dracon BYOK provider keys, stored encrypted (AES-256-GCM), used browser-direct, works in every Dracon tool.
Use your key in every tab
Two free extensions take the key you just set up. Both read the page you are on and use your own provider key: free, no account, nothing stored on a server we run.

Gotchas
Browser-direct chat is not available for this provider: We haven't verified its chat endpoints yet.. Dracon provider keys still cover it for tools that run elsewhere (for example a LiteLLM chain from the Dracon Router builder).
