Quickstart

OctaRouter gives you one account for every major LLM: register, create an API key, then point any AI app, agent, or backend at OctaRouter's base URL + key. Swap models by changing the model ID — no new vendor sign-ups or keys.

How OctaRouter works: requests are forwarded to upstream providers in a compatible shape. Use OctaRouter's base URL and your API key; follow the official OpenAI, Anthropic, or Google docs for all request and response parameters.

Steps

1. Sign up at OctaRouter and verify your email.
2. Open Dashboard → API keys and create a key. Copy the secret immediately — it is shown only once.
3. Open the Models page:
   • Copy the model ID from the card (use it in the model field or Gemini URL path).
   • Click a protocol badge on the card to copy the matching base URL.
   • If unsure, pick OpenAI-compatible — it works for almost every model.
4. Send a request:

curl "https://api.octarouter.com/v1/chat/completions" \
  -H "Authorization: Bearer sk-or-..." \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4o-mini",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

Replace sk-or-... with your API key and use the model ID from the Models page.

The OpenAI-compatible route (POST /v1/chat/completions) is the default for most clients. Claude and Gemini also support native protocols — see API protocols for base URLs, examples, and links to official docs.

To switch models later, keep the same OctaRouter base URL and API key; change only the model ID.
