API Playground

OpenAI-compatible gateway at https://api.circuitnotion.com/v1. Need a key or credits first? Create a key or top up.

Testing ground

Try the API with your key

Paste an API key — we load models from GET /v1/models (same catalog Cline uses), then you can run a live chat completion against your wallet.

Example (key hashed)

curl "https://api.circuitnotion.com/v1/chat/completions" \
  -H "Authorization: Bearer $CIRCUITNOTION_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"circuit-2-turbo","messages":[{"role":"user","content":"Say hello in one short sentence."}]}'

Response

Run a request to see the assistant reply, model, and token usage.
