Supports OpenAI, Alibaba Qianwen, Moonshot, DeepSeek, and any OpenAI-compatible endpoint. Just paste your API key and go.

See response content, latency, HTTP status, and token usage at a glance — everything you need to validate a model before integrating.

Switch to HTTP mode to send arbitrary GET/POST requests with custom headers and body — no install needed.

API keys are stored only in your browser's local storage and never sent to our servers. All requests go directly to the provider.
