OpenAI-Compatible API Tester

What the OpenAI-Compatible API Tester does

The OpenAI-Compatible API Tester sends a chat completion request to any compatible endpoint and shows the raw JSON response. Enter a base URL, model ID, API key and test message, and the page posts to /chat/completions with a small token limit. It is built for developers verifying a new key, base URL or model name before writing integration code. The default target is Plugsky's endpoint with plugsky-micro. Keys are sent from your browser to the endpoint you enter.

How to use it

1. Open the OpenAI-Compatible API Tester.
2. Enter the base URL, such as https://plugsky.com/v1.
3. Enter the model ID you want to test.
4. Paste an API key and type a short test message.
5. Click Send test request and inspect the JSON response.

FAQ

Is it safe to paste an API key?

The key is sent from your browser directly to the endpoint you specify, not stored by the page. Use a test key where possible and rotate any key you consider sensitive afterward.

What endpoint does it call?

It calls your base URL plus /chat/completions with a JSON body containing the model, one user message and a small max_tokens value, matching the OpenAI chat completions format.

Why does my request fail?

Common causes are a missing /v1 in the base URL, a wrong model ID, an invalid key or browser CORS restrictions on the endpoint. Check each in turn before debugging your application code.
