OpenAI-Compatible Clients

Any client that accepts a custom OpenAI base URL, API key, and model ID can usually connect to Sprelay.

Possible field label	Value
Provider Name	Sprelay API
API Key / Token	A dedicated Sprelay key
Base URL / API Base	https://sprelaytoken.com/v1
Model / Model ID	An exact ID from the live catalog

Use the example shown beside the client's field to determine the URL depth:

• If the example ends in api.openai.com/v1, use https://sprelaytoken.com/v1.
• If it ends in api.openai.com, use https://sprelaytoken.com.
• If the field explicitly asks for a Chat Completions endpoint, use https://sprelaytoken.com/v1/chat/completions.

For the first test, disable web search, knowledge bases, tools, and images. Start a blank chat, select one available chat model, and ask it to reply only OK. Restore advanced features one at a time after that succeeds.

Check whether the third-party client stores keys locally or syncs them to its own servers. Use a low-quota, model-restricted key whenever the storage behavior is uncertain.
