Developer Documentation

API Key Hub provides a unified, OpenAI-compatible API gateway that gives you access to models from OpenAI, Anthropic, Google, Mistral, and more through a single API key. No new SDKs needed -- just change your base URL.

Key Features

OpenAI-Compatible

Works with any OpenAI SDK. Python, Node.js, Go, or cURL -- just swap the base URL.

Multi-Provider Access

Access GPT-4o, Claude, Gemini, Mistral, and more models through one unified endpoint.

Pay-As-You-Go

No subscriptions. Recharge your balance and pay only for what you use.

Usage Tracking

Real-time spend tracking, budget limits, and rate limiting per API key.

Authentication

All API requests require an API key passed in the Authorization header using the Bearer token format:

Authorization: Bearer sk-your-api-key

You can create and manage API keys from your Dashboard. Each key has its own budget, rate limits, and model access controls.

Base URL

https://xylove.net/v1

All endpoints follow the OpenAI API format. If you are using an OpenAI SDK, set this as your base_url (Python) or baseURL (Node.js).

Rate Limits

Rate limits are applied per API key and depend on your plan. Each key has:

RPM (Requests Per Minute) -- maximum number of requests per minute
TPM (Tokens Per Minute) -- maximum number of tokens processed per minute
Budget -- maximum total spend for the key

When you hit a rate limit, the API returns a 429 status code with a Retry-After header. See the Error Codes page for details.
