What is an LLM gateway?
An LLM gateway is a service that sits between your application and multiple large language model providers, giving you one API endpoint, unified billing and simpler routing.
The problem it solves
Teams that use more than one AI provider end up managing separate API keys, SDKs, rate limits and invoices. An LLM gateway replaces that complexity with a single endpoint and one set of credentials.
Core capabilities
A typical gateway handles request routing, model selection, load balancing, retry logic, rate limiting, cost tracking and sometimes caching or prompt guardrails. You call one API and the gateway forwards the request to the right model.
Why developers use one
Developers use an LLM gateway to swap models without rewriting integrations, to route traffic to cheaper or faster models for specific tasks, and to centralize observability and spend management.
How TokenGate fits in
TokenGate is an LLM gateway with a crypto-native twist: one OpenAI-compatible endpoint, access to OpenAI, Anthropic, Google, DeepSeek and xAI models, and payment in USDT through a connected wallet.
