Open-source AI gateway for LLM APIs, agents and MCP servers
Route requests to 100+ model APIs through unified protocol conversion, with model-level fallback and flexible backend scheduling.
Expose existing services as MCP servers, proxy and translate protocols, and apply authentication, traffic scheduling and parameter mapping to tool calls.
Track token consumption per consumer, enforce quotas on overuse, and cache exact or semantically similar answers to save tokens and reduce latency.
Protect privacy on data sent to external models and filter model output before it reaches users, alongside standard gateway auth and rate limiting.

One key for 4,100+ agent tools, pay per call
A single treg token routes to 4,100+ endpoints across 127 providers, so no per-provider signups or scattered key files.
See each provider's price plus measured success rate, speed, and last-answer time, and pin a preferred vendor when you want.
Pay fractions of a cent per call with the price shown before you commit, no monthly seats required.
Route calls through your existing provider keys at no markup; credentials are injected server-side and never stored on a machine.
