treg is a proxy that lets AI agents call a curated catalog of thousands of endpoints across many providers through a single base URL and token, with per-call pricing. The proxy relays upstream requests and injects credentials server-side, so callers never hold provider keys.
Project overview
treg addresses a concrete blocker for agent workflows — per-vendor subscriptions, signup walls and credentials — by centralizing authentication server-side behind one base URL and one token, and it can be self-hosted or run from Python or source in addition to the hosted registry.

Best for
Developers and AI engineers who need agents to call external tools without managing a provider account and credential for each one.
Teams that want to share endpoints, CLI credentials and SKILL.md skill bundles so every teammate's agent can call them.
Key capabilities
Relays a curated catalog of thousands of endpoints across providers, priced per call, injecting credentials server-side so callers never hold keys.
Command-line tool to search the catalog by task, call tools, check balance and health, and audit calls.
Scan and upload team endpoints, CLI credentials and SKILL.md skill bundles to the registry, encrypted server-side and callable by every teammate's agent.
Limitations and risks
The license restricts redistributing the code as a competing hosted or managed registry service without written permission; review this before adopting it for any hosted offering.
Endpoints with no published price are refused rather than served free; confirm the endpoints you need are priced in the catalog.
Catalog calls through the hosted registry go to treg.to with prepaid balance billing, so the hosted path is not local-only; data boundary is external and optional, with self-hosting available.
Getting started
Setup difficulty is rated easy and no coding is required to get started; the CLI supports searching the catalog by task, calling tools, and checking balance and health.
Evidence and sources
README: Point an agent at one base URL with one token and it can do the job: **a curated catalog of thousands of endpoints across many providers**
README: The tools an agent needs for real work sit behind subscriptions nobody buys for a single run — Semrush $139/mo, Moz $99/mo, Crunchbase $99/mo, Apollo $59/seat — behind signup walls
README: the proxy **relays, never models** the upstream, and **injects auth server-side** — so it survives upstream API changes and callers never hold keys.
