Treg (OpenRouter for Tools)

OpenRouter, but for agent tools instead of models. Point an agent at one base URL with one token and it can do the job: 3,000+ catalogued endpoints across 60+ providers — SEO and backlinks, social and trends, people and company enrichment, ads, scraping, image and video generation — priced per call, from a cent, with no provider signup. Plus your own team's keys, skills and CLIs, callable by every teammate's agent without the credential ever leaving the server.

Ask for the task, not the tool. You do not need to know which vendor sells backlink data, or to hold an account with them. Search for what you want to do, read the price, call it.

Built for the Superdesign team, live at treg.to — anyone can self-host.

Why it exists

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, or behind no public API at all (invite-only, partner-only, app-review-only). treg carries those accounts and bills fractions of a cent per call.

Two kinds of tool, one token

route that needs no provider key. Own-key calls use the team's prepaid balance; anonymous calls are free. No account with the provider is needed. New verified accounts receive $1.00 free once, when they create an eligible team.

• The catalog — external endpoints treg can serve with its own key or through a verified public

vendor CLI, a SKILL.md. Your own key always wins over treg's, and those calls are never metered.

• Your own tools — anything a teammate registered: a paid API account, an OAuth connection, a

The vocabulary for the second half:

secret into the request; a request can carry several, e.g. an OAuth bearer and a developer-token header).

• tool = something the registry calls for you with the org's credential. Two kinds:
• endpoint — an upstream baseurl + credential bindings** (each binding injects one

• CLI — a vendor binary (stripe, gh, vercel, ...) run with the credential injected.
• skill / bundle = a recipe (SKILL.md) + its secrets + its tool(s), registered together.

The one rule: the proxy relays, never models the upstream, and injects auth server-side — so it survives upstream API changes and callers never hold keys.

Part 1 · Using the registry

Visit treg.to (hosted on Render) — the dashboard, sign-in, and every URL below live there.

Quickstart

Same flow as the dashboard's Getting started guide:

# 1. install the CLI — also points it at the registry
curl -fsSL https://treg.to/install.sh | sh

# 2. sign in (GitHub default · --email for a one-time code · --token for agents/CI)
treg login

# 3. do something useful immediately — no key, nothing registered
treg catalog search "backlinks for a domain"     # find a tool by what it DOES
treg call tikhub.tiktok.user.profile --query uniqueId=tiktok
treg balance                                     # exactly what that cost

# (or `treg onboard` for the guided walkthrough)

Catalog tool inputs are described by treg catalog get . Tools marked strict_query reject undeclared or repeated query parameters, unsupported values and request bodies.

Your token identifies you on every call (X-Treg-Token header) and is the same for all tools. Discover what your team has shared: treg tool ls · check credential health: treg health.
