Treg
OpenRouter for tools with 2,600 APIs, 0% markup
Treg is a tool registry that gives an AI agent one base URL and one token for roughly 2,600 catalogued endpoints across ~47 providers — SEO and backlinks, social and trends, people and company enrichment, ads, and scraping — with no provider signup required. Calls are billed per call at provider rates with the price shown before the call, starting from a fraction of a cent, and every new team gets $1.00 in free credit; there is no subscription. Teams can also register their own paid API accounts, OAuth connections, vendor CLIs and SKILL.md bundles, and the proxy relays the upstream request without modeling the response while injecting credentials server-side, so callers never hold a key. Built for developers whose agents need third-party data for one run at a time; self-hostable in Python (SQLite for dev, Postgres for production).
What is Treg?
Treg is a tool registry that lets an AI agent call third-party data APIs through one base URL and one token, without holding an account with any of the underlying vendors. The hosted catalog covers 2,630 endpoints across 47 providers — keyword and rank tracking, backlinks and authority, AI visibility, trending and discovery, social publishing, people and company enrichment, buying signals, ad campaign management, competitor creative analysis, and measurement — billed per call at the provider's own rate with $0.000 markup and the price shown before the call. Teams can also register their own paid API accounts, OAuth connections, vendor CLIs and SKILL.md bundles, and every credential is injected server-side so the calling agent never holds a key. It is source-available on GitHub and can be self-hosted.
Key features
- One unified treg token reaches 47 providers, and can be revoked in one place
- Catalog of 2,630 endpoints, callable on treg's own provider accounts with no signup at the vendor
- Per-call billing at provider rates with $0.000 markup and the price displayed before the call
- Tool selection driven by measured success rate and speed plus live pricing, rather than the agent guessing a vendor
- Credentials injected server-side and, in treg's wording, 'never on a machine'; OAuth supported for providers such as Google, Meta and LinkedIn
- Bring-your-own-key calls run unmetered — your own credential takes precedence over treg's
- Teams can register their own endpoints, vendor CLIs and SKILL.md bundles so every teammate's agent can call them without the secret leaving the server
- Source available on GitHub and self-hostable (the repo documents a Python + uv run serving on port 18790, SQLite for development and Postgres for production)
Who it's for
- Pulling keyword, rank or backlink data inside a single agent run without buying a Semrush or Moz subscription for it
- Enriching people and company records, or checking buying signals, from an agent workflow that does not justify a per-seat enrichment contract
- Giving a whole team's agents shared access to the team's registered vendor accounts, CLIs and skill bundles without distributing API keys to anyone's machine
- Running ad campaign management or competitor creative analysis from an agent through OAuth-connected Google or Meta accounts
- Letting an agent discover a tool by the task it needs done, rather than requiring the builder to know which vendor sells that data
When not to use it
If your agent only calls APIs you already hold accounts for, or if you need a direct vendor contract with an SLA and a data-processing agreement, Treg is a metered middleman and a single dependency sitting in front of roughly 47 vendors — go direct instead.
FAQ
How much does Treg cost?
There is no subscription. Calls against treg's catalog are billed per call at the provider's own rate with $0.000 markup, and the price is shown before the call — the site's published examples run from $0.004 per call for Hunter email verification through $0.006 for a Semrush keyword lookup and $0.012 for Moz backlinks up to $0.020 for Crunchbase funding data. Every new team starts with $1.00 in free credit. Calls routed through your own key are unmetered.
Does my agent have to hold the API keys?
No. Treg injects credentials server-side — the site states they are 'never on a machine' — and the proxy relays the upstream request without modeling the response. OAuth connections are supported for providers such as Google, Meta and LinkedIn, with tokens refreshed on treg's side. For catalog calls, treg carries the provider account itself, so you never sign up with the vendor at all.
Is Treg open source, and can I self-host it?
The source is on GitHub and self-hosting for your own organization is expressly permitted and documented. Be aware of a licensing discrepancy worth checking before you build on it: treg.to describes the project as '100% open source (AGPL)', while the repository's LICENSE file is Apache-2.0 plus Additional Terms that prohibit offering the software as a hosted, managed or embedded service to third parties without written authorization. That makes it source-available rather than AGPL. Read the repository LICENSE, not the marketing page.
What kinds of tools are in the catalog?
The catalog is organized by task rather than by vendor, and covers keyword and rank tracking (7 providers), backlinks and authority (4 providers), AI visibility tracking, trending and discovery across social platforms, social publishing, people and company enrichment, buying signals, ad campaign management, competitor creative analysis, and measurement and analytics.
