Quick answer

treg is a gateway that gives AI agents one key to more than 3,900 tool endpoints from 111 providers, including SEO data, enrichment, email finding, social data and ad libraries. Calls are billed per call from a prepaid balance at the provider's own rate with no markup, and new teams get $1.00 free.

treg gives an AI agent one key to a catalog of more than 3,900 tool endpoints from 111 providers: keyword and rank data, backlinks, AI visibility, social trends and posting, people and company enrichment, work-email finding and verification, ad libraries and more. Instead of buying a Semrush, Hunter or Crunchbase seat for one agent run, you top up a prepaid balance and each call is billed at the provider's own rate, with no markup and the price shown before the call. It works with Claude Code and other agents, and Value Add VC uses it to find and verify work emails for outreach drafts.

Why We Recommend treg

One Key for Every Tool

Your agent holds a single treg token and every tool in the catalog answers to it. No per-provider signups, no key files scattered across machines, and one place to revoke access.

A Catalog of 3,900+ Endpoints

Keyword volume and rank tracking, backlinks, AI Overview citations, TikTok, X, Instagram, YouTube and LinkedIn data, publishing to social networks, people and company enrichment, funding data, work-email finding and verification, and ad libraries for Meta, Google and TikTok.

Pay for Results, Not Seats

treg carries the subscriptions and bills fractions of a cent per call from a prepaid balance at each provider's own rate, with no markup. On per-success tools, a miss costs nothing. When the balance runs out, metered calls stop with a clear error instead of surprise charges.

Provider Comparison Built In

When several providers sell the same thing, such as nine for email lookup, treg shows what each charges and what it has measured them doing: success rate, speed and when they last answered. Your agent asks for the task and picks the provider on live data, or you pin a vendor.

Bring Your Own Keys and Skills

Register your team's provider keys and treg uses them instead of its own, unmetered. It can also turn your API keys and SKILL.md files into callable tools that teammates' agents use by token, while the key itself never leaves the gateway.

Works in Any Agent

Give your agent treg.to/llms.txt and it can set itself up. treg works with Claude Code and other agents through its CLI, API and MCP server.

Best For

Founders and operators running AI agents for SEO, outbound, research or social who don't want a dozen tool subscriptions

Teams that want agents to find and verify work emails or enrich leads for a fraction of a cent per call

Developers building agent workflows who want one key, clear per-call pricing and provider fallbacks

Anyone who already pays for a few providers and wants those keys plus the rest of the catalog behind one gateway

Pricing

Prepaid balance, metered per call (or per success where the provider bills that way) at the provider's own rate, with no markup, as listed on treg.to on October 13, 2026. New teams get $1.00 of free credit. There are no subscriptions, seats or monthly minimums. Calls on your own provider keys, your team's own tools and your connected accounts are never metered. Example rates start from fractions of a cent per call, for example about $0.004 to find a work email.

Our Verdict

treg is one of the most useful tools in an agent stack. One key gets your agent thousands of tools, from keyword data to verified work emails, and you pay the provider's own rate per call instead of paying for seats you would barely use. We use it at Value Add VC for email finding and verification in outreach drafts, and starting is free with $1.00 of credit.
