Overview

treg is an open-source tool that aims to transform your coding agent into an SEO expert, media buyer, and SDR. It operates as a comprehensive catalog with a wide range of endpoints sourced from various providers and specialized in multiple areas like SEO, social, enrichment, and ads data.

Ease of integration signifies treg's operational model where a single credential per agent gives access to providers, eliminating the need for multiple sign-ups and scattered key files.

Your agent can choose the most suitable task not based on the tool, but on empirical evidence such as success rates, speed, and timing. This is because treg transparently displays each provider's costs and offerings, as well as our measured outcomes for their services.

Despite managing its own subscriptions, treg offers a flexible cost model where users are charged per call, with the cost showed prior to the call, and the possibility to use your own key for unmetered calls if you're already subscribed to a provider.

All of this without any additional fee; the user pays only the provider rate. Moreover, treg allows the listing of others' APIs or skills in their open-source catalog, hence providing a wider reach and versatile functionality.

The use of treg is as simple as one command in your agent, letting it handle jobs with its own identity and your keys, while providing a clearly defined bill.
