Treg

Treg is an open-source agent tool catalog and unified API gateway that gives coding agents access to thousands of endpoints covering SEO, AEO, social media, data enrichment, advertising, e-commerce, reviews, scraping, AI generation, communities, developer services, and market data. Instead of juggling a dozen provider dashboards, your agents discover and connect to every tool they need from a single, searchable catalog.

Provider credentials are centralized server-side, so keys stay out of your codebase and out of your agents' hands. When multiple providers offer the same capability, agents can select tools based on price and performance, automatically choosing the option that best fits the task at hand.

Treg also supports bring-your-own keys if you already have accounts with specific providers, and billing is usage-based: you pay per call or per result rather than committing to separate provider subscriptions. That means you can experiment freely, scale only what you actually use, and keep every integration managed in one place.
