What is treg?

treg is an open-source agent-tool registry designed to help coding agents discover and call a catalog of external endpoints. It focuses on SEO, research, social, enrichment, advertising, and scraping use cases. The platform provides a single treg credential for catalog access, while also supporting users’ own provider keys or connected accounts.

Key Features

  • Searches and compares a catalog of thousands of agent-callable endpoints across dozens of providers
  • Lets agents use one treg credential instead of managing separate vendor registrations and key files
  • Shows per-call catalog pricing so users can review provider rates before using endpoints
  • Supports catalog usage billed from a prepaid balance
  • Routes users’ own provider keys or connected accounts without metering, according to the provided tool information
  • Offers open-source self-hosting for teams that want more control over deployment
  • Provides CLI, skills, and API-oriented integrations for agent workflows
