Summary
treg is an open-source API gateway for AI agent tools, analogous to OpenRouter but for tool endpoints instead of LLM models. It aggregates 3,000+ endpoints across 60+ providers (SEO, enrichment, scraping, ads, etc.) behind a single base URL and token, eliminating the need for individual SaaS subscriptions.
Highlights
- Solves the problem of agents needing access to expensive SaaS tools (Semrush $139/mo, Moz $99/mo, Crunchbase $99/mo) by metering access per call from a fraction of a cent
- Supports two tool types: catalog endpoints served on treg's own key (metered against prepaid balance) and user-registered tools (own keys, never metered, always take priority)
- Core design principle: the proxy relays and injects auth server-side, never models the upstream, so it survives API changes and callers never hold credentials
- Supports endpoints, vendor CLIs (stripe, gh, vercel), and skill bundles (SKILL.md + secrets + tools) as first-class tool types
- Open source and self-hostable, with a hosted instance at treg.to; $1.00 free credit for new verified accounts
