OpenRouter for tools and data for Agents, Pay-per-call, One key for enrichment, SEO, social and ads, Open source
treg is a tool gateway for AI agents, letting developers connect an agent to 3,900+ endpoints across 111 providers through one MCP server and a single key. It covers keyword and rank data, backlinks, AI visibility, social trends and publishing, people and company enrichment, ad campaigns and measurement. Instead of buying seats from Semrush, Moz, Hunter or Crunchbase, users pay per call at the provider's own rate with no markup, with the price shown before each call. The catalog lists measured success rate and speed so agents can pick providers on evidence, and users can bring their own keys. It is open source under AGPL, with $1.00 free to start.
