An opinionated Yellow Pages for AI agent stacks

What it does This repository is a curated catalog of third-party APIs for building autonomous systems. It organizes entries into three categories—Agents, AI Models, and MCP Servers—each linking out to provider documentation and pricing. The entire listing is rebuilt daily via a GitHub Actions workflow that pulls from the Apify catalog and discards anything outside those three buckets.

The interesting bit Instead of trying to index every API on the internet, the maintainer treats narrow scope as the product. The generated README tables and category counts are part of the repo itself, turning what could be a static spreadsheet into a browsable launchpad.

Key highlights

• 2,920 APIs tracked across Agents (879), AI Models (1,603), and MCP Servers (438)
• Daily auto-sync via GitHub Actions, committing only when upstream Apify data changes
• Explicit scope guarantee: anything outside the three agentic categories is removed
• README layout and metrics tables are auto-generated and version-controlled
• Disclosed affiliate tracking on outbound API links

Caveats

• The repo description advertises 2,036 APIs, while the README claims 2,920—the counts do not match
• This is a link directory, not an installable package or framework
• Outbound links carry affiliate tracking from the upstream data source

Verdict Useful as a filtered starting point if you are researching agent infrastructure and want to avoid generic API junk drawers. Not for you if you need a programmable SDK or drop-in library.
