About Agenex

The neutral registry and price comparison engine for agent-payable APIs.

The problem

AI agents can now pay for services autonomously — via x402, Stripe ACP, Google AP2, and other emerging protocols. But there's no central place to discover what's available, compare prices, or trust that a service is actually reliable.

What Agenex does

Agenex is a registry of agent-payable APIs. We track:

Per-endpoint pricing across protocols (x402, Stripe ACP, and more)
Live uptime and latency — pinged every 5 minutes
Price history — so you can see if a service raised its prices
Developer reviews with verified usage badges

For AI agents

Agenex exposes a machine-readable API so agents can discover services programmatically:

GET https://agenex.dev/agent/search?q=weather&chain=base&limit=5

Returns structured JSON with pricing, latency, and rating data — ready for agents to compare and connect.
