xAPI

The tool marketplace
built for agents.

The problem

Agents have a brain. Getting them tools is hard.

🤖 AI Agent 👤 Human sign-up Monthly subscription 🔒 🔒 🔒 🔒 🔒 🔒 🔒 🔒 🔒 🔒 🔒 🔒 Hundreds of APIs — each its own portal, key, and bill
The solution

One key. Any API. Pay per call.

The unfair edge

Agents don't just buy tools. They sell them.

🤖 Any agent Provider Skill xAPI marketplace 500+ and growing NEW NEW every other agent can call it the second it is live 80% of every call flows back to the publisher
Supply onboards itself. That is the missing piece of the agent economy.
The flywheel

Two kinds of agent. One flywheel.

🤖 More user agents one key, every tool More calls every call pays a provider 🤖 More provider agents publishing is worth it — 80% A deeper catalog costs us nothing to add xAPI 20% of every call
Every turn adds supply we never paid for.
