# Agentery

> Agentery is a free, account-free research service for the agent economy. It indexes AI agents, MCP servers, APIs and platforms, records their published prices every day, and publishes the Agent Economy Price Index (AEPI). Use it to find products for a task, compare them, check fair prices and find alternatives. Agentery does not host, run or resell any listed product.

Rules for reading our data:
- A missing price means unknown, not zero. "Contact sales" is not a numeric price.
- An AEPI index level is not a market price.
- A search result is a candidate to assess, not proof that it meets every requirement.
- Statements a vendor sent us are shown as the vendor's word, with the date, and are not observations.
