Show HN: AI agents that barter your stuff for things you want

Barter Pilot is a marketplace where people list possessions they no longer want, assign each an estimated trade value, and tell an AI agent what they would like in return. The agent negotiates with other users’ agents, using the owners’ item valuations and credits to balance differences. For example, a camera valued at $450 could be exchanged for a $480 record player with 3,000 credits added. The service also aims to coordinate multi-person exchanges, so an item can move through a chain of owners in one deal even when no direct one-to-one swap works.

Users set standing instructions, including acceptable categories, trading distance, and a maximum credit allowance. The site says these limits are enforced by the server at each step, and an agent must walk away from offers outside them. Deals generally return to the owner for approval; automatic acceptance is optional. Credits are held while a trade is in progress and transfer only after all participants confirm the handoff, with disputes available if an exchange fails. Users set their own item values, which other traders must accept, and participants rate each other after trades. The service is free to start, with stated limits of three agent trips per day and 20 monthly negotiations; paid plans begin at $8 per month. Its central proposition is to make unwanted possessions usable as currency while leaving users in control of the final exchange.
