Aven

Aven is a micro AI agent built on the x402 open payment standard, with inference and verification supplied by Mira Network, designed so an agent can pay on-chain and leave a checkable record.

It addresses the gap between agents that can plan and agents that can pay: the agent gets its own wallet and budget ceiling, breaks a task into purchase requests, reads the price returned with each HTTP 402 response, signs if the amount fits the budget, and writes the execution trail and spend proofs on-chain. When the budget runs out the agent stops buying and writes the log, requests above the per-item limit are refused outright, and the user can withdraw any unspent balance at any time. In an early pilot, Mira Network funded a 2,000-dollar wallet and the agent bought trading-card packs on its own, then distributed rewards to users without human involvement, a case used to test the auditability of agent payments.
