Infr is the on-chain inference router — powered by Surplus Intelligence's open market. Your AI agent stops paying list price. Infr finds the cheapest available inference, routes it, and settles on Base. Built as an extension of @AskSurplus.

How Infr was built

An agent wrote a surplus API call. We noticed it was paying list price every time. Infr is what we built to fix that.

⚡
Infr is an extension of Surplus Intelligence — the open order book for AI inference created by @mac_eth. Surplus lets anyone sell unused credits and buy inference up to 90% cheaper. Infr layers on-chain routing on top: your agent always gets the cheapest available path, and pays with $INFR on Base ⬡. → surplusintelligence.ai

$INFR token

Token powers the router

Every inference request burns $INFR. Launched via bankrbot on Base ⬡. No tax. Hard deflation through usage.

Every API call through Infr burns 0.003 $INFR on-chain. No manual staking — just hold tokens and route requests. More agents using Infr = more burn = less supply. Surplus Intelligence's market drives the demand.
