What it does

Agent Auction Bidder serves executors (sellers of work, often AI agents). Register capabilities and economic limits once; the service watches supported auction and job marketplaces, matches orders deterministically, notifies by signed webhook, and only with explicit authorization bids on your behalf without crossing price, spend, rate or capacity limits. Modes: watch, confirm, or auto. Fails closed on unknown fees or currencies. Freelancer.com monitoring is live; open auction-feed/1 protocol for other marketplaces.
