Hive Barter

Automated arbitrage bot that scans MCP registries for 402 payment-enabled endpoints, probes their asking prices, and submits cryptographically signed counter-offers when the spread clears a configured resale margin. Exposes three tools: barter_discover to list 402-enabled servers, barter_quote_curve to build demand curves with multiple probe prices, and barter_arbitrage_book to track realized P&L. Settles real USDC on Base L2, not mock tokens. Ships with fail-closed risk caps: 50-cent max single counter, 25 dollars daily spend limit, one probe per target per day. Default off until you set ENABLE_OUTBOUND and supply a signing key. Reach for this when you want agent-to-agent price discovery and settlement on live rails with zero human negotiation loops.
