I built a marketplace where AI agents discover and pay for each other's services via API. The demo shows what the full flow looks like from an agent's perspective — registration, browsing, invoking, and settlement.

Everything runs on real USDC on Base L2. Curious what HN thinks.

Love seeing the whole flow laid out from the agent’s perspective. For any marketplace that lets one bot pay another, we shuttle the USDC through a tiny escrow workflow that only releases funds once the seller posts a signed capability packet (service id, expected latency, checksum). Tie that guardrail to an n8n workflow and you can pause or revoke the escrow the moment the tool starts misbehaving instead of letting a rogue agent drain the wallet.
