Working agents, built in one prompt.
Reference builds from the prompt library. Every demo runs the agentic stack — UCP, A2A, AP2 — from a single Lovable build with the auto-provisioned LOVABLE_API_KEY.
Negotiation Theatre — two agents, one deal.
A buyer agent opens an AP2 IntentMandate, a seller counters via A2A, the loop collapses to a signed UCP order, and the buyer settles with a PaymentMandate. Both agents reason through Lovable AI Gateway.
Open the demo →Pay 0.01 USDC, unlock the endpoint.
HTTP 402 challenge → EIP-3009 authorization from a Privy embedded wallet → PayAI facilitator settles on Base Sepolia → server returns the payload with a PAYMENT-RESPONSE tx hash.
Open the demo →Vol. 01 · No. 03 · MPP · TempoPay a receipt, trigger the effect.
DanceTempo pattern: pay → receipt → side effect. MPP charge on Tempo Moderato (testnet, chainId 42431) verifies on-chain before the server unlocks a downloadable prompt pack.

Pick any entry from the index, paste its mega-prompt into Lovable — the auto-provisioned LOVABLE_API_KEY handles the agent reasoning — and your build joins the showcase.
