Collection No. 01 — 3,000 Agentic Ideas

Agentic AI

Three thousand entries: one thousand originals wiring UCP checkouts, A2A negotiation and AP2 mandates — each paired with an x402 twin (Base Sepolia USDC) and an MPP twin (Tempo Moderato AlphaUSD) so every idea ships with a settlement rail an agent can call.

deterministic commerce01
UCP Checkout
a Zod-validated UCP merchant — `discovery` → `createCheckout` → `recordCheckoutPayment` — with RFC 9421 HTTP Message Signatures so any downstream agent or auditor can verify the order envelope without trusting the merchant
agent-to-agent loop02
A2A Negotiation
an A2A 0.3 `message/send` task between a buyer agent and a seller agent exchanging typed DataParts — IntentMandate (offer) → CartMandate + payment-required (counter) → PaymentMandate (accept) — both agents reason via Lovable AI Gateway
signed authority03
AP2 Mandates
AP2 Intent / Cart / Payment Mandates — EIP-712 typed envelopes the user signs once to grant an agent bounded spending authority (max ticket, daily cap, deadline), then the agent reuses across merchants
UCP + A2A + AP204
Full Agentic Loop
the full agentic-commerce stack: user signs an AP2 IntentMandate → buyer agent negotiates A2A with the seller → when price is fixed the loop collapses to a UCP createCheckout → seller returns an AP2 PaymentMandate the buyer can settle
agent-native micropayment05
Base x402
HTTP 402 + `PAYMENT-SIGNATURE` on Base Sepolia — the server issues a v2 challenge, the agent signs an EIP-3009 USDC authorization via a Privy embedded EVM wallet, the PayAI facilitator verifies and settles on-chain, and the server returns the protected payload with a `PAYMENT-RESPONSE` tx hash
verifiable AlphaUSD receipt06
Tempo MPP
pay → receipt → side effect on Tempo Moderato (chainId 42431) — the server 402s with a `WWW-Authenticate: MPP` challenge, the client pays AlphaUSD via TIP-20 `transfer` on `0x20c0…0001`, the server verifies the `Transfer` log against the payer and amount, and only then runs the unlock
