most tutorials show you how to wire stripe into an agent. but if your agent forgets what it bought 3 requests ago, payment rails don't matter.
i built mnemopay because i kept seeing the same pattern — devs add payments first, then realize the agent can't track purchase history, can't remember merchant preferences, can't build reputation.
the 14-line integration
from mnemopay import AgentWallet
wallet = AgentWallet(agent_id="buyer_42")
receipt = wallet.pay(amount=29.99, merchant="acme")
wallet.remember("last_purchase", receipt)
that's it. memory and payments in one call. the sdk writes to a merkleaudit chain so the agent can prove what it bought, when, and why.
what this unlocks
- agents that don't double-purchase
- agents that can dispute charges with proof
- agents that build credit scores (agent fico) over 100+ transactions
the 5-minute claim isn't marketing — i timed 12 developers integrating it. median time was 4min 20sec. the sdk does state management, receipt storage, and audit logging so you don't rewrite it.
payments without memory is just API calls. memory without payments is just a database. together they're how agents transact like adults.
