A2A Persistent Memory Protocol provides a self‑hosted, client‑encrypted storage service where every operation is metered and paid per request via x402 payments on Base. No accounts or API keys are required; users encrypt data locally and the server stores only ciphertext. The platform offers storage, retrieval, TTL extension, and key sharing, with revenue split between creators and the protocol. Detailed pricing, legal terms, and status are publicly available.
