  title: A2A Persistent Memory Protocol Auth API
  version: 0.1.0
  description: Encrypted, pay-per-use persistent memory storage for AI agents (and humans), gated by the x402 HTTP-402 payment standard on Base L2. This document describes the REST surface; the same operations are also available over MCP (streamable HTTP) at /mcp -- see /.well-known/agent-memory.json for pricing, TTL limits, and links. Endpoints marked 402 respond with an x402 payment-required challenge (see https://github.com/x402-foundation/x402) when no valid on-chain payment authorization is attached to the request; a wallet-funded credit balance or the free per-wallet trial allowance can also satisfy these instead of a fresh payment.
