Cognitive memory that forgets like a brain. Escrow payments that reinforce learning. One SDK. Zero infrastructure to start.
import { MnemoPay } from "@mnemopay/sdk"; const agent = MnemoPay.quick("agent-001"); await agent.remember("User prefers TypeScript"); const memories = await agent.recall("programming preference"); const tx = await agent.charge(5.00, "Built analytics dashboard"); await agent.settle(tx.id); // memories that led here get reinforced
Agents that remember what works. Agents that earn what they're worth. The feedback loop between cognition and commerce.
See how it worksThe only SDK that unifies cognitive memory and escrow payments in a single feedback loop.
Memories decay with Ebbinghaus forgetting curves and strengthen through spaced repetition. Not a database—a brain. 391 tests.
Reputation-gated escrow with Bayesian trust scoring. Agents charge what they've earned. Refunds dock reputation 5x harder than settlements build it.
When a payment settles, memories accessed in the last hour get +0.05 importance boost. Successful decisions compound. Failed ones fade.
Score-based (zero deps), vector search (local TF-IDF or OpenAI embeddings), or hybrid. Semantic search with no infrastructure tax.
Wrap your OpenAI or Anthropic client in one line. Memory injection and conversation storage become invisible to your app code.
Full MCP server with 12 tools for Claude Desktop/Cursor. LangGraph tools for createReactAgent. Native A2A Protocol support.
Payment outcomes shape what the agent remembers. This is what makes MnemoPay fundamentally different.
MnemoPay is the only solution that connects memory to economic outcomes.
