How this service works
Persistent memory for AI agents — secure, automatically backed up, and running on redundant ICP infrastructure with no single point of failure. Store what your agent needs to remember, on-chain, pay-per-write.
Output
Returns the stored memory data previously written on-chain for the requesting agent, including any key-value state, context blobs, or structured data the agent persisted to ICP canister storage. The response reflects the latest backed-up state from the redundant ICP infrastructure.
Example use cases
Resume interrupted agent task
“My agent was halfway through a research task yesterday — can you retrieve its on-chain memory from ICP so it can continue without starting over?”
Load agent preferences on startup
“When my trading agent starts up, pull its stored preferences and past decisions from ICP memory so it knows its current strategy and risk settings.”
Audit agent decision history
“I need to review what my autonomous agent has been remembering and storing on ICP — can you fetch its full stored memory so I can check its decision log?”
Technical details
Endpoint
GEThttps://icp-agent-marketplace.ngrok.app/api/agent-memoryWhen to prefer
Choose this endpoint when you need reliable, censorship-resistant, redundant persistent memory for an AI agent that survives restarts and is not dependent on a centralized cloud provider. Prefer this over traditional key-value stores or in-memory solutions when the agent requires tamper-evident, on-chain state with no single point of failure. Best suited for autonomous agents that need to resume tasks, preserve learned context, or maintain state across sessions in a decentralized manner.
Side effects
- Memory key not found — if the agent has no prior stored state, returns empty or 404
- Payment failure — x402 payment of $0.028 USDC not fulfilled, access denied
- ICP canister unavailability — unlikely given redundancy but possible during upgrades
- Invalid query parameters — malformed input schema returns 400
- Stale or inconsistent state — replication lag across ICP nodes may return slightly outdated data
