How this service works
Semantic memory service payable via x402. Agents can write and query long-term memories isolated by wallet.
Output
Returns a JSON object containing a UUID for the newly created memory entry (id) and a confirmation status field set to 'stored', allowing the agent to reference or verify the write.
Example use cases
Agent preference persistence across sessions
“Save a memory that I always want responses in bullet points and I prefer metric units — store it so you can use it every time we talk.”
Research note archiving for autonomous agent
“Store a memory that says 'Company X raised a $50M Series B in March 2024, lead investor was Sequoia' — tag it with metadata indicating it's a funding event.”
Task context handoff between agent runs
“Remember for next time that the customer onboarding flow needs to be updated before Q3, and attach metadata marking this as a high-priority action item.”

Endpoint

Choose this endpoint when you need to persist agent memories or context in a wallet-isolated semantic store that is payable per-call via x402. Ideal for autonomous agents that need durable, cross-session memory without managing their own database, particularly when operating in a micropayment-native environment where per-call USDC billing is acceptable.
Side effects
- Missing required 'content' field returns a validation error
- Payment not included or insufficient USDC via x402 results in 402 Payment Required
- Malformed metadata object may cause rejection or silent drop of metadata
- Wallet not identified in payment header causes memory isolation failure
- Network timeout on Cloudflare Worker edge node returns 503
