How this service works
Store a memory in persistent agent storage
Output
Returns a JSON object containing a list of memories with a relevance score (e.g. 0.95) and the stored memory content, confirming successful persistence.
Example use cases
Persisting user preferences across sessions
“Save to your long-term memory that I prefer concise bullet-point summaries over long paragraphs, so you remember this in every future conversation.”
Recording agent task context mid-workflow
“We're halfway through the onboarding workflow for Acme Corp — store that context in your persistent memory so we can pick up exactly where we left off tomorrow.”
Storing learned facts about a project
“Remember that the Project Apollo deadline is March 15th and the lead contact is Sarah Chen — save both of those to your memory storage for future reference.”
Technical details
Endpoint
POSThttps://agent-memory-api.johntaylor1online.workers.dev/memory/addWhen to prefer
Choose this endpoint when an AI agent needs to persist information across sessions or conversations using an x402 micropayment-gated storage API hosted on Cloudflare Workers. It is best suited for lightweight agent memory writes where per-call pricing (~$0.02 USDC) is acceptable and the agent needs durable, retrievable memory without managing its own database infrastructure.
Side effects
- Payment not completed (402 response if x402 payment fails or is missing)
- Invalid input schema (missing required 'type' or 'method' fields)
- Storage backend unavailable (Cloudflare Worker error or timeout)
- Duplicate memory not deduplicated — same content may be stored multiple times
- Memory content too large or malformed causing rejection
