How this service works
Persistent memory for AI agents, paid per call via x402 (USDC, Base mainnet) — your wallet is your private, semantically-indexed memory namespace. Write $0.001, search $0.002, export $0.01; free trial + $2/30d unlimited subscription. MCP + HTTP. No account, no API key.
Output
Returns a JSON object with the subscription token (e.g. 'mem_...'), the associated wallet address, the subscription duration in days (30), and a Unix timestamp for when the subscription expires. This token can then be used to authenticate write, search, and export memory operations without per-call charges.
Example use cases
Activate flat-rate agent memory plan
“I want to subscribe to memory-mcp for 30 days so my agent can read and write memories without paying per call — go ahead and purchase the $2 subscription and return the token.”
Onboard a new agent with persistent memory
“Set up persistent memory for my new AI assistant by subscribing to the memory-mcp monthly plan — I'd rather pay once upfront than per operation.”
Renew lapsed memory subscription
“My memory-mcp subscription expired — can you re-subscribe for another 30 days and give me the new token and expiry date?”
Technical details
Endpoint
GEThttps://mem.borisinc.com/subscribeWhen to prefer
Choose this subscribe endpoint when an agent expects to perform many memory operations within a 30-day window and per-call costs ($0.001 write, $0.002 search) would exceed $2. Prefer this over per-call payment when running workflows that involve frequent memory reads/writes, or when operating continuously over days. If only occasional memory lookups are needed, per-call pricing may be cheaper.
Side effects
- Insufficient USDC balance in wallet — payment rejected, no token issued
- Invalid or missing wallet address — 400 or authentication error
- Duplicate subscription attempt while one is already active — may return existing token or error
- Network or blockchain congestion causing payment confirmation delay
- Expired or invalid x402 payment header — 402 response with payment requirements
