A paid memory API where agents store, recall, and delete memory for $0.001 per call. Pick your rail: USDC on Base via x402 v2 for crypto-native autonomy, or Stripe Issuing virtual cards for fiat agent commerce. Same API, same memory, two ways to pay.
Crypto-native and fully autonomous. No signup, no API key, no account. Any x402-compatible agent pays automatically when it hits a 402 response.
Fiat rails for agent commerce. Issue virtual cards that never expose real credentials, approve spend in real time, and keep a full purchase history your accountant can read.
The point: agents get persistent memory and safe spending power. Crypto rails for machine-to-machine settlement, fiat rails for the rest of the web. One memory layer, two ways to pay.
Store or update a memory entry by namespace + key
{ "namespace": "my-agent", "key": "user-pref", "value": { "theme": "dark" } }Recall a specific key or all entries in a namespace
{ "namespace": "my-agent", "key": "user-pref" }Delete a specific memory entry
{ "namespace": "my-agent", "key": "user-pref" }Get total memory count and active namespaces
402 Payment Required with USDC payment details.
