How this service works
Agent memory: save, get, search, list and delete notes that persist between sessions, private to the wallet that pays. Up to 2,000 keys per wallet, 16,000 characters per value. Pay with an EVM wallet. Also callable as GET with the same fields as query parameters.
Output
Returns the stored value for a get action, a list of matching keys/values for list or search actions (up to the specified limit), or a confirmation message for save and delete actions. All data is scoped privately to the wallet that paid for the call.
Example use cases
Persist user preferences across sessions
“Save a memory note with key 'user-prefs' and value 'prefers metric units, vegetarian diet, lives in Berlin' so you remember this about me next time we talk.”
Retrieve a saved agent context
“Look up the note I saved under the key 'client-meeting-notes' and read it back to me.”
Search stored notes by topic
“Search my saved agent memories for anything related to 'budget' and list what you find, up to 10 results.”

Endpoint
GEThttps://agentrxi.com/v1/memory?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs durable, cross-session memory scoped to a specific wallet identity — for example, storing user preferences, tracking intermediate task state, or persisting facts between separate LLM conversations. It is ideal when you want memory that is private to a paying wallet (not shared), supports up to 2,000 distinct keys, and requires simple key-value semantics with full-text search. Prefer alternatives if you need relational queries, large binary storage, or shared/collaborative memory.
Side effects
- Key not found: returns empty or error if the specified key doesn't exist
- Wallet limit exceeded: error if the wallet already has 2,000 keys stored
- Value too long: error if value exceeds 16,000 characters
- Missing required 'action' parameter: request fails without specifying save/get/search/list/delete
- Payment failure: call not executed if USDC payment via x402 is not completed
- Invalid action value: returns error if action is not one of the five accepted enum values
