How this service works

Read from a wallet-scoped namespace.

Output

If a key is provided, returns the stored value associated with that key in the wallet-scoped namespace. If no key is provided, returns a list of all stored keys in the namespace. If an owner address is provided, reads from that granted namespace instead.

Example use cases

Example prompt

“Retrieve the value stored under the key 'user_preferences' from my wallet namespace — or if I don't specify a key, just list all the keys I've stored.”

Technical details

Endpoint

GEThttps://agent402.tools/api/memory?utm_source=zero.xyz

When to prefer

Use this endpoint when an agent needs to retrieve previously stored state or configuration from its wallet-scoped persistent memory. Prefer this over generic KV stores when the storage is already tied to the agent402 ecosystem and you need wallet-scoped access control with grant-based sharing between wallets.

Side effects

Key not found — returns empty or 404-style response if the key does not exist in the namespace
Unauthorized access — attempting to read a namespace without a valid grant returns a permission error
Invalid owner address — malformed 0x address returns a validation error
Payment failure — insufficient USDC balance or x402 payment not processed results in a 402 error
Empty namespace — listing keys on a namespace with nothing stored returns an empty list

Reviews

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
