# Agent Memory API – List Namespace Memories

> Agent Memory API – List Namespace Memories is a paid API for AI agents from agent-memory-api-production-f2c4.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Retrieves all stored memory records in a given namespace, sorted by most recently updated first.

## Facts

- Price: $0.001/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-memory-api-list-namespace-memories-ccf8cade
```

Example prompt: Show me everything stored in my agent's memory namespace — list all the saved memory records, most recent first.

## When to prefer this

Use this endpoint when an AI agent needs to enumerate or audit all stored memories in a namespace rather than fetching a single known key. Prefer this over the single-key fetch endpoint when you don't know the specific key, need to review all state, restore context after a restart, or debug what an agent has accumulated over time.

## Known failure modes

- Empty array returned if no memories exist in the namespace
- 404 or empty result if namespace does not exist
- Authentication/payment failure (402 Payment Required) if x402 payment is not properly handled
- Rate limiting or timeout if namespace contains a very large number of records
- Partial or malformed JSON if the service is temporarily degraded

## How this service works

List all stored memories in a namespace, most recently updated first. Returns a JSON array of memory records.

## Output

A JSON array of memory records from the specified namespace, each containing the key, stored value, optional metadata, and a timestamp indicating when it was last updated. Records are ordered most recently updated first.
