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 kiln-memory-list-namespace-documents-7f136606
```

Example prompt: List all the documents I have stored in my Kiln Memory namespace called 'user-sessions' — include any with the prefix 'session-2024'.

## When to prefer this

Use this endpoint when you need to enumerate or browse all documents stored in a known Kiln Memory namespace, optionally narrowing results by key prefix. Prefer it over single-document reads when you don't know the exact document key but want to discover what's stored. It is ideal for agent state audits, memory recovery after restarts, or inspecting shared memory partitions across an agent fleet.

## Known failure modes

- Namespace does not exist — returns empty list or 404-equivalent
- Invalid or missing 'ns' query parameter — request rejected with validation error
- Namespace has expired due to TTL — documents may be absent or namespace unavailable
- Prefix filter yields no matching documents — empty result set returned
- Authentication or payment failure — 402 Payment Required if USDC payment not provided

## How this service works

Durable JSON memory store for AI agents with TTL namespaces.

## Output

Returns a list of JSON documents stored within the specified namespace, potentially filtered by an optional key prefix. Each entry represents a durable memory record previously written by an AI agent, including its key and stored JSON content.
