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-create-namespace-38399633 -d '<json body>'
```

Example prompt: Create a new memory namespace in Kiln that lasts for 7 days (604800 seconds) so I can store my agent's session state there.

## When to prefer this

Choose this endpoint when an AI agent needs a fresh, isolated, TTL-bounded storage partition within the Kiln memory system before reading or writing documents. Ideal for multi-agent workflows, ephemeral task contexts, or session-scoped memory where data should auto-expire. Prefer over generic key-value stores when you need TTL-controlled namespacing with built-in agent-oriented JSON document support.

## Known failure modes

- ttlSeconds below minimum (3600) returns validation error
- ttlSeconds above maximum (2592000) returns validation error
- payment not included or insufficient returns 402 Payment Required
- malformed JSON body returns 400 Bad Request
- service unavailability returns 503

## How this service works

Create namespace

## Output

Returns a newly created namespace identifier along with its configuration metadata, including the TTL expiry time and namespace ID that agents can subsequently use to read and write JSON documents within that scoped memory partition.
