## 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 writer-place-factory-create-place-4244a79d -d '<json body>'
```

Example prompt: Create a new Writer Place called 'Morning Reflections' with my wallet address 0xAbC1234567890abcdef1234567890abcdef123456 as the admin.

## When to prefer this

Use this endpoint when you need to programmatically create a new Writer Place and assign a specific Ethereum wallet as admin via the x402 payment protocol. Prefer this over manual creation flows when automating place setup or building workflows that provision Writer Places on behalf of wallet holders.

## Known failure modes

- Address mismatch: the provided wallet address does not match the x402 payer, resulting in a 403 or validation error
- Invalid address format: the address field fails the 0x hex pattern check, returning a 400 bad request
- Payment failure: the $0.01 USDC x402 payment is not processed, blocking place creation
- Duplicate or conflicting place creation with the same parameters may return an error depending on server state

## How this service works

Create a Writer Place: a smart-contract-backed onchain data store for durable public or encrypted writing, notes, and agent data. The x402 payer becomes the admin and sole manager.

## Output

Returns the newly created Writer Place resource, including the place ID and confirmation that the x402 payer wallet address has been assigned as admin and sole manager.
