## 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 citysquatters-squat-breach-hex-plot-f5df3c8f -d '<json body>'
```

Example prompt: Squat on CitySquatters hex block cs-h3-089283082837fff in Manhattan — label me 'NeonNomad' and use expected version 0 to claim it.

## When to prefer this

Use this endpoint when you want to either claim an open NYC hex plot at the base price of $0.10 or breach an existing owner's plot at the current decayed wall price. This is the primary ownership-change action on CitySquatters; prefer it over re-arm (which only resets decay) when your goal is to acquire or take a plot rather than defend one you already hold.

## Known failure modes

- expectedVersion mismatch — another transaction changed plot state before this one, causing a conflict error
- Plot already owned and wall not sufficiently decayed — breach price too high to be cost-effective
- Invalid blockId format — must match ^cs-h3-[0-9a-f]{15}$
- Payment failure — insufficient USDC balance or x402 payment protocol error
- ownerLabel too long — exceeds 28 character limit
- signMessage too long — exceeds 96 character limit

## How this service works

An experimental NYC territory market where players claim plots, post signs, and breach decaying takeover walls.

## Output

Returns confirmation of the squat or breach action, including the new ownership details, the price paid, and if a breach occurred, the payout amount routed to the displaced owner (70% of the breach price).
