## 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 zerohost-evmoore-workers-dev-zerohost-extend-deploy-ttl-5dc129d8 -d '<json body>'
```

Example prompt: My Zerohost deploy abc123 is about to expire — extend it by 6 more hours.

## When to prefer this

Use this endpoint when you have an existing Zerohost disposable backend that is still running (or recently created) and you want to keep it alive beyond its original TTL. It is cheaper than creating a new deploy when you just need more time on an already-configured backend, since there is no base fee — only per-hour charges. Prefer this over re-deploying when state or the existing URL must be preserved.

## Known failure modes

- Deploy ID not found — returns 404 if the specified deploy does not exist or has already expired
- Insufficient payment — returns payment error if USDC balance is insufficient for the requested TTL hours
- Invalid TTL value — returns 400 if X-Zerohost-Ttl-Hours header is missing, zero, or non-numeric
- Deploy already expired — may return 404 or 410 if the deploy TTL has already lapsed
- Authentication failure — returns 401 if the caller is not the owner of the deploy

## How this service works

Extend an existing deploy by X-Zerohost-Ttl-Hours. Charged at per-hour × ttlHours (no base fee).

## Output

Returns a JSON object confirming the extended deploy, including the new expiry timestamp and the updated TTL details. The call is charged at the per-hour rate multiplied by the number of TTL hours requested, with no base fee.
