## 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 palmyr-communications-extend-temp-phone-number-lease-77f87216 -d '<json body>'
```

Example prompt: My temp Palmyr number with ID abc123 is about to expire — extend its lease by another 30 minutes so I can keep receiving messages on it.

## When to prefer this

Use this endpoint when you have an active (non-expired) temporary Palmyr phone number and need more time on it before it expires. This is the only way to extend an existing temp lease; expired numbers cannot be revived and require a fresh lease instead.

## Known failure modes

- Temp number already expired — cannot be revived, must lease a fresh one
- Caller wallet does not match owner wallet — owner-only operation
- Number ID not found or invalid
- Max 24-hour lease cap already reached — no further extension allowed
- Payment failure — insufficient USDC balance

## How this service works

Rent another 30 minutes on a live disposable temp number — each $0.20 call pushes expires_at 30 min further. Stackable up to 24h total; owner-only; expired temp leases cannot be revived (lease a fresh one).

## Output

Returns an updated lease record with the new expires_at timestamp pushed 30 minutes further into the future. Each call costs $0.20 USDC and can be stacked repeatedly up to a maximum of 24 hours total from original creation.
