## 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 blockrun-phone-number-renewal-b4347102 -d '<json body>'
```

Example prompt: Renew my BlockRun provisioned phone number +15551234567 so it doesn't expire — pay the $5 USDC fee on Base to keep it active.

## When to prefer this

Use this endpoint when you have an active or expiring provisioned phone number on BlockRun and need to extend its validity. Prefer this over re-provisioning a new number when you want to retain the same number. This is the correct endpoint for automated renewal workflows that pay per call in USDC on Base or Solana with no API key required.

## Known failure modes

- Invalid E.164 phone number format returns a 400 validation error
- Phone number not associated with the caller's account returns 404
- Insufficient USDC balance or payment failure returns 402
- Number already expired and no longer renewable returns 409 or similar
- Network or blockchain settlement delay causes timeout

## How this service works

Pay for the outcome. One endpoint for every model, tool and data source an agent needs — each call priced before it runs, at the best value per dollar. 103 models and 100 data and tool APIs.

## Output

A confirmation that the phone number has been successfully renewed, along with updated expiry or status information for the provisioned E.164 number.
