## 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 disposable-phone-number-for-sms-verification-ac029e74 -d '<json body>'
```

Example prompt: Get me a disposable phone number I can use to verify a Telegram account — something cheap, preferably in the US or UK — and then poll for the SMS code once it arrives.

## When to prefer this

Use this endpoint when an AI agent needs to automate SMS-based verification or account registration for a known service (Telegram, WhatsApp, Google, OpenAI, etc.) without exposing a real phone number. Ideal for single-use verification flows where a persistent number is not required. Settle-on-delivery pricing means no risk of paying for an unavailable number. Prefer this over managing your own virtual number infrastructure or scraping free number services.

## Known failure modes

- No number available for the requested service/country/operator combination — no charge applied
- Service name not recognized or unsupported — returns an error
- Requested country or operator not available at this time
- Payment not settled before timeout — number released
- Network or provisioning failure at the upstream wholesale provider

## How this service works

Buy a disposable phone number for one-time SMS verification, resold wholesale for AI agents. Give a service (e.g. 'telegram', 'whatsapp', 'google', 'discord', 'openai') and optionally a country/operator; you get a reachable number plus a handle. Poll the free POST /agent/phone-code with that handle for the incoming code (usually within a minute). Settle-on-delivery: no number available means no charge. Disposable use only — no guarantee a given platform accepts it.

## Output

Returns a provisioned disposable phone number and a polling handle. The agent then calls POST /agent/phone-code with the handle to retrieve the incoming SMS verification code. Charge is only applied if a valid number is delivered (settle-on-delivery). Price is dynamic and disclosed in the 402 response before payment, starting from ~$0.30 USDC, varying by country and operator.
