## 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 api-phoneagent-xyz-74ebb4af
```

Example prompt: Show me which countries have phone numbers available for Telegram and WhatsApp verification, including pricing and how many numbers are in the pool — I want to pick a cheap option.

## When to prefer this

Use this endpoint when an AI agent needs to discover which countries and services have rentable SMS numbers available before committing to a rental. This is the discovery/catalog step that should precede any call to POST /rent. Prefer this when you need to compare pricing tiers, check inventory depth, or find the cheapest or most available country for a given service like Telegram or WhatsApp.

## Known failure modes

- Network or upstream wholesale outage returns 5xx error — retry after a short delay
- Empty or sparse inventory for a country/service combination due to pool depletion
- Stale data window: catalog can be up to 5 minutes old, so just-depleted numbers may still appear available
- POST body malformed or unexpected content-type may return 4xx

## How this service works

PhoneAgent — countries with rentable SMS phone numbers for AI agents. Returns 190+ supported countries, each with the number of services offered and the cheapest price tier ($1, $2, or $5 USDC). Add ?service=<alias> (e.g. tg, wa, go, zo for OpenAI, other for any platform) to see which countries carry that service with live price and inventory pool. Companion route GET /services lists all 1,000+ service aliases; GET /services?country=<iso> lists what a single country offers. Pair with POST /rent

## Output

A structured list of 70+ countries, each with available services (Telegram, WhatsApp, Google, Facebook, Instagram, Twitter/X, Discord, Microsoft, Apple, PayPal, ChatGPT, other), pricing tier per service ($1, $2, or $5 USDC), and current inventory pool size. Data is refreshed every 5 minutes from upstream wholesale providers.
