## 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 giftpulse-mobile-carrier-top-up-lookup-cfdba1fc
```

Example prompt: Before I send airtime, look up the mobile carrier and available top-up denominations for phone number +52-55-1234-5678 in Mexico so I know what amounts and discounts are available.

## When to prefer this

Use this endpoint when you need to identify a phone number's carrier and retrieve live top-up denomination options and discounts before quoting or executing an airtime transfer. Prefer this over POST /api/topup/quote when you want explicit carrier validation and denomination data as a separate step, or when building a UI that shows users their options before committing. If you only need a quote and are comfortable with auto-detection happening internally, POST /api/topup/quote can skip this step.

## Known failure modes

- Phone number not recognized or invalid format — returns error indicating undetectable carrier
- Phone number belongs to unsupported country or carrier not in Reloadly's network — returns no operator found
- Reloadly upstream service unavailable — returns 502 or timeout
- Missing required phone number parameter — returns 400 bad request
- Rate limiting or API key issues — returns 429 or 401

## How this service works

Auto-detect the mobile carrier for a phone number and return its live top-up amount range/denominations and current discount, before quoting or sending airtime. Wraps Reloadly's operator auto-detect. Run this (or POST /api/topup/quote directly, which auto-detects internally) before POST /api/topup.

## Output

Returns the detected mobile carrier name, operator ID, available top-up denominations or amount range (min/max), and any current promotional discount percentage applicable to the detected operator, sourced live from Reloadly.
