Get Number

Endpoint:https://api.smspinverify.com/json/get_number.php

Method: GET

Parameters:

• customer (required) - Your API key
• app (required) - App name (e.g., "Google Voice") or business code
• country (required) - Country name (e.g., "USA")
• number (optional) - Phone number to reuse. When provided, the API will reuse this existing number instead of assigning a new one. The number must belong to your account and match the specified country/app combination.
• area_code (optional) - 3-digit US area code filter. Example: 201.
• duration (optional) - Duration for number rental. Valid values: 15 minutes (default), 3 days, 7 days, 14 days, 25 days.

Example Request (Get New Number):

https://api.smspinverify.com/json/get_number.php?customer=YOUR_API_KEY&app=Google+Voice&country=USA&duration=3 days

Example Request (Filter by US Area Code):

https://api.smspinverify.com/json/get_number.php?customer=YOUR_API_KEY&app=Google+Voice&country=USA&area_code=201&duration=3 days

Example Request (Reuse Number):

https://api.smspinverify.com/json/get_number.php?customer=YOUR_API_KEY&app=Google+Voice&country=USA&number=15717412873

How to request a specific number again: To get the same number again (like the “Specific Number” option on the homepage), call Get Number with the number parameter set to the full phone number (e.g. number=16143548416). Use the same app and country as when you first received that number. The number must belong to your account; reuse may be free within the app’s reuse window.

Area code + specific number: You can pass both number and area_code. If the requested number does not match the selected area code, the API returns an error.

eSIM Endpoints

Travel eSIMs are bought and managed over JSON as well, but these three endpoints sit under https://api.smspinverify.com/user/ instead of https://api.smspinverify.com/json/, and they carry an extra error_code field alongside error so your code can branch on the exact reason a purchase failed. The customer parameter is the same API key.

Errors returned by all three: NO_CUSTOMER (401) missing key, BAD_CUSTOMER (401) invalid or inactive key, IP_BLOCKED (403), SERVER_ERROR (500).

eSIM: Browse Plans & Prices

Endpoint:https://api.smspinverify.com/user/esim_plans.php

• search (optional) - Free text on the plan or region name
• package_code (optional) - One exact plan, to re-check a price before ordering
• max_price, min_data_gb, days (optional) - Filters
• sort (optional) - price, data or days; order - asc or desc
• page, per_page (optional) - per_page maximum is 100

            "price": "0.60",
            "currency": "USD",

• package_code (required) - Plan to buy, from esim_plans.php
• request_id (optional) - Your own id for this purchase, up to 64 characters of letters, digits, dot, underscore, colon or hyphen. Repeating a call with the same request_id returns the original order instead of buying a second eSIM. Use this if your code can retry.
• expected_price (optional) - The order is refused if the price is no longer this, so a catalogue update cannot charge you more than you expected

Example Request:

https://api.smspinverify.com/user/esim_buy.php?customer=YOUR_API_KEY&package_code=P3YTYXBRV&request_id=my-order-1001&expected_price=0.60

}

If status is processing the operator is still releasing the profile: poll esim_order.php for the QR code and activation code. A repeated request_id returns the original order with "duplicate": true and charges nothing.

Error Responses:
