# SMSOTPS - Developer & LLM Integration Index

> SMSOTPS (smsotps.com) provides temporary phone numbers to receive SMS verification codes (OTP) online, across a wide range of services and countries, on site or via REST API.

SMSOTPS (`smsotps.com`) is a digital privacy platform that provides temporary, non-VoIP phone numbers for online SMS verification, so users can complete SMS verification screens without exposing their personal phone number.

## 1. Service Facts (verified against smsotps.com)

- **Number type**: Temporary numbers are connected to physical SIMs hosted by mobile networks (non-VoIP). Each service decides which number types it accepts, and its policy can change - no number type is promised acceptance by any service.
- **Single-use sessions**: A number assigned to an activation is reserved for the user's account and the chosen service while the session is active. Once verification completes or the session expires, the line is closed and cannot be accessed again.
- **Lease window**: A standard activation stays active for up to 20 minutes. Once the code is received or the window ends, the session closes.
- **Refund policy**: For standard one-time activations, if no SMS code arrives on the number, the full charge returns to the site balance. The user can cancel the order between 2 and 20 minutes after purchase, as long as no code has arrived, or it is refunded automatically when the number expires. Once a code arrives, the order is complete and non-refundable. Link-based bulk orders are not covered by automatic or self-service cancellation refunds.
- **Payments**: Cryptocurrency top-ups via Cryptomus - Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Tron (TRX) and USDT (Tether) - credited to the site balance after the payment confirms.
- **Pricing**: The price for the selected service and country is shown before payment. Homepage and pricing figures are a snapshot; live prices and stock load when a country is selected.

## 2. How the Activation Workflow Works

1. **Service & country selection**: The user picks the platform to verify (WhatsApp, Telegram, ChatGPT and more) and the country whose number that service expects.
2. **Price check, then purchase**: The price for the service and country is shown before paying. The user tops up the balance with cryptocurrency and confirms the activation.
3. **Number lease**: The system leases a temporary number and presents it on the user's dashboard, active for up to 20 minutes.
4. **Code delivery**: The user pastes the number into the app's registration form and requests the code once. The incoming SMS code appears on the user's dashboard next to the number.
5. **Session completion**: If the code is received, the balance charge is final. If no code arrives, the charge returns to the balance automatically when the number expires, or the user can cancel between 2 and 20 minutes after purchase.

## 3. Developer REST API

SMSOTPS offers a REST API for developers to integrate verification workflows: list services and countries, check live prices and availability, order numbers, poll activation status, and cancel sessions programmatically.

- **Authentication**: API key sent as the `X-API-KEY` header or `?api_key=` query parameter. Keys are generated from Profile Settings, can be rotated and revoked, and must be stored server-side only.
- **Documentation**: Full endpoint reference, code examples, rate limits and error codes at https://smsotps.com/apidocs
- **Brand GitHub** (docs only): https://github.com/smsotps
