mrxsim

Official Python client for MRXSIM.COM — purchase virtual numbers and retrieve SMS OTPs for every catalog service (Telegram, WhatsApp, Google, Instagram, PayPal, Snapchat, Other (SMS), and more).

Brand: MRXSIM · Domain: https://mrxsim.com · Package: mrxsim

Security first

• No hardcoded API keys in library source or examples.
• Prefer environment variable MRXSIM_API_KEY.
• Or load a local config.json that is gitignored.
• Never commit live keys. Revoke immediately if exposed.

Install

pip install mrxsim

From this repository (editable):

pip install -e .

Quick start (environment variable)

export MRXSIM_API_KEY="mrxs_your_key_here"   # Linux / macOS
# setx MRXSIM_API_KEY "mrxs_your_key_here"  # Windows (new shell)

from mrxsim import Client

with Client(country="england", service="telegram") as client:
    order = client.get_number()
    print(order["phone_number"], order["id"])

    sms = client.wait_for_sms(order["id"])
    print(sms["sms_code"])

One-shot purchase + OTP:

from mrxsim import Client

with Client(country="egypt", service="whatsapp") as client:
    result = client.buy_and_wait()
    print(result["phone_number"], result["sms_code"])

Quick start (config file)

cp config.example.json config.json
# edit config.json → set api_key, country, service

from mrxsim import Client

client = Client.from_config("config.json")
order = client.get_number()
sms = client.wait_for_sms(order["id"])
client.close()

MRXSIM_API_KEY overrides api_key in the file when set.

Get your API key

1. Open https://mrxsim.com and create an account.
2. Top up with Crypto (USDT / supported networks).
3. Profile → Get API KEY (shown once at create/regenerate).
4. Export MRXSIM_API_KEY or paste into gitignored config.json.

API surface

Header on every call:

X-API-Key: YOUR_KEY

Public order fields (zero-knowledge)

Successful responses expose retail fields only — aligned with the MRXSIM server OrderPublicOut contract:

Wholesale cost, upstream provider order IDs, markup multipliers, and internal flags are not part of the public API. The client also strips those keys client-side if they ever appear (defense in depth).

Changelog

1.0.1

• Document and enforce zero-knowledge public order fields.
• Sanitize responses to strip wholesale / upstream keys (cost_usdt, fivesim_order_id, markup fields, etc.).
• User-Agent bumped to mrxsim-python/1.0.1.

Examples

export MRXSIM_API_KEY="…"
python examples/buy_number_example.py
python examples/get_otp_example.py <order_id>
