Configuration

Parameter	Type	Default	Description
seed	str	—	12-, 18-, or 24-word TON wallet mnemonic
api_key	str	—	Tonapi key from tonconsole.com

Logging

pyfragment uses standard Python logging under the pyfragment namespace and is silent by default. To enable logs, configure your app's logging and set the level:

import logging

logging.basicConfig(level=logging.INFO)
logging.getLogger("pyfragment").setLevel(logging.DEBUG)  # DEBUG for detailed request logs

---

Credentials

Fragment cookies — log in to fragment.com and connect your TON wallet. You can get cookies in two ways:

• Automatically (recommended) — install the optional browser extra and use get_cookies_from_browser(), which reads them directly from your browser's on-disk store. No extension needed:

  pip install "pyfragment[browser]"
  

  from pyfragment import get_cookies_from_browser
  
  result = get_cookies_from_browser("chrome")  # or "firefox", "edge", "brave", ...
  # result.cookies — dict[str, str] to pass to FragmentClient
  # result.expires — ISO 8601 expiry of stel_ssid, or None for session cookies
  

• Manually — install Cookie Editor and export these four keys: stel_ssid, stel_dt, stel_token, stel_ton_token. Pass them as a dict or JSON string.

Refresh when you get authentication errors.

Tonapi key — generate at tonconsole.com.

Seed phrase — 24-word mnemonic from your TON wallet (Tonkeeper → Settings → Backup). Never share it.

Usage

import asyncio
from pyfragment import FragmentClient


async def main() -> None:
    async with FragmentClient(
        seed="word1 word2 ... word24",
        api_key="YOUR_TONAPI_KEY",
        cookies={
            "stel_ssid": "...",
            "stel_dt": "...",
            "stel_token": "...",
            "stel_ton_token": "...",
        },
    ) as client:
        wallet = await client.get_wallet()
        print(f"Wallet: {wallet.address} | TON: {wallet.ton_balance} | USDT: {wallet.usdt_balance}")

        recipient = "https://t.me/username"  # also supports: @username, username

        stars = await client.purchase_stars(recipient, amount=500, payment_method="usdt_ton")
        print(f"Stars sent: {stars.amount} to {stars.username} | tx: {stars.transaction_id}")

        premium = await client.purchase_premium(recipient, months=6, payment_method="ton")
        print(f"Premium sent: {premium.amount} months to {premium.username} | tx: {premium.transaction_id}")


asyncio.run(main())

Error Handling

All exceptions inherit from FragmentError. Catch specific ones or the base class:

from pyfragment import (
    ConfigurationError,   # invalid arguments (amount, months, payment_method, etc.)
    UserNotFoundError,    # recipient not found on Fragment
    WalletError,          # insufficient TON/USDT balance
    TransactionError,     # broadcast failed, duplicate seqno, invalid payload
    FragmentAPIError,     # Fragment API returned an error response
    FragmentPageError,    # page fetch or hash extraction failed
    AnonymousNumberError, # number not owned, wrong state, login code issues
    CookieError,          # missing or malformed session cookies
    ParseError,           # failed to decode Fragment payload
    VerificationError,    # on-chain verification step failed
    OperationError,       # generic operation-level failure
    UnexpectedError,      # unexpected API response structure
)
