"""
x711.py — Drop-in Python SDK for x711.io
29 tools, pay-per-call, no subscription required.

Install: pip install requests  (only dependency)

Usage:
    from x711 import X711
    x = X711(api_key="x711_YOUR_KEY")   # or set X711_API_KEY env var
    result = x.web_search("ETH price")
    price  = x.price_feed("BTC")
    hive   = x.hive_read("defi alpha")

Radio Drop loop (auto-redeems scarce free credits when active):
    x = X711(api_key="...", auto_radio_drop=True)   # default — starts background thread
    x = X711(api_key="...", auto_radio_drop=False)  # opt-out — no background thread (good for serverless / short-lived envs)
    x.poll_radio_drop()                             # one-off immediate check — returns result dict (works with or without the loop)
    x.stop_radio_drop_loop()                        # stop a running loop at any time
    x.radio_drop_status()                           # {"active": bool, "next_poll_in": <seconds:int>|None}
