For every storm currently active you get the latest observed position (latitude, longitude, central pressure, max wind speed, Beaufort force, movement direction and speed, 7-level wind radii) plus the official forecast track at 12/24/36/48/60/72/96/120 hours with predicted intensity. Query a specific storm with ?id=, full history with ?track=1, or ended storms too with ?all=1. 中文：台风实时路径与官方预报（含实测点、强度等级、移向移速、七级风圈半径和逐 12~120 小时预报点）。 No API key and no signup: call the endpoint, it answers HTTP 402 with the payment terms, pay per request in USDC on Base with any x402-compatible client or wallet, then retry the same request to get the data.
