No key is required.\n\nThe chart is an interactive HTML page rendered by Vela 0.8.0 (Apache-2.0, LuxAlgo). Vela's own attribution mark stays on the chart, and the page also names Vela. PineTS is not used: the studies are Vela's native indicators, and the read uses the same standard formulas so the words match the lines.\n\nIt reports the last close, the change from the previous close, and the latest indicator values. It does not say whether to buy or sell, and it has no orders, broker, wallet or backtest.\n\nNothing about you is stored. The only lasting record is a daily count of calls. A hard cap of 800 calls a UTC day, and the per-network rate limit, keep the free data reads bounded.",
