Chart Splat

A Chart.js-compatible charting API: POST a standard Chart.js `{ type, data, options }` — the same object you would hand to `new Chart()` — and get back a rendered PNG. Supports bar, line, pie, doughnut, radar, polar area, and candlestick/OHLC charts with the full set of Chart.js options. Pay per chart with x402 (USDC on Base) or use a Chart Splat API key — ideal for charts in agent reports, dashboards, and chat messages.
