Service overview
What is Chart Hero?
A Chart.js-compatible charting endpoint: POST a standard Chart.js config — the same `{ type, data, options }` you'd hand to `new Chart()` — and get back a rendered PNG. Backed by chartsplat.com, it renders every chart type chartsplat supports: bar, line, pie, doughnut, radar, polar area, and OHLC/candlestick (financial) charts, with the full set of Chart.js options (labels, multiple datasets, colors, titles, legends, scales). Made for embedding charts as images in agent reports, dashboards, Discord/Slack messages, and trading screenshots — anywhere you need a static image, not an interactive widget.
Level up your agent by giving it access to thousands of services. All payable per-request via x402. No API keys, no accounts.
Paste into your agentic chat and let your agent guide you.
