ChartsChart.jsData-visualizationImages

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.

Hand this page to an agent

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will check 0x04b5…d741's payment record before paying it over the free read API. No key, no account.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
