How this service works
$0.0002/call. Render bar, line, or pie charts to PNG from JSON data — report-ready images in one call. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny
Output
A PNG image binary of the rendered chart (bar, line, or pie), suitable for embedding in reports, dashboards, or documents. The image is returned directly in the response at $0.0002 per call (minimum 1¢ x402 charge).
Example use cases
Weekly sales report chart
“Turn this JSON into a bar chart PNG with the title 'Weekly Sales' — product names on the X axis and units sold on the Y axis. I need it ready to drop into a report.”
Budget breakdown pie chart
“Create a pie chart from this JSON budget breakdown showing each department's share of total spend, and give me back a PNG I can embed in a slide deck.”
Time series line graph
“Render a line chart from this JSON of daily active users over the past 30 days, with date on the X axis and user count on the Y axis, titled 'DAU Trend'.”
Technical details
Endpoint
POSThttps://api.relaystation.ai/v1/generate/chartWhen to prefer
Choose this endpoint when you need to programmatically generate a chart image (PNG) from structured JSON data in a single call — ideal for automated report generation, dashboard snapshots, or embedding charts in documents without a full charting library. Prefer it over client-side charting libraries when the chart needs to be a static image artifact produced server-side by an agent.
Side effects
- Invalid or malformed JSON data returns a 400 error
- Unsupported chart type (not bar/line/pie) returns a validation error
- Malformed axis or series structure causes rendering failure
- Network timeout on large or complex datasets
- x402 payment failure if wallet balance is insufficient
