How this service works

86 APIs for AI agents: web scraping and crawling to Markdown, AI summaries, data extraction and cited answers, screenshots and PDF, PDF, OCR and document conversion, news, paper and developer search and more, paid per call with USDC on Base, Solana, Polygon or Arbitrum via x402. No account, no API key, free sample on every service.

Output

A JSON object containing the rendered chart as a base64-encoded PNG string, along with the width and height in pixels, file size in bytes, mime type (image/png), and the chart type that was rendered. The agent can decode the base64 string to embed or save the image.

Example use cases

Sales dashboard chart for email report

“Generate a line chart titled 'Q1 Sales Trend' with weeks Week 1 through Week 13 on the x-axis and two datasets — 'Product A' with values [500,520,480,610,590,640,700,680,720,750,800,780,830] and 'Product B' with values [300,310,290,340,360,380,400,390,420,410,450,440,460] — at 900 by 500 pixels, and return the PNG image.”

Survey results as pie chart

“Create a pie chart called 'Customer Satisfaction Survey' with labels ['Very Satisfied','Satisfied','Neutral','Dissatisfied','Very Dissatisfied'] and data values [45, 30, 12, 8, 5], 800 by 600 pixels, white background — I need the base64 PNG to paste into our presentation.”

Feature comparison radar chart

“Render a radar chart titled 'Product Comparison' comparing three products across the axes ['Price','Performance','Support','Ease of Use','Reliability'] with scores Product A [4,5,3,5,4], Product B [3,4,5,4,3], Product C [5,3,4,3,5], at 700 by 700 pixels.”

When to prefer

Choose this endpoint when you need a server-side rendered chart image (PNG) from structured data or a Chart.js config, without requiring a browser, frontend framework, or chart library on the client. It is ideal for agents generating reports, emails, or documents that need embedded chart images. It supports all major Chart.js chart types and accepts both simplified label/dataset inputs and full Chart.js config objects.

Side effects

Invalid chart type enum value returns validation error
Malformed or missing datasets causes rendering failure
Width or height outside 100–2000 range is rejected
Conflicting chart type between top-level 'type' and 'config.type' may produce unexpected output
Very large datasets or complex configs may timeout
Missing required data arrays produce an empty or broken chart image
