## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-dataviz-chart-renderer-c40bc23f
```

Example prompt: Render a bar chart as SVG showing monthly sales — January: 1200, February: 950, March: 1400, April: 1100 — with labeled axes and a title 'Monthly Sales Q1.'

## When to prefer this

Choose this endpoint when you need a lightweight, server-side SVG chart rendered from raw data without setting up a charting library client-side. Ideal for agents generating reports, dashboards, or embedded visuals where SVG output is preferred. Good for bar, line, or area chart types when a low-cost ($0.01 USDC) per-call pay-as-you-go model is acceptable.

## Known failure modes

- Missing or malformed data payload returns an error
- Unsupported chart type requested returns a validation error
- Payment not included or insufficient (x402 payment required at $0.01 USDC)
- Empty dataset results in a blank or error response
- Malformed JSON body causes a 400-level error

## How this service works

Render a bar/line/area chart to SVG

## Output

An SVG document containing the rendered chart — a scalable vector graphic that can be embedded in web pages, reports, or documents, representing the input data as a bar, line, or area chart with axes and labels.
