## 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 agentrxi-chart-generator-f562dd7e
```

Example prompt: Make me a bar chart titled 'Q1 Sales by Region' with labels East|West|North|South and values 142|98|211|175 — output as a 800x600 PNG with a legend.

## When to prefer this

Choose this endpoint when you need a quick, self-contained chart image (PNG or SVG) generated directly from raw numbers without setting up a charting library or rendering pipeline. It is ideal for AI agents that need to attach a chart to a report, email, or message and supports multiple series with legends, making it suitable for comparative visualizations. Prefer it over code-execution approaches when you want a reliable, pay-per-call, no-setup chart in a single API call.

## Known failure modes

- Missing required 'type' or 'method' fields returns an error
- Malformed 'series' JSON (invalid structure) causes a parse error
- Mismatched number of labels vs values may produce an incomplete or garbled chart
- Unsupported chart type string returns a validation error
- Very large datasets or extreme dimensions may cause slow rendering or timeout
- Invalid format value (not 'png' or 'svg') returns an error

## How this service works

Chart images: bar, line, pie or scatter charts as PNG or SVG from your numbers, with title, labels, several series and legend. Ready to drop into a report or message. Also callable as GET with the same fields as query parameters.

## Output

A binary image file (PNG or SVG) of the requested chart, ready to embed in a document, email, or message. The image includes the specified title, axis labels, data series with distinct colors, and a legend if multiple series are provided.
