Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 saylor-innovations-diagram-renderer-27638893
```

Example prompt: Can you render this Mermaid flowchart source code into an SVG for me? Here's the diagram text: `graph TD; A-->B; A-->C; B-->D; C-->D;`

## When to prefer this

Choose this endpoint when you need to programmatically convert textual diagram source code (Mermaid, Graphviz DOT, PlantUML, D2, C4PlantUML, BPMN, ERD, nomnoml) into a visual SVG or PNG image, especially in agentic or automated pipelines where paying per-call via x402 micropayments is acceptable. Prefer it when you need multi-format diagram support in a single API rather than integrating separate rendering libraries.

## Known failure modes

- Invalid or malformed diagram source syntax returns rendered: false with no image output
- Unsupported diagram type string causes a parameter error
- Missing required 'source' query parameter results in a bad request response
- Very large or complex diagrams may time out or return an error
- Network or upstream rendering engine errors may cause intermittent failures

## How this service works

Render Diagrams: Mermaid, Graphviz, PlantUML, D2 → SVG/PNG — Developer Tools

## Output

Returns a JSON object indicating whether rendering succeeded (rendered: true/false), the SVG markup as a string if applicable, and image_urls containing links to the generated image formats (e.g. PNG). On success the SVG string can be embedded directly into HTML or documentation.
