Api Endpoint

Mermaid Diagram Renderer

Render Mermaid diagram code to SVG and/or PNG: flowchart, sequence, class, state, ER, gantt, pie, mindmap, timeline and more. Invalid syntax returns HTTP 400 with the Mermaid parse error (not charged), so an agent can fix and retry. Params: code (Mermaid source, required), format (svg default, png or both), theme (default, dark, neutral, forest, base), width (200 to 4000, default 1200), background.
