POST /v1/mermaid

unprobed

Render a Mermaid diagram (flowchart, sequence, class, state, ER, gantt, pie, mindmap, timeline, ...) to PNG, SVG or PDF. Headless Chrome, offline. Invalid syntax returns the Mermaid parser error and you are NOT charged.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
