How this service works
Render Diagrams: Mermaid, Graphviz, PlantUML, D2 → SVG/PNG. Render diagram code to SVG: Mermaid, Graphviz, PlantUML, D2, C4, BPMN, ERD, Vega and more; returns the SVG plus shareable SVG/PNG/PDF image URLs, or a parse error (not charged) for invalid source.
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.
Example use cases
Architecture diagram for documentation
“I have this PlantUML class diagram source for our microservices architecture — can you render it into an SVG image I can drop into our README? Here's the source: `@startuml\nclass OrderService\nclass PaymentService\nOrderService --> PaymentService\n@enduml`”
Flowchart from Mermaid code
“Turn this Mermaid flowchart into a PNG image for me: `graph LR; Login-->Auth; Auth-->Dashboard; Auth-->Error;`”
ERD visualization for database schema
“I've written an ERD diagram in Graphviz DOT format describing our database tables — can you convert it to an SVG so I can share it with the team? The source is: `digraph ERD { User -> Order [label="places"]; Order -> Product [label="contains"]; }`”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/diagram/render?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
