How this service works
Machine-payable document & media generation via x402 (USDC on Base). Endpoints respond 402 with payment instructions; retry with an x402 payment header.
Output
A standalone SVG (image/svg+xml) or PNG (image/png) image file containing the rendered diagram, returned after successful x402 USDC payment on Base.
Example use cases
Example prompt
“Generate a flowchart diagram showing a user login process with steps for entering credentials, checking authentication, handling failure with retry, and redirecting on success — output it as an SVG.”
Technical details
Endpoint
POSThttps://docforge-selim.duckdns.org/diagram?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically generate a diagram (flowchart, architecture, sequence, UML, etc.) as a standalone SVG or PNG image, are comfortable with the x402 micropayment flow on Base/USDC, and want a machine-payable API rather than a SaaS dashboard. Particularly useful in agentic workflows that need to embed or deliver diagrams without human-in-the-loop tooling.
Side effects
- 402 Payment Required — returned first to provide x402 payment instructions; caller must retry with a valid x402 payment header
- Invalid or insufficient payment — payment header malformed or USDC amount insufficient
- Unsupported diagram type or malformed input description — service may return 400 or error JSON
- Service unavailable on dynamic DNS host — duckdns.org domain may be offline or unreachable
- Timeout if diagram is complex or server is under load
