If a billable call times out, check `get_usage_history` before retrying\n2. Generation is synchronous and can run for minutes. The SDKs default to a 450 s timeout, or use `POST /diagrams/stream`\n3. Call `list_capabilities` first. `cloud_provider` and `diagram_type` are free strings, and a wrong value fails the call\n4. `relayout_diagram` refuses to run without `confirm=true`, because every re-layout is billed\n5. Test keys (dgz_test_) spend the same credits as live keys\n\n## Other comparisons with Cloudviz API or Diagrams.so API + MCP\n\n- [Cloudviz API vs draw.io + MCP](https://www.anchorterminal.com/compare/cloudviz-vs-drawio.md)\n- [Cloudviz API vs Eraser API + MCP](https://www.anchorterminal.com/compare/cloudviz-vs-eraser.md)\n- [Cloudviz API vs Lucid API + MCP](https://www.anchorterminal.com/compare/cloudviz-vs-lucid.md)\n- [Cloudviz API vs Mermaid Chart MCP](https://www.anchorterminal.com/compare/cloudviz-vs-mermaid-chart.md)\n- [Cloudviz API vs Structurizr + MCP](https://www.anchorterminal.com/compare/cloudviz-vs-structurizr.md)\n- [Cloudviz API vs tldraw SDK + MCP](https://www.anchorterminal.com/compare/cloudviz-vs-tldraw.md)\n- [Cloudviz API vs Whimsical MCP](https://www.anchorterminal.com/compare/cloudviz-vs-whimsical.md)\n- [Diagrams.so API + MCP vs draw.io + MCP](https://www.anchorterminal.com/compare/diagrams-so-vs-drawio.md)\n- [Diagrams.so API + MCP vs Eraser API + MCP](https://www.anchorterminal.com/compare/diagrams-so-vs-eraser.md)\n- [Diagrams.so API + MCP vs Lucid API + MCP](https://www.anchorterminal.com/compare/diagrams-so-vs-lucid.md)\n- [Diagrams.so API + MCP vs Mermaid Chart MCP](https://www.anchorterminal.com/compare/diagrams-so-vs-mermaid-chart.md)\n- [Diagrams.so API + MCP vs Structurizr + MCP](https://www.anchorterminal.com/compare/diagrams-so-vs-structurizr.md)\n- [Diagrams.so API + MCP vs tldraw SDK + MCP](https://www.anchorterminal.com/compare/diagrams-so-vs-tldraw.md)\n- [Diagrams.so API + MCP vs Whimsical MCP](https://www.anchorterminal.com/compare/diagrams-so-vs-whimsical.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-04", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "Cloudviz API vs Diagrams.so API + MCP", "url": "" } ], "description": "Diagrams.so API + MCP has a score of 60.1 (C) against Cloudviz API's 37.9 (F).
