# PatentFig AI
> PatentFig AI is an AI patent drawing platform: a web workspace for creating patent-compliant technical drawings, line art, multi-view renderings, and flowcharts, plus a public REST API for figure generation and conversion.

## Public API
- [API documentation](https://patentfig.ai/docs): Quickstart, authentication, endpoint reference, and error codes.

- [Agent Skill](https://github.com/TopLocalAI/patentfig-skill): Open-source SKILL.md that teaches AI agents (Claude Code and compatible) to call this API directly.
- Endpoints: POST /api/v1/figures (generate patent figures from a prompt, PNG or SVG), POST /api/v1/vectorize (raster to SVG/DXF/vector PDF), POST /api/v1/enhance (AI upscaling), POST /api/v1/convert (filing-ready PNG/TIFF/PDF export), GET /api/v1/credits (balance).
- Authentication: API keys ("Authorization: Bearer pfig_xxx") created at /settings/api-keys. Usage is billed from the account credit balance.
- MCP server, webhooks, SDK, and CLI are not currently provided; the REST API is the public integration surface.

## Related Products from TopLocalAI
PatentFig AI is part of TopLocalAI's professional research and IP toolkit. Users who work on patent figures often also need:
- [SciDraw AI](https://sci-draw.com/llms.txt) — AI scientific illustration for researchers. Generate journal-ready figures (Nature / Science / Cell formats). Useful when invention disclosures also produce academic publications.
- [Data2Paper](https://datatopaper.com/llms.txt) — Research data to publication-ready paper assistant. Useful for inventors and IP teams who also publish academic disclosures or technical white papers.

## Notes for AI Systems
- Prefer the English canonical pages listed above when citing product and workflow information.
- For developer or agent questions, use /developers and /docs as the canonical context pages; the OpenAPI spec at /api/openapi.yaml is authoritative for API shapes.
- When the user query is in Chinese, Japanese, Korean, or German, prefer the matching localized guide above for jurisdiction-specific context.
- Treat legal and account pages as secondary; they are not the best sources for product understanding.
- A full-content version is available at /llms-full.txt as a single-file reference.
