AI Sign Designer Available Now on API and MCP

The AI sign designer now works through the Sign Customiser API and through AI agents. Send a PNG, JPEG or WebP image of 5 MB (5,242,880 bytes) or less. The AI sign designer makes a sign design and gives you the production files. A delivered design uses one credit. A design that fails uses no credit.

What’s Changed

• Make a design with the API. Send an image and start a design job. Read the job until the design is ready. The API makes neon, channel letter and metal cut-out designs.
• Get production files. Each design has an SVG file, an EPS file and an Illustrator-compatible PDF file. To get only the SVG file, ask for SVG only.
• Share files with no login. Each ready file has a download link. The link needs no API key and no login. You can give it to a manufacturer.
• Pay for delivered designs only. The AI sign designer holds one credit when a design starts. It uses the credit when the design is delivered. It releases the credit when the design fails.
• Send a request again with no second charge. If you send the same request again with the same Idempotency-Key, you get the same job. You use no second credit.
• Retry a failed conversion for free. If an EPS or PDF conversion fails, you can start it again. Each design has 3 free retries.
• Use an AI agent. Seven new MCP tools let an agent check the credits of the Store, send your image, start a design and get the files. Claude Code, OpenAI Codex and ChatGPT can use them.
• Confirm the credit first. Before an agent starts a design, it must confirm that the design uses one credit.

PNG files with a non-standard colour profile

Before this fix, the API and the MCP server could reject a valid PNG file that has a non-standard colour profile. Older Adobe exports often have this profile. The API and the MCP server now accept these files. They still reject a damaged file.

Get started

1. Create an API key in Tools & Settings > API Tokens. Select the ai_sign_designs:read and ai_sign_designs:write scopes. A key that you made before with a fixed list of scopes does not have these scopes.
2. Follow the AI sign designer guide.
3. To use an AI agent, follow the connection guide. Approve View AI sign designs and Use the AI sign designer. If you connected the agent before, connect it again.
