About propzapi
What is propzapi?
propzapi is an image generation API built for developers and agents. Unlike design apps with APIs bolted on, propzapi provides a straightforward REST endpoint and a hosted MCP server. You post a template and your data, and the service returns a finished image in PNG, JPEG, or WebP format.
How does it work?
Send a POST request to the API with a template ID and a small object of values. The render engine, using headless Chromium, fills your placeholders and returns a URL to the finished image. The API is metered, and you're only charged when a render succeeds.
Who is it for?
propzapi is for developers and teams who need to generate images programmatically at scale. It's particularly useful for creating share cards, social media images, and dynamic visuals inside agent workflows using tools like Claude, Cursor, or n8n. It is not a design tool; it's a headless image generation service.
Real use cases
Generate 1200×630 share cards for blog posts, dynamic quote graphics, or personalized images for user notifications. Because it returns the image URL directly to an agent, it fits well in automated content pipelines and social media scheduling tools.
Key features
- Template-based rendering — Create an HTML/CSS template once, render it any number of times with different data.
- MCP-native — Integrates with Claude, Cursor, Cline, and n8n via a hosted MCP server.
- Multiple output formats — Render to PNG, JPEG, WebP, or PDF in one request.
- Credit metering — Only charged for successful renders, with exact costs returned in response headers.
- OpenAPI 3.1 & llms.txt — Standard, documented integration points for any HTTP client.
- Bring your own templates — Upload your own HTML and CSS if the built-in templates aren't enough.
