# propzapi
> The image generation API for developers and AI agents. Give it a template and
> your data, get back a PNG, JPEG, WebP or PDF — over REST or as an MCP tool.
propzapi renders your own HTML/CSS templates into images with headless Chromium.
Thirteen templates ship built in, including data-driven bar/line/donut charts. Pure compute, no third-party data vendor.
## Endpoints
- POST /v1/images · render an image (or PDF) from a template + your data
- POST /v1/screenshot · screenshot any public URL to an image
- POST /v1/embed-url · sign a GET render URL for (cached, free on refetch)
- POST /v1/templates · create a reusable template (HTML with {{variables}} + {% if %}/{% for %})
- GET /v1/templates · list built-in and your own templates
- POST /v1/templates/preview · render without charging (editor live preview)
- POST /mcp · MCP server: generate_image, screenshot_url, list_templates
- POST /v1/register · get a free API key (50-image trial, no card)
## Why propzapi
- Agent-native: generate_image / screenshot_url return the image to the agent, not just a link
- Real templating (sandboxed Jinja2): {{ var }}, {% if %}, {% for %}, filters — data becomes tables/lists/charts, not just fill-in-the-blank
- Embed URLs: a template becomes a signed URL you drop into ; renders once, cached free after
- Your own HTML/CSS templates, edited with live preview, no no-code editor
- Built-in templates: social cards, quotes, thumbnails, testimonials, stats, tickets, code cards, certificates, stories, and data charts
- One credit per image, billed on delivery, exact cost in the X-Credits-Cost header
