Overview

AI-generated overview

Remote render API that lets an assistant generate on-brand images from HTML/CSS templates and screenshot public web pages.

What you can do
List available image templates and the variables each accepts, free of charge, to pick a template id before rendering. Render an image from a chosen template and supplied data, returning the image and its cost. Capture a screenshot of any public web page and return the image.
When to use it
Useful when an assistant needs to produce Open Graph images, social cards, certificates, invoices or charts from templates, or to snapshot a live web page, without running a headless browser or installing fonts.
Requirements
A remote endpoint at api.propzapi.com over streamable HTTP. A propzapi API key is needed, supplied as the X-API-Key header (the README uses the PROPZAPI_KEY environment variable); a free trial key gives 50 images without a card. Network access is required.
Before you install
Rendering and screenshots are paid: 1 credit per image or screenshot, with plans from $29/mo and credit packs, so usage spends money. The API key is a credential and should be kept private. You are responsible for the content you render and for the rights to assets, fonts and pages you screenshot, and must comply with the terms of sites you capture.

Installation

In SourceWeft

  1. Open Propzapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.paperandbeyond23-gif%2Fpropzapi/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

propzapi-skills

Agent skills for template-based image generation and webpage screenshots. Drop-in skills that let any agent render an image from an HTML/CSS template, snapshot any live URL, and manage a template library — over the propzapi REST API.

Templates are HTML/CSS with {{variables}} and Jinja logic ({% if %}, {% for %}, filters). Fill the variables with one JSON call and get back a rendered PNG/JPEG/WEBP/PDF at a stable URL — no headless browser to run, no fonts to install. Perfect for Open Graph images, social cards, certificates, invoices, receipts, and data charts.

Free to start — grab a key (50-image trial, no card required) and you're rendering from Claude, Cursor, Cline, or your own agent loop in under two minutes.

Pure Python standard library. No dependencies. MIT-0 licensed.

Authentication

Set the PROPZAPI_KEY environment variable to your propzapi key. It's sent as the X-API-Key header — the base URL is hardcoded, so the key never reaches any other host.

bash
export PROPZAPI_KEY="your_key"

Get a free key — 50-image trial, no card required. You can also mint one with POST /v1/register → {api_key, plan, credits}. The same key works for these skills and direct REST calls.

Pricing

Each rendered image or screenshot costs 1 credit — the response returns the exact charge in the X-Credits-Cost header, and your balance in X-Credits-Remaining. Listing and creating templates is free.
