Quickstart - markdown2pdf.ai

Here’s a few examples of how to use markdown2pdf.ai in your code.

Python
Typescript
MCP
X402 (Python)

pip install markdown2pdf-python

from markdown2pdf import MarkdownPDF

def pay(offer):
    print("⚡ Lightning payment required")
    print(f"Amount: {offer['amount']} {offer['currency']}")
    print(f"Description: {offer['description']}")
    print(f"Invoice: {offer['payment_request']}")
    input("Press Enter once paid...")

client = MarkdownPDF(on_payment_request=pay)
path = client.convert(markdown="# Hello from Python", title="My document title", download_path="output.pdf")
print("Saved PDF to:", path)

npm install @serendipityai/markdown2pdf-typescript

import { convertMarkdownToPdf } from "@serendipityai/markdown2pdf-typescript";
import type { OfferDetails } from "@serendipityai/markdown2pdf-typescript";

async function pay(offer: OfferDetails) {
  console.log("⚡ Lightning payment required");
  console.log(`Amount: ${offer.amount} ${offer.currency}`);
  console.log(`Description: ${offer.description}`);
  console.log(`Invoice: ${offer.payment_request}`);
  await new Promise<void>(resolve => { process.stdin.once("data", () => { resolve(); }); });
}

async function main() {
  const result = await convertMarkdownToPdf("# Hello from Typescript", {
    title: "My document title",
    downloadPath: "output.pdf",
    onPaymentRequest: pay
  });
  console.log("Saved PDF to:", result);
}

main().catch(console.error); 

You can drop the below configuration in to your Claude MCP config to add PDF conversion to your chat workflow.

"mcpServers": {
  "markdown2pdf": {
    "command":"npx",
    "args": ["@serendipityai/markdown2pdf-mcp"],
    "cwd": "~"
  }
}

pip install "x402[httpx]" solders

import os, asyncio
from solders.keypair import Keypair
from x402 import x402Client, prefer_network
from x402.http.clients.httpx import x402HttpxClient
from x402.mechanisms.svm import KeypairSigner
from x402.mechanisms.svm.exact import ExactSvmScheme

async def main():
    keypair = Keypair.from_base58_string(os.environ["SOLANA_SIGNER_KEY"])
    signer = KeypairSigner(keypair)
    NETWORK = "solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp"
    x402 = x402Client()
    x402.register(NETWORK, ExactSvmScheme(signer=signer))
    x402.register_policy(prefer_network(NETWORK))
    async with x402HttpxClient(x402, timeout=120.0) as client:
        resp = await client.post(
            "https://api.markdown2pdf.ai/markdown",
            json={
                "data": {"text_body": "# Hello from X402"},
                "options": {"document_name": "hello.pdf"},
            },
        )
        resp.raise_for_status()
        print("Paid tx proof:", resp.headers.get("payment-response"))
        print("Poll:", resp.json()["path"])

asyncio.run(main())

The x402HttpxClient handles the 402 → sign → retry loop for you. See the X402 page for details and manual-flow variants.

You’ll see that, in general, you pass your markdown content, a title and a download path to the convert function and it will handle the markdown conversion for you. A mandatory function must be provided which is used to handle the payment using a mechanism of your choice — either Lightning via L402 or USDC on Solana via X402. This could be a manual payment (copy-and-paste the Lightning invoice into a wallet of your choice, or sign an X402 X-PAYMENT header with a Solana wallet), but more likely will be handled programmatically via a Lightning wallet or a Solana signer.
