**Show HN: DocFast – HTML/Markdown to PDF API with built-in invoice templates (100 free/mo)**

## Body

Hi HN,

I built DocFast (https://docfast.dev) — a simple API that converts HTML, Markdown, or URLs to PDF.

**Why I built it:** Every project I've worked on eventually needs PDF generation. Setting up Puppeteer, dealing with Chrome memory leaks in production, managing headless browser instances — it's always more painful than it should be. I wanted something where I could just POST some HTML and get a PDF back.

**What makes it different:**

- **Markdown endpoint** — most PDF APIs only accept HTML. DocFast has a native `/v1/convert/markdown` endpoint with syntax highlighting.
- **Built-in templates** — pass JSON data to `/v1/templates/invoice/render` and get a professional invoice PDF. No HTML required.
- **Fast** — persistent browser pool, no cold starts. Sub-second generation for most documents.
- **Privacy** — your data is never stored. PDFs are generated and streamed directly.

**Pricing:** Free tier gives you 100 PDFs/month with access to all endpoints and templates. Pro is $9/month for 10,000 PDFs.

**Quick example:**

```bash
curl -X POST https://docfast.dev/v1/convert/markdown \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"markdown": "# Hello World\n\nGenerated by DocFast."}' \
  -o hello.pdf
```

You can get an API key instantly at https://docfast.dev — just an email, no credit card.

I'd love feedback on the API design, pricing, or anything else. Happy to answer questions.
