PDFPipe: The document API for developers and agents
Johin714 · 2026-06-11 · via Show HN

Code in. Document out.

Markup goes in. Paper comes out.

A document API for developers and agents. One request turns your markup into a pixel-perfect PDF: invoices, reports, certificates, statements. No print server to babysit on your own machines.

500 free documents a month. Free forever, no card, no trial, no expiry.

500

free documents / month

20+

languages and frameworks

14-day

refund, no questions

The render console

Edit the source. Watch it render.

This runs against the live API, right now. Change the markup on the left, render the document on the right. Ten free renders a day, no account needed.

The pipeline

One call in. A rendered document out.

No print servers, no font wrangling, no queue to operate at month-end.

  1. 01

    SEND

    POST your HTML, a URL, or a saved template with JSON data. Plain curl, or the Node and Python helpers.

  2. 02

    RENDER

    We render in an isolated, locked-down environment. Fonts, page breaks, headers, and footers are handled for you.

  3. 03

    RETURN

    The raw PDF streams back in about a second, ready to hand to your user or save to your storage. Add a flag to get a hosted URL with a retention window too.

  4. 04

    KEEP

    Documents stay retrievable based on your plan: one day on Hobby, up to two years on Scale. Re-download or stream them whenever you need.

Works where you work

One API, every workbench.

Official libraries and integrations, all open source, all one install away.

REST API

Any language, three lines of curl. The whole reference fits on one page.

curl https://api.pdfpipe.xyz/v1/pdfRead the docs →

Node.js

Typed SDK for Node 18+, Bun, and edge runtimes. Returns bytes plus your live usage.

npm install pdfpipe-nodeView on npm →

Python

One class, two methods. Plays nicely with Django, FastAPI, and plain scripts.

pip install pdfpipe-pythonView on PyPI →

n8n

Drop PDFPipe into any workflow: invoice on order, certificate on signup, no code.

AI agents · MCP

Give Claude, Cursor, or any MCP client the power to produce real documents.

Spec sheet

Built like infrastructure you can actually trust.

Four things matter when documents are part of your product: how they look, what they cost, how safe the render is, and whether your agents can wire it up unattended.

500 documents a month, free, forever. Ten times the usual allowance, because side projects deserve real limits.

  1. 01 / OUTPUT

    Pixel-perfect page geometry

    Real A4 or Letter, true margins, repeating headers and footers, page numbers, embedded fonts. It looks printed because it is rendered like print, not screenshotted.

    A4 · Letter · customheaders · footersembedded fonts

  2. 02 / TRUST

    Flat pricing, no surprises

    A document is a document. No credits, no size multipliers, no overage ambushes. The number on this page is the number on your card, every month.

    no creditsno multiplierscancel anytime

  3. 03 / SECURITY

    Sandboxed by default

    Each render runs isolated, with no credentials and no route to private networks. Document services are a classic attack target. Ours is built like one.

    isolated renderno private network accessno stored secrets

  4. 04 / AGENTS

    Built for AI agents

    A first-class agent integration and docs a copilot can wire up in one shot. When your assistant adds invoicing, it reaches for this.

    one-shot setupstructured errorsidempotent calls

Use cases

Common patterns, ready to ship.

One API, any document. These are the patterns teams reach for most often.

Pricing · live now

One price. As many documents as you said.

Pick a tier, get your key the moment payment clears, render in minutes. Every plan includes the full API and the document archive.

Fair questions

Before you wire it in.

Can I not just render PDFs myself?

You can, and many do, until the 2 a.m. incident where it leaked memory and took checkout down with it. We handle the rendering engine, queues, retries, and font loading so your team ships product instead of operating document infrastructure.

How is this different from converter sites?

Those are for a person converting one file. PDFPipe is for software that creates documents on its own: every order, every signup, every month-end, with data filled in and nobody clicking anything.

What happens if I go over my monthly limit?

Requests that exceed your limit return a clear 402 error so your code can handle it gracefully. You can upgrade at any time and your limit resets immediately. We never silently drop requests or surprise you with overage charges.

Is there a refund policy?

Yes. If you are not satisfied within the first 14 days, email [email protected] and I will refund you in full, no questions. After that, you can cancel any time and keep access through the end of your billing period.

What languages and frameworks does it support?

Anything that can make an HTTP POST request. The core API works from curl, Node.js, Python, Ruby, Go, PHP, Java, Rust, Elixir, and any other language. We publish first-party SDKs for Node.js and Python. Everything else uses plain fetch or your language's HTTP client.

Can I store documents and share download links?

Yes. Add store: true to any render request and the PDF is stored in our CDN for the retention period on your plan. You get back a document ID and a pre-signed URL. You can also query document metadata (filename, size, expiry) without downloading the full file.

A note from the founder

I build document pipelines for a living, and every company I have worked with ends up with the same haunted corner of the codebase: the PDF service. Nobody wrote it on purpose. Nobody wants to touch it. It falls over on the last day of the month, exactly when finance needs it.

PDFPipe is me fixing that once, properly, for everyone. Small team, no investors to impress, no plan to get acquired and sunset your integration. If it ever shuts down, you get a year of notice and an export button. In writing.

Questions go straight to [email protected]. I answer everything myself, usually same day.
