Four things that work with no account.

Each one runs against the production API from your browser, on the same 50-render keyless trial an agent gets. Nothing is simulated, nothing is watermarked, and the files are yours.

JSON to PDF playground Paste an HTML template and a JSON payload, press render, get a PDF. The same round trip your code will make, with the template stored on a real account. PDF or PNG
Invoice generator Fill in a seller, a buyer and some line items. Totals, tax and payment terms are computed by the template, not by you. PDF
Certificate generator Course completion, completion of work, or a workmanship warranty. Landscape Letter, bordered, with a seal and signature lines. PDF
OG image generator A 1200×630 social card rendered on the Satori fast path. The same template this site uses for its own share images. PNG

How the trial works

Your browser gets an opaque client id, stored locally, and the MCP server mints a 50-render account against it. No email, no card, nothing to cancel. When you want more, the same account is upgraded in place — see getting a key.
