What is the Nocturne Playground?

A keyless sandbox to test every Nocturne document API endpoint — generate PDFs, render screenshots, enrich metadata, and extract text, tables, markdown, and OCR from documents — with no signup.

Do I need an API key to use the playground?

No. The playground is keyless and rate-limited to 3 requests per IP per day. For production use, get an API key from the dashboard.

Nocturne Playground — try the document API, free

Nocturne is a document API for developers and AI agents. Test all four endpoint families below with no signup and no API key — then get a key when you are ready to build.

Generate — HTML or URL to pixel-accurate PDF (POST /v1/generate/pdf).
Render — full-page screenshots with device emulation (POST /v1/render/image).
Enrich — structured metadata, OpenGraph, and readable content (POST /v1/enrich).
Extract — text, tables, Markdown, and OCR from documents (POST /v1/extract/*).

Keyless access is rate-limited to 3 requests per IP per day. Usage is metered in credits, settled in self-custodied stablecoins.

Try the API, no code.

Upload a document and see the JSON any developer or agent would receive. Three free requests per day, per device — then create a free account for 100 credits a month.
