title: Cofferdock Validation API
version: 1.0.0
summary: 'One API key, 48 tools for automations: HTML to image or PDF, screenshots, QR codes, charts, PDF editing, image processing, validation and data helpers.'
description: 'All tools share one account and one monthly pool of credits (1 successful call = 1 credit; failed calls are not charged). Free plan: 50 credits a month, no card.
Authenticate with the header `x-api-key`. Most tools accept the input either as JSON (base64 for files) or as raw bytes (the file itself as the request body, options as query parameters), and can return the result as JSON (base64), as the file itself (`output=binary`) or as a temporary download link (`output=url`).
