quickchart.io
QuickChart is a web service for generating static chart and QR/barcode images from HTTP requests. It is used to render Chart.js charts and related assets for emails, reports, automation, and other environments without client-side rendering.
QuickChart exposes one HTTP API, documented by an OpenAPI spec at `https://quickchart.io/openapi.json`, covering chart rendering, QR generation, QR batch generation, QR reading, validation, and natural-language chart config generation; no GraphQL, MCP server, or first-party CLI surfaced.
- QuickChart APIdetected
Sign up for a paid QuickChart plan from Pricing. Per the auth docs, you receive an API key and account ID upon signup; use the API key directly in requests as key, or as the secret when generating signed URLs with your accountId. The docs say authenticated requests bypass rate limiting and unlock paid features.
