How this service works
QR code generator — encode text, URLs, payment URIs, or arbitrary UTF-8 data as base64-encoded SVG or PNG in a JSON envelope.
Output
A JSON envelope containing the QR code image encoded as a base64 string in either SVG or PNG format, ready to be decoded and embedded in web pages, print materials, or applications.
Example use cases
Payment URI QR for crypto checkout
“Generate a QR code for this Bitcoin payment URI — bitcoin:1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf — and return it as a base64 SVG so I can drop it on my payment page.”
Event landing page QR code
“Make a QR code that encodes https://events.mycompany.com/conference2025 and return it as a PNG — I need to print it on our event badges.”
Wi-Fi credentials QR for office guests
“Create a QR code that encodes the Wi-Fi string WIFI:T:WPA;S:OfficeGuest;P:Welcome2025;; and give me back a base64 SVG so guests can scan it from a sign at reception.”
Technical details
Endpoint
POSThttps://visuals.use.x402atlas.com/qr?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a programmatic, pay-per-call QR code generator that handles URLs, payment URIs, and arbitrary UTF-8 text with no signup or API key — especially in agentic workflows where you pay per use via x402 USDC microtransactions and need clean base64 output for direct embedding.
Side effects
- Input data too long for QR encoding capacity — returns error indicating data overflow
- Unsupported output format requested — returns validation error
- Empty or missing input data — returns 400-level error
- Malformed UTF-8 input — encoding error returned
- Payment failure (x402) if USDC balance insufficient — request blocked before processing
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| data | string | Non-empty UTF-8 payload, at most 2048 encoded bytes and subject to QR capacity. |
| size | integer | Exact width and height of the square output canvas in pixels; must preserve at least one pixel per QR module. |
| format | string | Artifact format encoded into content_base64. |
| background | string | Opaque #RRGGBB canvas and quiet-zone color; must contrast with foreground by at least 4.5:1. |
| foreground | string | Opaque #RRGGBB color for filled QR modules; must contrast with background by at least 4.5:1. |
| margin_modules | integer | Quiet-zone width around the QR matrix, measured in whole modules. |
| error_correction | string | QR recovery level: L has the most payload capacity; H has the most damage recovery but the least capacity. |
