How this service works

Fast deterministic developer utilities for AI agents, paid per call in USDC via x402 (no account, no API key): UUID v4/v7, secure random numbers, dice, MD5/SHA/HMAC hashing, base64/hex/URL/HTML encoding, JSON validation/formatting, QR code SVG, password generation, JWT decoding and text statistics. Pure computation, nothing stored. Errors are never charged.

Output

Returns a JSON object containing the rendered QR code as an inline SVG string, a base64 data URI for direct embedding, the number of modules (grid cells), the actual rendered pixel size, and the QR version number used.

Example use cases

Embed QR code on product page

“Create a QR code for https://store.example.com/product/42 at 256px with medium error correction and return it as JSON so I can drop the SVG straight into my product page.”

Print-ready QR with high error correction

“I need a QR code for the text 'Join our Wi-Fi: Network=GuestNet Password=Welcome123' — use high error correction and make it 512px so it stays readable if the print gets a bit smudged.”

Link shortener landing QR code

“Make a QR code for https://bit.ly/my-event-2025 at the default 256px size and return the SVG so I can paste it into my email newsletter template.”

When to prefer

Choose this endpoint when you need a fast, no-account, no-API-key QR code generated on demand and billed micropayment-style via x402 USDC. Ideal for AI agents that need embeddable SVG or data-URI QR codes without setting up OAuth or managing API keys. Prefer it over heavier QR services when you want pure computation with deterministic output, zero stored state, and errors that are never charged.

Side effects

Missing required 'text' query parameter returns an error (not charged)
'size' out of range (64–1024) returns a validation error (not charged)
Invalid 'ecc' value returns an error (not charged)
Text too long for the requested QR version may return an encoding error
Network timeout on the Cloudflare Worker edge (rare)
