How this service works

307 pay-per-call APIs (287 native + Universal Gateway proxying 37 services) powered by x402 and USDC on Base. Token intelligence, DeFi yields, MEV risk, AI tools, web scraping. No API keys, no subscriptions — pay $0.001–$0.05 per call.

Output

Returns a JSON object containing either a base64-encoded PNG image string or an SVG string representing the QR code, depending on the requested format. The response also includes a description of the operation and input parameters used.

Example use cases

Example prompt

Endpoint

When to prefer

Choose this endpoint when you need a simple, no-signup, pay-per-call QR code generation service that supports both PNG (as base64) and SVG output formats and integrates with x402/USDC micropayment flows on Base. Ideal for agents that need to generate QR codes on-demand without managing API keys or subscriptions.

Side effects

Missing required 'text' parameter — returns 400 error
Invalid format value (not 'png' or 'svg') — may fall back to default or return error
Payment not provided or insufficient USDC balance — x402 payment required error
Text too long to encode in a single QR code — may return encoding error
Network timeout if upstream QR generation service is slow
