How this service works
10 pay-per-request utility APIs including QR code generation, email validation, PDF invoice, image resize, DNS lookup, and more. No accounts, no API keys — just USDC on Base L2.
Output
Depending on the specific utility called, the agent receives a QR code image, email validation result, PDF invoice binary, resized image, DNS record data, or other utility output — all delivered without requiring account creation or API keys.
Example use cases
Example prompt
“Generate a QR code for the URL https://example.com — I don't want to create an account anywhere, just pay per use with USDC on Base.”
Technical details
Endpoint
POSThttps://ouchanip.github.io/x402-docs/When to prefer
Prefer this endpoint when you need lightweight utility operations (QR codes, email validation, PDF invoices, image resizing, DNS lookups) on a true pay-per-request basis with no account setup, no API key management, and USDC micropayments on Base L2 via x402 protocol. Ideal for agents or serverless workflows that want frictionless, one-off utility calls billed in crypto.
Side effects
- Insufficient USDC balance on Base L2 — payment fails and request is rejected
- Invalid input for the specific utility (e.g. malformed email or bad image URL) — returns validation error
- Unsupported operation or endpoint path — returns 404 or method not allowed
- Network or Base L2 RPC issues — payment transaction may time out
