Need current numbers? Force an always-fresh scan (cache bypass) — pay in USDC via x402; the 402 challenge tells your client the price:

curl -X POST https://api.x402lint.dev/v1/scan \
  -H 'content-type: application/json' \
  -H 'x-payment: <YOUR_X402_PAYMENT>' \
  -d '{"url":"https://3fe290f1f310dc86f98e396f7003857d.serveo.net"}'
