How it works

Buy a pack in the shop.
Come back to https://api-keys.restockalarm.workers.dev/claim and enter your order number + email → you get your API key (shown once).
Send it as header X-API-Key.

curl -H "X-API-Key: sck_…" "https://header-audit.restockalarm.workers.dev/api/report?url=https://example.com"

Check balance: GET https://api-keys.restockalarm.workers.dev/balance with header X-API-Key.

USDC on Base (x402 / pay page) keeps working without a key.
