The 402 Install — CAD 750
This check tells you what is wrong. The install puts a payment-required path in front of up to three of your endpoints, in your own Cloudflare account, and proves it works: a before-and-after report, one real settlement of USD 0.01 on Base with the transaction hash, a CI check that fails the build if the 402 body drifts, and fourteen days of bug fixes.
CAD 275 for the diagnosis alone, credited against the install within 30 days. Delivered in three business days from access. If delivery runs past three days, half is refunded automatically.
