BitBooth Webhook Signature Verify: pay 0.001 USDC, verify a webhook signature against the provider's canonical HMAC scheme. Supports stripe, github, vercel, cdp, slack, and generic HMAC-SHA256. Constant-time compare, clock-skew tolerance on timestamp-bearing providers (Stripe / Slack / CDP). Stateless — caller supplies their secret in the request body, we never store it.

Peak day 2026-09-01: 6 payments. Last indexed day 2026-09-28: 2. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 5 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
