Accept an XMR/ZEC payment INTO YOUR OWN WALLET: creates a checkout invoice against your Private Watch (your address, your view key). Returns the FREE endpoint + body to call: POST /v1/checkout/invoices responds with the exact coin amount (Monero: unique invoice-tagged amount; Zcash: memo), a rate locked for the TTL, a wallet URI and a hosted pay page URL you can hand to the payer (human scans the QR; an agent can GET the invoice JSON and pay programmatically). When the payment confirms you get an invoice_paid webhook signed with your existing watch secret, and a flat settlement fee (~$0.02) is debited from the watch credit meter — never a percentage. Use your watchId+watchToken server-side, or a restricted checkoutKey (mint one with POST /v1/checkout/keys) anywhere you cannot keep secrets.
