Invoices

Prices are fiat decimal strings; each accepted asset gets its own exact amount due. Deposit addresses are exclusive to the invoice but may be shared between its options: all of its EVM options use one address, the same on every EVM network. Requires an Idempotency-Key.

Only while nothing has been seen for it (awaiting_payment with no payment at all). The deposit address stops being offered and goes into its cooldown, where a transfer that still arrives is attributed to this invoice and becomes refundable. Idempotent: cancelling a cancelled invoice returns it unchanged. Sends invoice.cancelled.

An invoice is under_review when a payment was held for a person to look at (for example, one at or above the manual-review amount). accept credits what was held, exactly once, and the invoice moves on (usually to paid). reject cancels the invoice and leaves everything received refundable. Sends invoice.review_resolved and the status webhook (invoice.paid, invoice.cancelled, ...).

In live mode an API key may accept only amount-threshold holds (manual_review); accepting a risk hold (sanctions, blacklist, a finality violation) needs a person on the dashboard (review_requires_dashboard). Rejecting is always allowed.
