+  summary: Initiate payment from immediate intent
+  description: |
+    Creates quote and executes a single payment in one call (request must include `intent`). For
+    raw `card` destinations, execution requires `exp_month` and `exp_year`; `cardToken`
+    destinations only require `token`. Card-recipient AML screening occurs during execution.
+    An unchanged payment reuses its persisted compliance decision on idempotent execution replay,
+    avoiding a duplicate AML call. A definitive denial terminates the payment with public
+    `failureCode: failure_restriction` and `failureReason: aml_denied`.
