+  summary: Quote single payment intent
+  description: |
+    Calculates quote for one payment intent without executing payment. The response includes
+    `quote.executable`, `quote.state`, and optional `quote.blockReason` so clients can reject
+    non-executable quotes before attempting execution. Raw `card` destinations can omit expiry
+    while quoting, but quotes intended for later execution should include `exp_month` and
+    `exp_year`. Card-recipient AML screening is not performed during quotation; it runs during
+    payment execution, so an executable quote does not guarantee AML acceptance.
