"input": {
"couponCode": "SAVE10",
"expiryDate": "2026-11-01",
"asOfDate": "2026-11-01"
},

}Limitations and assumptions
- The expiry date itself is included; timezone, time-of-day, eligibility, exclusions, issuer authority, and actual offer terms are not checked.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Check actual offer terms, item eligibility, taxes, and monetary rounding before applying a computed price.
