Technical details
Endpoint
GEThttps://api.gocreativeai.com/v1/calc/sales-tax-reverse/%7Barg%7DWhen to prefer
Use this endpoint when you need to reverse-engineer a known total that already includes sales tax to find the original pre-tax price and the tax component — especially useful for receipt parsing, accounting reconciliation, and e-commerce refund calculations. Prefer this over a forward sales tax calculator when the total (not the base price) is the known quantity.
Side effects
- Invalid or missing input argument returns a 400 or error JSON
- Non-numeric or malformed total amount causes a computation error
- Unknown jurisdiction or tax rate identifier returns no result or error
- Payment not received (402 Payment Required) if USDC micropayment not included
- Rate limiting or service unavailability returns 5xx error
