Coverage checks

Check whether the API supports a country, item tax code, transaction type, and effective date for a specific calculation.

Check one transaction combination

Send a country, optional subdivision, item tax code, transaction type, customer type, and date. Coverage returns the qualification for that exact combination. A country appearing in the response does not mean every item or customer type is supported.

Request

Shell

curl --request GET \
  --url "https://api.salestaxcalculatorapi.com/v1/coverage?country=CA&state=ON&tax_code=saas&transaction_type=sale&customer_type=consumer&date=2026-08-29" \
  --header "Authorization: Bearer $SALESTAX_API_KEY"

A calculation request returns its own outcome. You do not need to call coverage first.
