TaxToolSet API early access
We are preparing API access for software teams that need structured tax rules, calculator outputs and source-aware tax data. Public API credentials are not being issued yet; this page records demand and use cases so the API can be designed around real integration needs.
Planned direction: versioned tax rules, calculation endpoints, source metadata, effective dates, country/jurisdiction scope and predictable machine-readable responses.
