What both publish
| Fact | Complyt | ShipVAT |
|---|---|---|
| Address validation | The Address Validation API checks U.S. addresses against official postal databases and returns suggested matches with confidence scores. | Address endpoints validate and normalize addresses and expose supported countries and regional subdivisions. |
| Authentication | The API uses client ID and client secret credentials to obtain an Auth0 bearer token that expires after 24 hours. | API requests use Bearer-token authentication with separate sk_test and sk_live key formats. |
| Nexus thresholds | The transaction guide distinguishes estimates, which do not count against nexus thresholds, from invoices, which do. | The thresholds endpoint supports VAT registration, US remote-seller nexus, Canadian PST nexus and GST small-supplier threshold types. |
| Tax calculation | The API returns a calculated sales tax amount and the applicable rate. | The calculation endpoint accepts one to 100 line items and supports physical goods, digital goods, SaaS, services and streaming products. |
