ShipVAT
ShipVAT provides an API for calculating VAT, sales tax, and GST across 93 jurisdictions. The maker lists the EU, UK, US, Canada, and Australia among supported regions, and describes economic nexus threshold intelligence for all 50 US states and beyond. API functions include tax calculations, rate and threshold lookup, transaction and customer management, VAT validation, compliance reports, webhooks, and address validation. ShipVAT says rates include a source URL, verification timestamp, and effective dates, with tax data curated from official sources. Developers can use a TypeScript SDK, OpenAPI 3.0, Swagger UI, and curl examples. Endpoints use Bearer-token authentication with test and live key formats. The API is described as working with Paddle, LemonSqueezy, PayPal, or any payment stack. The Free plan costs nothing and allows 100 API calls per month. Pro costs $49 a month for 50,000 calls; Enterprise pricing is custom and its listed call limit is unlimited.
