What It Is

LimeTip is a VAT Validation API provided by Sweden-based LimeTip AB. Its core purpose is to help businesses validate European VAT numbers. Designed for developers, it returns structured JSON via a REST API, including whether the VAT number is valid, company name, address, country code, VAT number, and last validation time. It is well suited for integration into registration, invoicing, B2B transactions, and tax compliance workflows.

Core Features and Developer Experience

Based on the available information, LimeTip’s main strength is its simple API design: authentication is handled via an API Key, and VAT numbers can be validated with a GET request. The response fields are straightforward. The website provides a JavaScript fetch example and mentions type definitions for TypeScript users. The official site highlights sub-100ms responses, globally distributed infrastructure, 24/7 monitoring, and a 99.99% uptime SLA. However, the terms of service also state that it depends on Railway and external APIs, so real-world reliability should still be load-tested before production use. Coverage is advertised as 27+ EU Countries, with a clear focus on European use cases.

Pricing and Commercial Terms

Pricing is relatively transparent: the free plan includes 250 requests per month but is limited to 1 request/min; Starter/Business costs €25/month with 10,000 requests; Professional costs €95/month with 50,000 requests. The enterprise plan supports custom usage, dedicated support, SLA, an account manager, IP whitelisting, and custom reports. Annual billing saves about 17%, and a 30-day money-back guarantee is offered. For payments, major credit cards are supported, while enterprise customers can arrange bank transfers. Subscriptions are created through Stripe.

Pros and Cons

The advantages are a clear API model, a usable free tier, response data that can be directly integrated into business systems, and email or priority email support. Enterprise features such as custom rate limits, request logs, IP whitelisting, and SLA also cover common requirements for compliance systems. The drawbacks are that the service is currently in early access, requiring an email application and manual review; API Keys are usually issued within 24 hours, so onboarding is not fully self-service. There is also no disclosed information about open source availability, self-hosting, or official SDKs, and the ecosystem still appears to be at an early stage.

Who It’s For and Access from China

LimeTip is suitable for cross-border SaaS platforms, e-commerce businesses, financial systems, ERP products, or development teams that need to validate EU customer VAT numbers. It is less suitable for companies that need global tax ID coverage, strong localized deployment, or offline private deployment. Access from mainland China is not described in the available text. Stripe payments and connectivity to overseas APIs may be affected by network conditions and corporate payment constraints, so it is recommended to test connectivity first using the free tier or a trial. Alternatives to compare include VIES, vatlayer, Vatstack, Taxually, and Stripe Tax.
