About Vanta SDK
Building the payment layer for the programmable web.
Our Mission
We believe HTTP 402 Payment Required can transform how developers monetize APIs and how AI agents interact with digital services. Vanta SDK makes this vision practical with production-ready tools.
Why We Built This
Traditional API monetization is broken. API keys, subscription management, billing integrations—it's all friction that slows down developers and excludes entire categories of users like AI agents.
x402 payments offer a better way: direct, programmable, micropayment-friendly transactions at the protocol level. No middlemen, no subscriptions, no API keys.
Open Source
Vanta SDK is fully open source under the MIT license. We believe infrastructure this fundamental should be a public good. Contributions are welcome.
