Welcome to Hoseki’s API documentation. These docs are designed to help developers seamlessly integrate Hoseki’s capabilities into their applications, making it easy to verify and manage Bitcoin holdings across the two primary ownership methods: self-custody and exchanges.

Verify API Copied

The Verify API allows users to securely connect self-custodial wallets, view real-time balances, and generate verified ownership statements. Unlike standard wallet integrations, Verify goes a step further—it cryptographically proves ownership of each connected wallet, ensuring your users truly control the Bitcoin they’ve linked.

To get started, check out our Verify API guides.

Hoseki Connect Copied

For assets held on exchanges, Hoseki Connect provides a robust integration layer across a growing number of platforms. It delivers a unified portfolio view by consolidating exchange data—without the overhead of managing multiple APIs.

To get started, please follow our Integrating Hoseki Connect guide.
