API

API for Bitcoin payments, wallet management & transaction data

Overview

The Blockchain API provides RESTful endpoints for Bitcoin payment processing, wallet balance checks, transaction history retrieval, and address validation. It returns data in JSON format, enabling developers to build crypto payment gateways, track real-time transaction trends, integrate wallet services into apps, and automate Bitcoin payment workflows. Basic public endpoints offer free access, while advanced features like high-volume payments or dedicated support require authentication and paid tiers.

  .catch(err => console.error(err));
