About Coinremitter

Coinremitter provides a Bitcoin payment API for businesses to accept BTC payments on their websites. The API supports creating and managing wallet addresses, validating addresses, estimating withdrawal costs, processing withdrawals, retrieving transaction and balance information, and generating invoices with payment tracking. It also includes webhook/IPN notifications for wallet and invoice events.

Beyond the core API, Coinremitter offers several embeddable widgets: a pricing widget for displaying auto-updated rates, a presale widget for early-access sales with countdowns and tiers, a payment button widget for one-click payments or donations, and a hosted payment page widget for checkout. Plugins are available via the company's GitHub account.

The service is aimed at developers and business owners integrating Bitcoin payment processing into checkout flows. API access requires a key and password, with rate limits of 100 requests per minute on the free plan and 500 on the Pro plan; higher limits are available by contacting the company. All API responses use UTC timestamps.
