Strike API
Strike API is an HTTP-based REST-style API for programmatic cash and bitcoin transactions.
What Strike API is
Strike API is an HTTP-based REST-style API for programmatic cash and bitcoin transactions. It supports sending, receiving, exchanging, and directing payments over the Bitcoin blockchain and Lightning Network, as well as payouts to external bank accounts. Businesses can accept incoming funds through invoices or receive requests, with balances credited to their Strike account as cash or bitcoin. OAuth Connect lets Strike users authorize third-party applications to make API calls within the permissions and scopes granted; webhooks can notify applications about supported events. Authentication uses either a non-expiring account API key or an expiring OAuth access token. The browser-based API Explorer can send requests and provides examples in cURL, Go, Python, and Node.js. A sandbox uses simulated cash balances and testnet bitcoin, and developers must contact business support to get set up. Production limits include 250 requests per minute for invoice creation and payment quotes, and 1,000 requests per 10 minutes for other endpoints; limits may change. Business or organization access requires a business account in a supported region and completed verification. Pricing is available on request.
