Strike API review
A focused API for developers building Bitcoin, Lightning, and cash payment flows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Strike API is an HTTP-based payments API for businesses and developers building programmatic Bitcoin, Lightning, and cash transaction flows. It supports receiving Bitcoin and cash payments, sending Lightning and on-chain Bitcoin payments, creating fixed-amount invoices, and creating flexible receive requests. Merchants can present Lightning invoices, on-chain Bitcoin addresses, QR codes, or receive requests to payers, with settlement available in Bitcoin or supported cash currencies.
The commercial model requires contacting sales. No public pricing or standardized merchant transaction fee is presented, while transaction-based fees may apply and may be confidential or agreed separately. That makes Strike API better suited to teams that can evaluate business terms directly than to developers comparing transparent self-serve plans. Its platform fit centers on API and web access, with OAuth listed for third-party integrations. API-key and OAuth authentication provide two defined access paths, while webhook notifications can communicate payment events to connected systems.
The standout strength is breadth within Bitcoin and Lightning payments: receiving, sending, invoicing, exchange quotes, and bank payouts are covered in one API. Currency-exchange quotes extend the workflow beyond basic payment acceptance, and cash payouts connect payment activity with bank-account disbursement. Strike API is a strong match for developers who want to assemble Bitcoin and Lightning payment flows around these capabilities. It is less suitable for teams seeking published pricing, broad verified integrations, or a ready-made checkout experience without direct API implementation.
