B2BINPAY vs Strike API

B2BINPAY lets businesses send, receive, convert, and accept cryptocurrency payments online. Its payment service supports acceptance in 350+ currencies and combines payment processing with wallet as a service. Businesses can integrate through an API, use a hosted payment page or ecommerce plugin, or add a ready-made payment button to a website or app, including WordPress. Payment settings can be configured and tested in a sandbox without fees. The fee page lists immediate settlement for crypto and T+1 settlement for fiat. Listed safeguards include 2FA, address whitelists, user rights, wallet thresholds, blockchain risk scoring, third-party audits, and transaction screening for suspicious activity. Fees depend on incoming monthly volume and currency type; the listed Coins plan has incoming rates from 0.40% at $0–1 mln to 0.25% above $5 mln, with outgoing fees at 0.00%. Fiat deposits are accepted only through corporate bank wire. B2BINPAY is available on web and via API, with 24/7 customer service and API documentation listed for merchants.

Strike API is a paid, HTTP-based REST-style API for programmatic cash and bitcoin transactions. It works across the Bitcoin blockchain and Lightning Network, with cash payouts to external bank accounts. Businesses can send, receive, exchange, and direct payments, create invoices or receive requests, and credit incoming funds to a Strike account as cash or bitcoin. Checkout options include Lightning invoices, on-chain Bitcoin addresses, QR codes, and receive requests; settlement can be cash, bitcoin, or both. OAuth Connect lets users authorize third-party applications within granted permissions and scopes, while webhooks notify applications about supported events. Authentication uses a non-expiring account API key or an expiring OAuth access token. The browser API Explorer can send requests and supplies cURL, Go, Python, and Node.js examples. A sandbox uses simulated balances and testnet bitcoin. Business accounts, regional availability, and verification are required. Pricing is on request.
