Cryptocurrency — entry 029 of 53
CryptAPI
CryptAPI (by BlockBee) is a non-custodial crypto payment gateway that lets merchants accept 50+ cryptocurrencies — including Bitcoin, Ethereum, Litecoin, Dogecoin, Solana, and stablecoins like USDT/USDC across Ethereum, BSC, Polygon, Arbitrum, Avalanche, Base, and Optimism — with no signup or API key required. Funds settle directly to the merchant's own wallet, and payment confirmations arrive as webhook callbacks rather than through a polling endpoint. The service charges a flat 0.25% fee per transaction instead of a subscription.
