by | Oct 23, 2025 | Comparison, Informational, Problem-solving

If you take cryptocurrency payments, a crypto invoicing API connects blockchain transactions to the rest of your organization. It takes care of settlements in real time, sends out payment requests automatically, and verifies on-chain transactions.
BitLily makes it easy for freelancers and digital enterprises to send invoices, get paid, and settle payments using Bitcoin, Ethereum, or stablecoins. They don’t have to go through onerous KYC processes to do this.


1. Multi-Wallet Support

A good crypto invoicing API should be able to interact with a multitude of different blockchain wallets. This lets businesses get paid over the Bitcoin, Ethereum, USDT, or USDC networks.
BitLily’s payment gateway allows you accept crypto from any network, whether Bitcoin, Ethereum, Polygon, or Tron. It connects straight to multi-chain wallets.


2. Automated Settlements

Settlement is the point at which billing and finance meet. The API should automatically confirm transactions on-chain and transmit the money that has been paid to the merchant’s wallet.
With BitLily’s crypto-to-fiat settlement API, businesses may either maintain their assets in crypto or automatically shift them into stablecoins like USDT to keep them safe.


3. Callback Notifications (Webhooks)

Every time a crypto payment goes through, your system should get a quick call back to confirm that the invoice has been paid.
BitLily’s callback system uses secure webhooks to let merchants know about changes right away, so there are no double charges or missing confirmations.


4. On-Chain Transparency

One of the best things about blockchain payments is that they are clear.
You can trust BitLily’s on-chain payments API to keep track of all your invoices, transactions, and settlements on-chain. This is very significant for businesses and people who make things that use digital contracts.


5. Multi-Currency & Cross-Border Support

You should be able to make and receive crypto payments in more than one currency and across borders with a modern invoicing API. BitLily’s infrastructure enables customers get payments from anywhere in the globe, in any currency, and change them right away if they need to.


6. Security & Compliance

Even if you use BitLily’s no-KYC crypto API, your transactions are still entirely safe. End-to-end encryption, rate limiting, and fraud checks protect every API call. You may stay anonymous and still protect your money.


7. Integration Simplicity
