What is CryptAPI?
CryptAPI is a payment processor API, which allows you to create payment addresses for your customers on multiple cryptocurrencies easily
How does it work?
With a single line of code you can request a new payment address on any of the supported coins, you just need to provide the callback URL where you will be notified of the payment and the address where you want your payment forwarded to. Give that address to your customer, where he or she can issue the payment, and, as soon as the transaction is confirmed our system will forward the payment to you and notify your callback URL with the payment details (value, TXID in, TXID out, number of confirmations, etc)
How much do I pay to use your service?
You have no costs upfront, but we have a 1% fee in order to pay for our infrastructure.
Here is the full fee formulas for all the coins we support so far:
| Coin | Minimum Amount | Fee |
| Bitcoin | 0.0005 BTC | max(0.00025, 0.01 * amount) |
| Ethereum | 0.001 Ether | max(0.0005, 0.01 * amount) |
| IOTA | 0.5 MIOTA | max(0.25, 0.01 * amount) |
What is the "Minimum Amount"?
Means that payments below this amount are disregarded by our system and will not be forwarded.
These values may be updated in the future based on the coin's value and fees.
Where do I sign-up?
You don't! In our service we value your privacy, so there's no sign-ups, API keys or anything like that. All you need to request a new payment address is a callback URL and a Bitcoin/Ethereum/IOTA address.
Where can I read your documentation and try your API?
We have interactive documentation here that you can try for yourself.
How does your system work?
Here is the step-by-step ELI5 walkthrough:
- 1 - You request a new payment address from our API, with your destination address and callback URL (e.g http://example.com/callback?invoice=1234)
- 2 - You present your customer with the payment address generated by our system
- 3 - Your customer sends the amount to the payment address our system generated
- 4 - Upon confirmation our system forwards the payment to the address you provided when you request the address and notifies your system via the callback URL you provided with the payment details (value, TXID in, TXID out, etc)
- 5 - Your system confirms the payment value and grants access to the user
