FAQ

Questions about Crypto APIs

What is Crypto APIs?

Crypto APIs is an API provider for blockchain apps, run by Crypto APIs, Inc. (Delaware, USA) since 2018. One API key gives you blockchain data, transactions and AML screening on 35+ networks.

Is there a free trial?

Yes. Every account can start one 14-day free trial for each product. Mainnet, test networks and every feature are included, and you need no card. The trial ends after 14 days or when its credits run out, whichever comes first.

Do you hold my private keys?

No. Crypto APIs is non-custodial. You derive addresses from an xPub, we prepare unsigned transactions, you sign them on your own servers, and we broadcast them.

Which blockchains do you support?

35+ networks, including Bitcoin, Ethereum, Tron, Solana, BNB Smart Chain, Polygon, XRP Ledger and Litecoin, plus their main testnets.

How does billing work?

Each subscription is billed monthly on the 1st. If your credits run out and pay-as-you-go is on, a prepaid credit pack is added and billed to you, so your app keeps running. Pack credits are valid until the 1st.

How is NodeGrid RPC different from a node provider?

NodeGrid RPC is coming soon. NodeGrid RPC routes each call to a healthy node provider and switches automatically if it fails. You don't configure anything.
