Blockchain API
Mainnet + Testnet
Zcash API
The Crypto APIs Zcash API, part of the Blockchain API, lets you read balances, transactions, blocks and unspent outputs and send ZEC without running a node. One API key covers mainnet and testnet. Webhooks tell your server when a payment confirms, and we never hold your private keys.
What can you do with the Zcash API?
Read balances and history
Confirmed balance, transactions and unspent outputs (UTXOs) for any Zcash address.
Work with xPubs
Derive addresses and sync balances from an extended public key (xPub).
Estimate fees
Fee recommendations for slow, standard and fast confirmation on Zcash.
Prepare and broadcast
We build the unsigned transaction. You sign it, and we send it to the network.
Get webhooks
We call your URL when coins arrive at an address and when the transaction confirms.
Same shape on 35+ networks
Swap zcash for another chain in the path, such as Bitcoin or Dash.
How do I get the latest Zcash block?
Send one GET request with your API key; the same request works on testnet when you replace mainnet with testnet in the path.

- JSON responses, same shape on every chain

Which Zcash endpoints are available?
The main calls. Every path takes the network: mainnet or testnet.
/addresses-historical/utxo/zcash/mainnet/{address}/unspent-outputs/blockchain-events/zcash/mainnet/address-coins-transactions-confirmedHow do I send a Zcash transaction without giving up my keys?
Crypto APIs never holds your private keys. You keep signing; we do the rest.
- Step 1 Derive Get Zcash addresses from your xPub.
- Step 2 Prepare We build the unsigned transaction with the fee set.
- Step 3 Sign locally You sign on your own servers. Keys never leave.
- Step 4 Broadcast We push the signed transaction to the Zcash network.
- Step 5 Confirm A webhook tells you when it confirms.
Zcash API vs Zcash RPC: which do I need?
Most apps start with the API. Use RPC when you need a method the node exposes directly.
Zcash RPC
Need raw node calls (JSON-RPC)? NodeGrid RPC will give you one endpoint with automatic failover between partner providers. Until then, JSON-RPC access is part of the Blockchain API.

Coming soonPrivacy-protecting digital currency
Zcash was built on the original Bitcoin code base to provide a secure means of buying goods and services and exchanging currencies, including crypto and fiat.
Zcash provides users with the strongest privacy available for any digital currency. It uses shielded transactions, ensuring transactions remain completely private and confidential while allowing people to transact efficiently and safely with low fees.

Zcash API questions
Is there a free Zcash API?
You can try it free for 14 days. The Blockchain API free trial covers Zcash and every feature, with no card. It ends after 14 days or when its credits run out; after that, calls need a subscription, listed on the pricing page.
How do I get the balance of a Zcash address?
Call the address balance endpoint with the address; it returns the confirmed balance in ZEC. For the spendable coins, list the address's unspent outputs (UTXOs).
How do I broadcast a Zcash transaction?
Sign the transaction on your own server, then send the signed raw transaction to the broadcast endpoint, authenticated with your API key, and Crypto APIs pushes it to the Zcash network and returns the transaction ID. We can prepare the unsigned transaction for you first.
Do you support Zcash testnet?
Yes. Every Zcash endpoint works on mainnet and testnet. Change mainnet to testnet in the path; the same API key works on both.
What makes Zcash different to work with?
It is a UTXO chain — balances are the sum of unspent outputs, not a single account figure. Because there is no account balance to read, spending means selecting unspent outputs and handling change. Crypto APIs does that selection for you in prepare-transactions, so you sign one prepared transaction rather than assembling inputs yourself.
How do I know when a Zcash transaction is confirmed?
Create a webhook subscription for the address. Crypto APIs calls your URL when a transaction to or from it confirms on Zcash.
