Blockchain Node API
This reference guide outlines the interfaces to access blockchain nodes that are created as part of the Bloq Nodes service.
Any key deviations from the standard node interface (by blockchain) are highlighted as part of the reference guide.
TIP
Testnet nodes use the same API calls as their mainnet counterparts. Just make sure the address port matches your node's chain!

BTC

TIP
The Bitcoin Node API is largely interoperable with Litecoin, with a few documented distinctions. Please see the Litecoin REST API documentation and Litecoin JSON-RPC methods for more information.

REST API

TIP
A key-client pair must be created prior to using the Nodes service. Use the bcl client-keys command if client-keys do not currently exist.
If a key-client pair already exists, use the bcl conf command to load your keypair.
TIP
In addition to having a client-key pair generated, a clientAccessToken and refreshToken are also required to access the Nodes service. Use the bcl client-token command to generate the tokens.
To learn more about the REST API that this node provides please see the REST API documentation.

JSON-RPC

The Nodes service supports the standard Bitcoin JSON-RPC calls with a number that are blacklisted. RPC calls that would negatively impact the running of the service are blacklisted. Wallet specific RPC calls are also currently not allowed as all nodes are run with --disable-wallet.
