JSON-RPC API

Omni Core is a fork of Bitcoin Core, with Omni Protocol feature support added as a new layer of functionality on top. As such interacting with the API is done in the same manner (JSON-RPC) as Bitcoin Core, simply with additional RPCs available for utilizing Omni Protocol features.

As all existing Bitcoin Core functionality is inherent to Omni Core, the RPC port by default remains as 8332 as per Bitcoin Core. If you wish to run Omni Core in tandem with Bitcoin Core (eg. via a separate datadir) you may utilize the -rpcport<port> option to nominate an alternative port number.

All available commands can be listed with "help", and information about a specific command can be retrieved with "help <command>".

Please note: this document may not always be up-to-date. There may be errors, omissions or inaccuracies present.

Raw transactions

The RPCs for raw transactions/payloads can be used to decode or create raw Omni transactions.

Raw transactions need to be signed with "signrawtransaction" and then broadcasted with "sendrawtransaction".

$ omnicore-cli "omni_createpayload_enablefreezing" 3

omni_createpayload_disablefreezing

Creates the payload to disable address freezing for a centrally managed property.

IMPORTANT NOTE: Disabling freezing for a property will UNFREEZE all frozen addresses for that property!

Arguments:

Name Type Presence Description
propertyid number required the identifier of the tokens

Result:

"payload"  // (string) the hex-encoded payload

Example:

$ omnicore-cli "omni_createpayload_disablefreezing" 3

omni_createpayload_freeze

Creates the payload to freeze an address for a centrally managed token.

Note: if the server is not synchronized, amounts are considered as divisible, even if the token may have indivisible units!

Arguments:

Name Type Presence Description
toaddress string required the address to freeze tokens for
propertyid number required the property to freeze tokens for (must be managed type and have freezing option enabled)
amount string required the amount of tokens to freeze (note: this is unused - once frozen an address cannot send any transactions)

Result:

"payload"  // (string) the hex-encoded payload

Example:

$ omnicore-cli "omni_createpayload_freeze" "3HTHRxu3aSDV4deakjC7VmsiUp7c6dfbvs" 31 "100"

omni_createpayload_unfreeze

Creates the payload to unfreeze an address for a centrally managed token.

Note: if the server is not synchronized, amounts are considered as divisible, even if the token may have indivisible units!

Arguments:

Name Type Presence Description
toaddress string required the address to unfreeze tokens for
propertyid number required the property to unfreeze tokens for (must be managed type and have freezing option enabled)
amount string required the amount of tokens to unfreeze (note: this is unused)

Result:

"payload"  // (string) the hex-encoded payload

Example:

$ omnicore-cli "omni_createpayload_unfreeze" "3HTHRxu3aSDV4deakjC7VmsiUp7c6dfbvs" 31 "100"

Fee system

The RPCs for the fee system can be used to obtain data about the fee system and fee distributions.

omni_getfeecache

Obtains the current amount of fees cached (pending distribution).

If a property ID is supplied the results will be filtered to show this property ID only. If no property ID is supplied the results will contain all properties that currently have fees cached pending distribution.

Arguments:

Name Type Presence Description
propertyid number optional the identifier of the property to filter results on

Result:

[                                  // (array of JSON objects)
  {
    "propertyid" : nnnnnnn,        // (number) the property id
    "cachedfees" : "n.nnnnnnnn",   // (string) the amount of fees cached for this property
  },
...
]

Example:

$ omnicore-cli "omni_getfeecache" 31

omni_getfeetrigger

Obtains the amount at which cached fees will be distributed.

If a property ID is supplied the results will be filtered to show this property ID only. If no property ID is supplied the results will contain all properties.

Arguments:

Name Type Presence Description
propertyid number optional the identifier of the property to filter results on

Result:

[                                  // (array of JSON objects)
  {
    "propertyid" : nnnnnnn,        // (number) the property id
    "feetrigger" : "n.nnnnnnnn",   // (string) the amount of fees required to trigger distribution
  },
...
]

Example:

$ omnicore-cli "omni_getfeetrigger" 31

omni_getfeeshare

Obtains the current percentage share of fees addresses would receive if a distribution were to occur.

If an address is supplied the results will be filtered to show this address only. If no address is supplied the results will be filtered to show wallet addresses only. If a wildcard is provided ("*") the results will contain all addresses that would receive a share.

If an ecosystem is supplied the results will reflect the fee share for that ecosystem (main or test). If no ecosystem is supplied the results will reflect the main ecosystem.

Arguments:

Name Type Presence Description
address string optional the address to filter results on
ecosystem number optional the ecosystem to obtain the current percentage fee share (1 = main, 2 = test)

Result:

[                                  // (array of JSON objects)
  {
    "address" : "address"          // (string) the adress that would receive a share of fees
    "feeshare" : "n.nnnn%",        // (string) the percentage of fees this address will receive based on the current state
  },
...
]

Example:

$ omnicore-cli "omni_getfeeshare" "1CE8bBr1dYZRMnpmyYsFEoexa1YoPz2mfB" 1

omni_getfeedistribution

Obtains data for a past distribution of fees.

A distribution ID must be supplied to identify the distribution to obtain data for.

Arguments:

Name Type Presence Description
distributionid number required the identifier of the distribution to obtain data for

Result:

{
  "distributionid" : n,            // (number) the distribution id
  "propertyid" : n,                // (number) the property id of the distributed tokens
  "block" : n,                     // (number) the block the distribution occurred
  "amount" : "n.nnnnnnnn",         // (string) the amount that was distributed
  "recipients": [                  // (array of JSON objects) a list of recipients
    {
      "address" : "address",       // (string) the address of the recipient

Depreciated API calls

To ensure backwards compatibility, depreciated RPCs are kept for at least one major version.

The following calls are replaced in Omni Core 0.0.10, and queries with the old command are forwarded.
