Get Supported Contracts

Returns meta-data about the running contracts including the supported invocation types, contract invocation parameters, and contract validations. Refer to Monitoring the contract runner for details.

Request:

• requestType is getSupportedContracts
• requireBlock is the block ID of a block that must be present in the blockchain during execution (optional)
• requireLastBlock is the block ID of a block that must be last in the blockchain during execution (optional)

Response:

• hasRandomSeed (B) is true if the it has a random seed, false otherwise
• hasSecretPhrase (B) is true if the it has a secret phrase, false otherwise
• supportedContracts (A) is an array of the contracts supported by the node
• contractRunnerAccountRS (S) is the Reed-Solomon address of the account that executes the contract runner
• hasValidatorSecretPhrase (B) is true if the it has a validator secret phrase, false otherwise
• requestProcessingTime (N) is the API request processing time (in millisec)
• status (S) is current status of the contract runner
• contractRunnerAccount (N) is the number of the account that created the phasing poll
• isValidator (B) is true the contract runner is set up to be a validator, false otherwise
