# HTTP ### Give it a go! If your blockchain has just been deployed, it will initially contain only the **genesis account**. You can verify this account using the HTTP interface. For example, on a local setup on port **36002**, use the following endpoint: ```http http://127.0.0.1:36002/v1/account/getGenesisAccount ``` This will return details of the genesis account, including address, balance, and other initial parameters. ```http HTTP GET https://{endpoint}/getGenesisAccount or curl get https://{endpoint}/getGenesisAccount ``` If you would like to use our testnet or mainnet as reference, the respective endpoints are below: Testnet: Mainnet: The response content should be as follows: ```json { "error_code" : 0, "result" : { "address" : "ztxSn8xpL7c2xkxwbreVCs6EZ7KZbBvtDaLtV", "assets" : null, "balance" : 100000000000000000, "metadatas" : null, "priv" : { "master_weight" : 1, "thresholds" : { "tx_threshold" : 1 } } } } ``` The value of `address` in the returned result is the genesis account address. ### HTTP Interfaces #### Generating Public and Private Key pairs - Test ```http HTTP GET /createKeyPair ``` * CURL command ```shell curl get https://{endpoint}/createKeyPair ``` * Function > **Note:** This interface is intended **only for testing purposes** and should **not be used in a production environment**. In production, use the SDK or command line tools. Calling this interface on an untrusted or malicious node server may expose your **private key**, as it only generates a key pair and does **not broadcast anything to the blockchain**. Use it with caution and only in isolated, secure testing environments. * Return value ```json { "error_code" : 0, "result" : { "address" : "ztxSkMvC2RcvXLpDgXBJCSb4m9mPe8gpNDKAG", //The account address "private_key" : "privbzMRMFKoT8xPSPLqXoJb3GxgoULcR2go9WVNPG2N9e9oX251AgAU", //The private key of the account "private_key_aes" : "7594a97bc5e6432704cc5f58ff60727ee9bda10a6117915d025553afec7f81527cb857b882b7c775391fe1fe3f7f3ec198ea69ada138b19cbe169a1a3fa2dec8", //The data after the private key of the account is encrypted with AES "public_key" : "b00101da11713eaad86ad8ededfc28e86b8cd619ca2d593a21d8b82da34320a7e63b09c279bc", //The public key of the account "public_key_raw" : "01da11713eaad86ad8ededfc28e86b8cd619ca2d593a21d8b82da34320a7e63b", //The data of the public key excluding the prefix and suffix "sign_type" : "ed25519" //The type of the account encryption } } ``` #### getAccount ```http HTTP GET /getAccount?address=ztxSn8xpL7c2xkxwbreVCs6EZ7KZbBvtDaLtV&key=hello&code=xxx&issuer=xxx ``` * CURL command ```shell curl get https://{endpoint}/getGenesisAccount?address=ztxSn8xpL7c2xkxwbreVCs6EZ7KZbBvtDaLtV ``` * Function Return information about the specified account and all its assets and metadata. * Parameters | Parameter | Description | | ---------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | address (required) | Zetrix account address. | | key (optional) | Specifies the key to retrieve a specific metadata value associated with the account.

This allows you to assign signer weights and operation thresholds. ```json { "master_weight": "70",//The weight for the private key of this address is 70 "signers": [//The weights assigned { "address": "ztxSigpdiWcW22hw54i9PEFk1s4WLEy5Rmh6K", "weight": 55 //The weight of the above address is 55 }, { "address": "ztxSX1SypC33doY4a5MYYr5zBZUvB33kKHdAo", "weight": 100 //The weight of the above address is 100 } ], "tx_threshold": "8",//The weight required to initiate the transaction is 8 "type_thresholds": [ { "type": 1,//The weight required to create an account is 11 "threshold": 11 }, {//The weight required to issue an asset is 21 "type": 2, "threshold": 21 }, {//The weight required to transfer assets is 31 "type": 3, "threshold": 31 }, {//The weight required to set metadata is 41 "type": 4, "threshold": 41 }, {//The weight required to change controllers is 51 "type": 5, "threshold": 51 }, {//The weight required to change operations is 61 "type": 6, "threshold": 61 } ] } ``` ### Example In this example, the account **`ztxSW512jUyDASna878ECgZ4QFyhh6AtEJP6E`** initiates a transaction containing a single operation: * **Create a new account** with address **`ztxSX1SypC33doY4a5MYYr5zBZUvB33kKHdAo`** * The account creation is completed by **transferring Gas** to the new account during the operation. #### Assembling Transactions Referring to the structure of Transaction Structure, the following three steps are required: 1. Obtaining the account nonce value 2. Assembling operations 3. Generating transaction objects **Obtaining the Account Nonce Value** In a transaction structure, it's essential to confirm the **serial number (`nonce`)** of the initiating account. To do this: 1. Use the **`getAccountBase`** interface to retrieve the current `nonce` value of the initiating account. 2. **Increment the `nonce` by 1** to set the correct value for the new transaction. This ensures transaction ordering and prevents replay. The interface call is as follows: ```http HTTP GET https://{endpoint}/getAccountBase?address=ztxSW512jUyDASna878ECgZ4QFyhh6AtEJP6E or curl get https://{endpoint}/getAccountBase?address=ztxSW512jUyDASna878ECgZ4QFyhh6AtEJP6E ``` The following content is returned: ```json { "error_code" : 0, "result" : { "address" : "ztxSW512jUyDASna878ECgZ4QFyhh6AtEJP6E", "assets_hash" : "ad67d57ae19de8068dbcd47282146bd553fe9f684c57c8c114453863ee41abc3", "balance" : 96545066100, "metadatas_hash" : "ad67d57ae19de8068dbcd47282146bd553fe9f684c57c8c114453863ee41abc3", "nonce" : 20, "priv" : { "master_weight" : 1, "thresholds" : { "tx_threshold" : 1 } } } } ``` **Assembling Operations** According to the structure of Operations Structure, Operation Codes, and Transferring Gas Assets structure, the JSON format of the generation operation is as follows: ```json { "type": 7, "pay_coin": { "dest_address": "ztxSX1SypC33doY4a5MYYr5zBZUvB33kKHdAo", "amount": 10000000, "input": "" } } ``` **Generating Transaction Objects** In this example, after obtaining the account's nonce value of **20**, the **new transaction’s serial number** is set to **21**. Based on the assembled operation structure, the transaction JSON format will look like this: ```json { "source_address": "ztxSW512jUyDASna878ECgZ4QFyhh6AtEJP6E", "nonce": 21, "fee_limit":1000000, "gas_price":1000, "operations": [{ "type": 7, "pay_coin": { "dest_address": "ztxSX1SypC33doY4a5MYYr5zBZUvB33kKHdAo", "amount": 10000000, "input": "" } }] } ``` #### Serializing Transaction Data This is done through the `getTransactionBlob` interface. The interface call is as follows: ```http HTTP POST https://{endpoint}/getTransactionBlob or curl https://{endpoint}/getTransactionBlob -X POST -d "{\"source_address\":\"ztxSW512jUyDASna878ECgZ4QFyhh6AtEJP6E\",\"nonce\":21,\"fee_limit\":1000000,\"gas_price\":1000,\"operations\":[{\"type\":7,\"pay_coin\":{\"dest_address\":\"ztxSX1SypC33doY4a5MYYr5zBZUvB33kKHdAo\",\"amount\":10000000,\"input\":\"\"}}]}" ``` Return the following content: ```json { "error_code": 0, "error_desc": "", "result": { "hash": "3f90865062d7737904ea929cbde7c45e831e4972cf582b69a0198781c452e9e1", "transaction_blob": "0a246275516f50326552796d4163556d33757657675138526e6a7472536e58425866417a7356101518c0843d20e8073a2f0807522b0a24627551747336446654354b6176745639344a675a79373548397069776d62374b6f5557671080ade204" } } ``` #### #### Signing Signatures Signing signatures is to sign the value of `transaction_blob` in `getTransactionBlob` with the private key of `ztxSW512jUyDASna878ECgZ4QFyhh6AtEJP6E` and generate a public key. For details, please refer to keypair. The resulting signature data is as follows: ```json ［{ "sign_data": "ACF64A7D41244AFC4465DBC225D616E0499776140D46BA7A84B1B6B263DAF1422904137E0181301F480F7114EC7CC5BBE4763EDA981E565EF81EF7705596CB0B", "public_key": "b00168eceea7900ddcb8f694161755f98590ba7944de3bfe339610fe0cacc10a18372dcbf71b" }］ ``` #### Submitting Transaction Data According to the signature data obtained by Signing Signatures and the `transaction_blob` obtained by Serializing Transaction Data, the JSON format of the body in the `submitTransaction` interface is generated as follows: ```json { "items" : [{ "transaction_blob" : "0a246275516f50326552796d4163556d33757657675138526e6a7472536e58425866417a7356101518c0843d20e8073a2f0807522b0a24627551747336446654354b6176745639344a675a79373548397069776d62374b6f5557671080ade204", "signatures" : [{ "sign_data" : "ACF64A7D41244AFC4465DBC225D616E0499776140D46BA7A84B1B6B263DAF1422904137E0181301F480F7114EC7CC5BBE4763EDA981E565EF81EF7705596CB0B", "public_key" : "b00168eceea7900ddcb8f694161755f98590ba7944de3bfe339610fe0cacc10a18372dcbf71b" }] }] } ``` The interface call is as follows: ```http HTTP POST https://{endpoint}/submitTransaction or curl https://{endpoint}/submitTransaction -X POST -d "{\"items\":[{\"transaction_blob\":\"0a246275516f50326552796d4163556d33757657675138526e6a7472536e58425866417a7356101518c0843d20e8073a2f0807522b0a24627551747336446654354b6176745639344a675a79373548397069776d62374b6f5557671080ade204\",\"signatures\":[{\"sign_data\":\"ACF64A7D41244AFC4465DBC225D616E0499776140D46BA7A84B1B6B263DAF1422904137E0181301F480F7114EC7CC5BBE4763EDA981E565EF81EF7705596CB0B\",\"public_key\":\"b00168eceea7900ddcb8f694161755f98590ba7944de3bfe339610fe0cacc10a18372dcbf71b\"}]}]}" ``` Return the following content: ```json { "results": [ { "error_code": 0, "error_desc": "", "hash": "3f90865062d7737904ea929cbde7c45e831e4972cf582b69a0198781c452e9e1" } ], "success_count": 1 } ``` #### Querying the Transaction Result According to the hash obtained by the `submitTransaction` interface, confirm whether the transaction is executed successfully by the `getTransactionHistory` interface (check whether `error_code` under `transactions` is equal to 0). The interface call is as follows: ```http HTTP GET https://{endpoint}/getTransactionHistory?hash=3f90865062d7737904ea929cbde7c45e831e4972cf582b69a0198781c452e9e1 or curl get https://{endpoint}/getTransactionHistory?hash=3f90865062d7737904ea929cbde7c45e831e4972cf582b69a0198781c452e9e1 ``` Return the following result: ```json { "error_code": 0,//The transaction is queried "result": { "total_count": 1, "transactions": [ { "actual_fee": 245000, "close_time": 1552125554325904, "error_code": 0,//The transaction is executed successfully "error_desc": "", "hash": "3f90865062d7737904ea929cbde7c45e831e4972cf582b69a0198781c452e9e1", "ledger_seq": 2688046, "signatures": [ { "public_key": "b00168eceea7900ddcb8f694161755f98590ba7944de3bfe339610fe0cacc10a18372dcbf71b", "sign_data": "acf64a7d41244afc4465dbc225d616e0499776140d46ba7a84b1b6b263daf1422904137e0181301f480f7114ec7cc5bbe4763eda981e565ef81ef7705596cb0b" } ], "transaction": { "fee_limit": 1000000, "gas_price": 1000, "nonce": 21, "operations": [ { "pay_coin": { "amount": 10000000, "dest_address": "ztxSX1SypC33doY4a5MYYr5zBZUvB33kKHdAo" }, "type": 7 } ], "source_address": "ztxSW512jUyDASna878ECgZ4QFyhh6AtEJP6E" }, "tx_size": 245 } ] } } ``` ### Error Codes The error code is composed of two parts: * error\_code : Error code, approximate error classification * error\_desc : Error Description, which can accurately find the error specific information from the error description The error list is as follows:
