API Specification

The library allows to send and retrieve transactions/messages, get other blockchain data, and decode messages.

• Get synch information
• Get asynch information
• Send information
• Decode information

Sync get(type, input)

Performs sync request to ADAMANT blockchain endpoints.

Parameters:

• type — endpoint name
• input — filters and options for request

Supported endpoints (values of type parameters):

type	API Request	input	Result
account	/api/accounts?address= + [input]	ADAMANT address	Account's information
account_delegates	/api/accounts/delegates?address= + [input]	ADAMANT address	Votes of specific ADAMANT account — list of delegates. Returned delegates field of result.
block	/api/blocks/get?id= + [input]	Block's id	Full information about specific block
blocks	/api/blocks + [input]	Filter conditions	List of blocks filtered by input. Returned blocks field of result.
states	/api/states/get + [input]	Filter conditions	Fetch data from KVS
delegate	/api/delegates/get?username= + [input]	Delegate's name	Information for delegete by username
delegate_voters	/api/delegates/voters?publicKey= + [input]	Delegate's publicKey	List of delegete's voters
delegate_forged	/api/delegates/forging/getForgedByAccount?generatorPublicKey= + [input]	Delegate's publicKey	Forging stats of delegate
transaction	/api/transactions/get?id= + [input]	Tx ID	Transaction with specific ID
transactions	/api/transactions? + [input]	Filter conditions	List of transactions filtered by input

Examples:

const txTrx = (await api.get(`transactions`, `fromHeight=` + (Store.lastHeight - 5) + `&and:recipientId=` + Store.user.ADM.address + `&and:type=0`)).transactions;

Any other ADAMANT endpoint can be requested — set type to uri and input to full endpoint with parameters.

Example:

const txChat = (await api.get(`uri`, `chats/get/?recipientId=` + Store.user.ADM.address + `&orderBy=timestamp:desc&fromHeight=` + (Store.lastHeight - 5))).transactions;

Get information by asynchronous request

To get information from ADAMANT blockchain without maintaining the connection you need to use syncGet.js module.

Mode: asynchronous

Module format

api.syncGet(uri, isUrl, isNoJson):

• uri — endpoint or full url; mandatory
• isUrl — boolen (true/false (default)); optional. In fales case you will get url as: currentNode + uri; At true case url = uri
• isNoJson — boolen (true/false (default)); optional. In true case JSON body would be parsed

Code examples:

1. const data = await api.syncGet(config.infoservice + `/get`, true);
2. const resp = await api.syncGet(`/api/states/get?senderId=${admAddress}&key=${coin.toLowerCase()}:address`);

Send information

To send information to ADAMANT blockchain you need to use send.js module.

Mode: synchronous

Module format

api.send(passPhrase, address, payload, type = 'tokens', isEncode, amount_comment):

• passPhrase — sender's passPhrase; mandatory
• address — resipient's ADAMANT address; mandatory
• payload — sending value; optional
• type — type of payload: tokens (default) or message; optional
• isEncode — mark that payment is encoded; optional
• amount_comment — comment of payment; optional

Code examples:

1. const result = await $u[outCurrency].send({ address: senderKvsOutAddress, value: outAmount, comment: `Hey, you are lucky! Waiting for new bets!` // if ADM }); log.info(`Reward payment result: ${JSON.stringify(result, 0, 2)}.`); const { address, value, comment } = params; console.log(`Send ${value} ADM to ${address} with comment:`, comment); let res; if (comment){ res = api.send(User.passPhrase, address, comment, `message`, null, value); } else { res = api.send(User.passPhrase, address, value, null, comment); } console.log(`Send result:`, res); if (!res) { return { success: false }; } return { success: res.success, hash: res.transactionId };

2. sendAdmMsg(address, msg, type = `message`) { if (msg && !config.isDev || true) { try { let msg_markdown = msg.replace(/[^\*]\*[^\*]/g, `**`); return api.send(config.passPhrase, address, msg_markdown, type).success || false; } catch (e) { return false; } } },

Decode information

To decode information from ADAMANT blockchain transaction you can use decodeMsg.js module. Reed more about Encrypting and Decrypting Messages at this page

Mode: synchronous

Module format

api.decodeMsg(msg, senderPublicKey, passPhrase, nonce):

• msg — message you need to decrypt; mandatory
• senderPublicKey — senders' public key; mandatory
• passPhrase — private recipint's passphrase; mandatory
• nonce — nonce

Code examples:

1. const chat = tx.asset.chat; if (chat){ msg = api.decodeMsg(chat.message, tx.senderPublicKey, config.passPhrase, chat.own_message).trim(); }
