description
The mirror node REST API offers the ability to query transaction information.

REST API

Hedera Mirror Nodes store the history of transactions that occurred on mainnet, testnet, and previewnet. Each transaction generates a record that is stored in a record file. The transaction contents can be accessed by the mirror node REST APIs

To make a request, use the network endpoint and the REST API of choice. For example, to get a list of transactions on mainnet you would make the following request.

{% embed url="https://mainnet.mirrornode.hedera.com/api/v1/transactions" %}

You may also check out Validation Cloud, DragonGlass, Arkhia or Ledger Works as alternatives.‌ {% endhint %}

{% hint style="warning" %} Public mainnet mirror node requests per second (RPS) are currently throttled at 50 per IP address. These configurations may change in the future depending on performance or security considerations. At this time, no authentication is required. {% endhint %}

Accounts

The accounts object represents the information associated with an account and returns a list of account information.‌

Account IDs take the following format: 0.0.<account number>.‌

Example: 0.0.1000‌

Account IDs can also take the account number as an input value. For example, for account ID 0.0.1000, the number 1000 can be specified in the request.

Balances

The balance object represents the balance of accounts on the Hedera network. You can retrieve this to view the most recent balance of all the accounts on the network at that given time. The balances object returns the account ID and the balance in hbars. Balances are checked on a periodic basis and thus return the most recent snapshot of time captured prior to the request.

Transactions

The transaction object represents the transactions processed on the Hedera network. You can retrieve this to view the transaction metadata information including transaction id, timestamp, transaction fee, transfer list, etc. If a transaction was submitted to multiple nodes, the successful transaction and duplicate transaction(s) will be returned as separate entries in the response with the same transaction ID. Duplicate transactions will still be assessed network fees.

Response Details

Response Item	Description
consensus timestamp	The consensus timestamp in seconds.nanoseconds
transaction hash	The hash value of the transaction processed on the Hedera network
valid start timestamp	The time the transaction is valid
charged tx fee	The transaction fee that was charged for that transaction
transaction id	The ID of the transaction

name	The type of transaction
max fee	The maximum transaction fee the client is willing to pay
valid duration seconds	The seconds for which a submitted transaction is to be deemed valid beyond the start time. The transaction is invalid if consensusTimestamp is greater than transactionValidStart + valid_duration_seconds.
node	The ID of the node that submitted the transaction to the network
transfers	A list of the account IDs the crypto transfer occurred between and the amount that was transferred. A negative (-) sign indicates a debit to that account. The transfer list includes the transfers between the from account and to account, the transfer of the node fee, the transfer of the network fee, and the transfer of the service fee for that transaction. If the transaction was not processed, a network fee is still assessed.
token transfers	The token ID, account, and amount that was transferred to by this account in this transaction. This will not be listed if it did not occur in the transaction
assessed custom fees	The fees that were charged for a custom fee token transfer
links.next	A hyperlink to the next page of responses

Optional Filtering

Operator	Example	Description
`lt` (less than)	`/api/v1/transactions?account.id=lt:0.0.1000`	Returns account.id transactions less than 1,000
`lte` (less than or equal to)	`/api/v1/transactions?account.id=lte:0.0.1000`	Returns account.id transactions less than or equal to 1,000
`gt` (greater than)	`/api/v1/transactions?account.id=gt:0.0.1000`	Returns account.id transactions greater than 1,000
`gte` (greater than or equal to)	`api/v1/transactions?account.id=gte:0.0.1000`	Returns account.id transactions greater than or equal to 1,000
`order` (order `asc` or `desc` values)	`/api/v1/transactions?order=asc` `/api/v1/transactions?order=desc`	Lists transactions in ascending order Lists transactions descending order

Note: It is recommended that the account.id query should not select no more than 1000 accounts in a query. If the range specified in the query results in selecting more than 1000 accounts, the API will automatically only search for the first 1000 accounts that match the query in the database and return the transactions for those. For example, if you use ?account.id=gt:0.0.15000 or if you use?account.id=gt:0.0.15000&account.id=lt:0.0.30000, then the API will only return results or some 1000 accounts in this range that match the rest of the query filters.‌

A single transaction can also be returned by specifying the transaction ID in the request. If a transaction was submitted to multiple nodes, the response will return entries for the successful transaction along with separate entries for the duplicate transaction(s). The "result" key indicates "success" for the node that processed the transaction and "DUPLICATE_TRANSACTION" for each additional node submission. Duplicate entries are still charged network fees.
