REST API

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

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.

https://mainnet.mirrornode.hedera.com/api/v1/transactionsmainnet.mirrornode.hedera.com

Hedera Mirror Node Swagger UI environments

Mainnet

Testnet

Previewnet

MAINNET BASEURL https://mainnet.mirrornode.hedera.com/

TESTNET BASEURL https://testnet.mirrornode.hedera.com/

PREVIEWNET BASEURL https://previewnet.mirrornode.hedera.com/

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

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.

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.

List account entities on network

Returns a list of all account entity items on the network.

Get nfts for an account info

Returns information for all non-fungible tokens for an account.

Ordering

When considering NFTs, their order is governed by a combination of their numerical token.Id and serialnumber values, with token.id being the parent column. A serialnumbers value governs its order within the given token.id

In that regard, if a user acquired a set of NFTs in the order (2-2, 2-4 1-5, 1-1, 1-3, 3-3, 3-4), the following layouts illustrate the ordering expectations for ownership listing

1. All NFTs in ASC order: 1-1, 1-3, 1-5, 2-2, 2-4, 3-3, 3-4
2. All NFTs in DESC order: 3-4, 3-3, 2-4, 2-2, 1-5, 1-3, 1-1
3. NFTs above 1-1 in ASC order: 1-3, 1-5, 2-2, 2-4, 3-3, 3-4
4. NFTs below 3-3 in ASC order: 1-1, 1-3, 1-5, 2-2, 2-4
5. NFTs between 1-3 and 3-3 inclusive in DESC order: 3-4, 3-3, 2-4, 2-2, 1-5, 1-3

Note: The default order for this API is currently DESC

Filtering

When filtering there are some restrictions enforced to ensure correctness and scalability.

The table below defines the restrictions and support for the NFT ownership endpoint

Query Param	Comparison Operator	Support	Description	Example
token.id	eq	Y	Single occurrence only.	?token.id=X
	ne	N
	lt(e)	Y	Single occurrence only.	?token.id=lte:X
	gt(e)	Y	Single occurrence only.	?token.id=gte:X
serialnumber	eq	Y	Single occurrence only. Requires the presence of a token.id query	?serialnumber=Y

	lt(e)	Y		?spender.id=lt:Z
	gt(e)	Y		?spender.id=gt:Z

Note: When searching across a range for individual NFTs a serialnumber with an additional token.id query filter must be provided. Both filters must be a single occurrence of gt(e) or lt(e) which provide a lower and or upper boundary for search.

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.

List account balances

Returns a list of account and token balances on the network. Balance information returned by this API has a 15 minute granularity as it's generated by an asynchronous balance snapshot process. This information is limited to at most 50 token balances per account as outlined in HIP-367. As such, it's not recommended for general use and we instead recommend using either /api/v1/accounts/{id}/tokens or /api/v1/tokens/{id}/balances to obtain the current token balance information and /api/v1/accounts/{id} to return the current account balance.

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.

List transactions

Lists transactions on the network. This includes successful and unsuccessful transactions.

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
memo base64	The memo attached to the transaction encoded in Base64 format
result	Whether the cryptocurrency transaction was successful or not
entity ID	The entity ID that is created from create transactions (AccountCreateTransaction, TopicCreateTransaction, TokenCreateTransaction, ScheduleCreateTransaction, ContractCreateTransaction, FileCreateTransaction).
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.

Parameter	Description
{transaction_ID}	A specific transaction can be returned by specifying a transaction ID

Additional Examples

Example Request	Description
/api/v1/transactions/?account.id=0.0.1000	Returns transaction for account ID 1,000

List contract logs from a contract on the network

Search the logs of a specific contract across multiple contract calls. Chained logs are not included but can be found by calling /api/v1/contracts/{contractId}/results/{timestamp} or /api/v1/contracts/results/{transactionId}. When searching by topic a timestamp parameter must be supplied and span a time range of at most seven days.

Ordering

The order is governed by the combination of timestamp and index values. If the index param is omitted, the order is determined by the timestamp only.

Note: The default order for this API is currently DESC

Filtering

When filtering there are some restrictions enforced to ensure correctness and scalability.

The table below defines the restrictions and support for the endpoint

Query Param	Comparison Operator	Support	Description	Example
index	eq	Y	Single occurrence only. Requires the presence of timestamp	?index=X
	ne	N
	lt(e)	Y	Single occurrence only. Requires the presence of timestamp	?index=lte:X
	gt(e)	Y	Single occurrence only. Requires the presence of timestamp	?index=gte:X
timestamp	eq	Y	Single occurrence only.	?timestamp=Y
	ne	N
	lt(e)	Y	Single occurrence only. Optional second timestamp gt(e)	?timestamp=lte:Y
	gt(e)	Y	Single occurrence only. Optional second timestamp lt(e)	?timestamp=gte:Y

Both filters must be a single occurrence of gt(e) or lt(e) which provide a lower and or upper boundary for search.

List contracts logs across many contracts on the network

Search the logs across many contracts with multiple contract calls. Chained logs are not included but can be found by calling /api/v1/contracts/{contractId}/results/{timestamp} or /api/v1/contracts/results/{transactionId}. When searching by topic a timestamp parameter must be supplied and span a time range of at most seven days.

Ordering

The order is governed by the combination of timestamp and index values. If the index param is omitted, the order is determined by the timestamp only.

Note: The default order for this API is currently DESC

Filtering

When filtering there are some restrictions enforced to ensure correctness and scalability.

The table below defines the restrictions and support for the endpoint

Query Param	Comparison Operator	Support	Description	Example
index	eq	Y	Single occurrence only. Requires the presence of timestamp	?index=X
	ne	N
	lt(e)	Y	Single occurrence only. Requires the presence of timestamp	?index=lte:X
	gt(e)	Y	Single occurrence only. Requires the presence of timestamp	?index=gte:X
timestamp	eq	Y	Single occurrence only.	?timestamp=Y
	ne	N
	lt(e)	Y	Single occurrence only. Optional second timestamp gt(e)	?timestamp=lte:Y
	gt(e)	Y	Single occurrence only. Optional second timestamp lt(e)	?timestamp=gte:Y

Both filters must be a single occurrence of gt(e) or lt(e) which provide a lower and or upper boundary for search.

Invoke a smart contract

Returns a result from EVM execution such as cost-free execution of read-only smart contract queries, gas estimation, and transient simulation of read-write operations. If the estimate field is set to true gas estimation is executed. However, gas estimation only supports the latest block. When estimate is false, it can process calls against the earliest block and specific historical blocks when a hexadecimal or decimal block number is provided in the block field for eth_call operations. Link to Supported/Unsupported Operations Table The operations types which are not currently supported should return 501 error status.
