Get the health of the service

Lists the supported EVM-compatible chains. Filterable by network.

List chains

Gets chain information for the EVM-compatible chain if supported by the api.

Get chain information

Lists the latest indexed blocks on the EVM-compatible chain sorted in descending order by block timestamp.

List latest blocks

Gets the details of an individual block on the EVM-compatible chain.

Get block

If the address is a smart contract, returns the transaction in which it was deployed.

Get deployment transaction

Lists all contracts deployed by the given address.

List deployed contracts

Lists ERC transfers for an ERC-20, ERC-721, or ERC-1155 contract address.

List ERC transfers

Returns a list of transactions where the given wallet address had an on-chain interaction for the given chain. The ERC-20 transfers, ERC-721 transfers, ERC-1155, and internal transactions returned are only those where the input address had an interaction. Specifically, those lists only inlcude entries where the input address was the sender (`from` field) or the receiver (`to` field) for the sub-transaction. Therefore the transactions returned from this list may not be complete representations of the on-chain data. For a complete view of a transaction use the `/chains/:chainId/transactions/:txHash` endpoint.

Filterable by block ranges.

List transactions

Lists native transactions for an address. Filterable by block range.

List native transactions

Lists ERC-20 transfers for an address. Filterable by block range.

List ERC-20 transfers

Lists ERC-721 transfers for an address. Filterable by block range.

List ERC-721 transfers

Lists ERC-1155 transfers for an address. Filterable by block range.

List ERC-1155 transfers

Returns a list of internal transactions for an address and chain. Filterable by block range.

Note that the internal transactions list only contains `CALL` or `CALLCODE` transactions with a non-zero value and `CREATE`/`CREATE2` transactions. To get a complete list of internal transactions use the `debug_` prefixed RPC methods on an archive node.

List internal transactions

Gets the details of a single transaction.

Get transaction

Lists the transactions that occured in a given block.

List transactions for a block

Lists the latest transactions. Filterable by status.

List latest transactions

Gets native token balance of a wallet address.

Balance at a given block can be retrieved with the `blockNumber` parameter.

Get native token balance

Lists ERC-20 token balances of a wallet address.

Balance at a given block can be retrieved with the `blockNumber` parameter.

Balance for specific contracts can be retrieved with the `contractAddresses` parameter.

List ERC-20 balances

Lists ERC-721 token balances of a wallet address.

Balance for a specific contract can be retrieved with the `contractAddress` parameter.

List ERC-721 balances

Lists ERC-1155 token balances of a wallet address.

Balance at a given block can be retrieved with the `blockNumber` parameter.

Balance for a specific contract can be retrieved with the `contractAddress` parameter.

List ERC-1155 balances

Lists ERC-721 and ERC-1155 token balances of a wallet address.

Balance for a specific contract can be retrieved with the `contractAddress` parameter.

List collectible (ERC-721/ERC-1155) balances

Gets metadata about the contract at the given address.

Get contract metadata

Triggers reindexing of token metadata for an NFT token. Reindexing can only be called once per hour for each NFT token.

Reindex NFT metadata

List tokens

Gets token details for a specific token of an NFT contract.

Get token details

Returns Primary Network chains that each address has touched in the form of an address mapped array. If an address has had any on-chain interaction for a chain, that chain's chain id will be returned.

Get chain interactions for addresses

Gets network details such as validator and delegator stats.

Get network details

Lists all blockchains registered on the network.

List blockchains

Lists all subnets registered on the network.

List subnets

Get details of the Subnet registered on the network.

Get Subnet details by ID

Lists details for validators. By default, returns details for all validators. Filterable by validator node ids and minimum delegation capacity.

List validators

List validator details for a single validator.  Filterable by validation status.

Get single validator details

List delegators

Gets a block by block height or block hash on one of the Primary Network chains.

Lists the latest blocks proposed by a given NodeID on one of the Primary Network chains.

List blocks proposed by node

Lists latest blocks on one of the Primary Network chains.

List vertices

Get vertex

Lists vertices at the given vertex height on the X-Chain.

List vertices by height

Gets the details of a single transaction on one of the Primary Network chains.

Lists the latest transactions on one of the Primary Network chains.

Transactions are filterable by addresses, txTypes, and timestamps. When querying for latest transactions without an address parameter, filtering by txTypes and timestamps is not supported. An address filter must be provided to utilize txTypes and timestamp filters.

Given that each transaction may return a large number of UTXO objects, bounded only by the maximum transaction size, the query may return less transactions than the provided page size. The result will contain less results than the page size if the number of utxos contained in the resulting transactions reach a performance threshold.

Lists active staking transactions on the P-Chain for the supplied addresses.

List staking transactions

Lists asset transactions corresponding to the given asset id on the X-Chain.

List asset transactions

Gets primary network balances for one of the Primary Network chains for the supplied addresses.

C-Chain balances returned are only the shared atomic memory balance. For EVM balance, use the `/v1/chains/:chainId/addresses/:addressId/balances:getNative` endpoint.

Get balances

Lists UTXOs on one of the Primary Network chains for the supplied addresses.

List UTXOs

Lists pending rewards on the Primary Network for the supplied addresses.

List pending rewards

Lists historical rewards on the Primary Network for the supplied addresses.

List historical rewards

Gets asset details corresponding to the given asset id on the X-Chain.

Get asset details

Get a teleporter message

Lists teleporter messages. Ordered by timestamp in descending order.

List teleporter messages

Lists teleporter messages by address. Ordered by timestamp in descending order.

List teleporter messages by address

Gets operation details for the given operation id.

Get operation

Trigger a transaction export operation with given parameters.

The transaction export operation runs asynchronously in the background. The status of the job can be retrieved from the `/v1/operations/:operationId` endpoint using the `operationId` returned from this endpoint.
