Responses

Successful response returning a list of blockchain transactions

Bodyapplication/json
itemsArray of objects(Transaction)required

List of blockchain transactions with their asset transfers

items[].​transaction_hashstringrequired

Hash of the transaction on the blockchain

Example: "0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef"
items[].​chain_gidstring(ChainGID)^[a-z0-9]{3,8}:[-_a-zA-Z0-9]{1,32}$required

Blockchain identifier according to CAIP-2.

The chain_gid is a case-sensitive string uniquely identifying a blockchain. It is composed of:

  • namespace — a short identifier describing an ecosystem or standard (e.g. eip155, cosmos)
  • reference — an identifier for a specific blockchain within that namespace

Syntax

chain_id = namespace ":" reference
namespace = [-a-z0-9]{3,8}
reference = [-_a-zA-Z0-9]{1,32}

Examples

  • eip155:1 — Ethereum mainnet
  • eip155:56 — Binance Smart Chain
  • cosmos:cosmoshub-4 — Cosmos Hub mainnet
  • bip122:000000000019d6689c085ae165831e93 — Bitcoin mainnet
Example: "eip155:1"
items[].​chain_familystring(ChainFamily)required

Chain family that identifies blockchain ecosystems united by common protocol or account model.

Available families:

  • evm: Ethereum Virtual Machine-based blockchains
  • bitcoin: Bitcoin and Bitcoin-compatible networks
  • solana: Solana blockchain ecosystem
  • tron: Tron blockchain ecosystem

The chain family is used to determine which blockchain ecosystem the address belongs to and how it should be generated or validated.

Enum"evm""bitcoin""solana""tron"
Example: "evm"
items[].​block_numberinteger(uint64)

Block number containing the transaction

Example: 1974382
items[].​initiatorobject(AddressRef)required

Reference to a blockchain address with minimal system context

items[].​initiator.​valuestring(AddressValue)[ 1 .. 128 ] characters^[a-zA-Z0-9]+$required

A blockchain address in its native format. This is a generic schema for any blockchain address, including addresses, smart contract addresses, and token contract addresses.

The actual format depends on the blockchain network:

  • EVM chains (Ethereum, BSC, Polygon, etc.): 0x followed by 40 hexadecimal characters

    • Example: 0x8521E8b15eCEF4D4269Fded3E6694225E096959E

  • Bitcoin: Various formats depending on address type

    • P2PKH (Legacy): Starts with 1, Example: 1GxHzNEymq1MLhxpdWAMJLN1UusYJ2Sy45
    • P2SH (Wrapped SegWit): Starts with 3, Example: 3Do92Dmff87UuY9Yiu2iFG2Kj9bpRaeJSF
    • P2WPKH (Native SegWit): Starts with bc1, Example: bc1q8faxe8g4u2v67qfwf9d8xhyl5tkkkphvet6r08

  • Solana: Base58 encoded, 32-44 characters

    • Example: 5EYCAe5ijiHbZBU14TyKHADUrkaAfc4ZyTXKRVKp49F8

  • Tron: Base58 encoded addresses starting with T

    • Example: TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t

  • Cosmos ecosystem: Bech32 format with chain-specific prefix

    • Example: cosmos1vx8knpllrj7n963p9ttd80w47kpacrhuts497x

This schema is intentionally generic to support addresses from any blockchain. The specific validation rules depend on the blockchain network and address type.

Example: "0x8521E8b15eCEF4D4269Fded3E6694225E096959E"
items[].​initiator.​is_knownbooleanrequired

items[].​transfers[].​metaEVMTransferMeta (object) or BitcoinTransferMeta (object) or SolanaTransferMeta (object) or TronTransferMeta (object)(TransferMeta)

Additional blockchain-specific metadata for the transfer. The structure varies based on the blockchain's technical requirements and available transaction data.
