Insight API Fields Deprecation

Insight API will deprecate all camelCase fields from responses and remove them by 30th of March 2025. Every field that was previously in camelCase has a duplicate field in snake_case for the time being, allowing users to migrate their response handling.

List of affected fields:

• decodedData
  • New name: decoded
  • Affected endpoints
    • v1/transactions (in case of decode=true query param)
    • v1/transactions/:contractAddress (in case of decode=true query param)
    • v1/transactions/:contractAddress/:signature
    • v1/events (in case of decode=true query param)
    • v1/events/:contractAddress (in case of decode=true query param)
    • v1/events/:contractAddress/:signature
• decodedData.indexedParams and decoded.indexedParams
  • New name: indexed_params
  • Affected endpoints
    • v1/events (in case of decode=true query param)
    • v1/events/:contractAddress (in case of decode=true query param)
    • v1/events/:contractAddress/:signature
• decodedData.nonIndexedParams and decoded.nonIndexedParams
  • New name: non_indexed_params
  • Affected endpoints
    • v1/events (in case of decode=true query param)
    • v1/events/:contractAddress (in case of decode=true query param)
    • v1/events/:contractAddress/:signature
• chainId
  • New name: chain_id
  • Affected endpoints
    • v1/tokens/erc20/:ownerAddress
    • v1/tokens/erc721/:ownerAddress
    • v1/tokens/erc1155/:ownerAddress
• tokenAddress
  • New name: token_address
  • Affected endpoints
    • v1/tokens/erc20/:ownerAddress
    • v1/tokens/erc721/:ownerAddress
    • v1/tokens/erc1155/:ownerAddress
• tokenId
  • New name: token_id
  • Affected endpoints
    • v1/tokens/erc721/:ownerAddress
    • v1/tokens/erc1155/:ownerAddress

Example of a decoded data response

// rest of response...

"decoded": {
    "name": "Transfer",
    "signature": "Transfer(address,address,uint256)",
    // will be deprecated
    "indexedParams": {
        "from": "0x0000000000000000000000000000000000000000",
        "to": "0x321b7ff75154472b18edb199033ff4d116f340ff"
    },
    "indexed_params": {
        "from": "0x0000000000000000000000000000000000000000",
        "to": "0x321b7ff75154472b18edb199033ff4d116f340ff"
    },
    // will be deprecated
    "nonIndexedParams": {
        "amount": 4843303142399797056
    },
    "non_indexed_params": {
        "amount": 4843303142399797056
    }
},

// rest of response...

It should be noted that the properties in indexed_params and non_indexed_params could be any format, because they are based on how the smart contract was programmed.

Example of a token response
