HTTP API

This article introduces FullNode's HTTP APIs and their usage.

Note

Although TRON has avoided XSS by setting the Content-Type of HTTP APIs to application/json, there are a few APIs that don't have input validation. To better protect user data security, we recommend that you correctly encode any data from APIs before using it in any UI, especially when the parameter visible equals true.

Here is a typical XSS protection method: Encode all data from the APIs in HTML. Use methods such as encodeURIComponent() or escape() to encode the data, which can convert special characters into their HTML entities and prevent them from being interpreted as HTML code by the browser.

Please ensure that XSS protection is implemented for all data from the APIs to maintain the security of user data. We understand that you may need more information about XSS protection. It is recommended that you refer to the following resources: OWASP XSS Prevention Cheat Sheet.

The TRON node's HTTP API supports two address formats. Developers can use the visible parameter to control the address format in both requests and responses.

The rules for the visible parameter are as follows:

  • "visible": false (default)： Addresses in parameters and return values must be in HexString format. If this parameter is omitted, the default value is used.
  • "visible": true：Addresses in parameters and return values must be in Base58Check format.

How to Set:：

  1. For GET requests or queries without parameters Append visible=true as a URL query parameter. 

    http://127.0.0.1:8090/wallet/listexchanges?visible=true

  2. For POST requests Add "visible": true to the JSON request body. 

    curl -X POST http://127.0.0.1:8090/wallet/createtransaction -d
'{
    "owner_address": "TRGhNNfnmgLegT4zHNjEqDSADjgmnHvubJ",
    "to_address": "TJCnKsPa7y5okkXvQAidZBzqx3QyQ6sxMW",
    "amount": 1000000,
    "visible": true
}'

Fullnode HTTP API

The Fullnode HTTP API is categorized as follows:

Accounts

The following are the APIs related to on-chain accounts:

wallet/validateaddress

Description: Validates if a TRON address is effective. This is useful for pre-checking user-inputted addresses in applications before sending a transaction.

curl -X POST  http://127.0.0.1:8090/wallet/validateaddress -d '{"address": "4189139CB1387AF85E3D24E212A008AC974967E561"}'

Parameters: * address:can be in Base58Checksum, hexString, or base64 format.

Return Value: Indicates whether the address is valid or invalid. Example: 

# Success Example

}

# Error Example
{
    "result": false,
    "message": "Invalid address"

Parameter:

  • A complete signed transaction object. This is created by adding a signature field to the unsigned transaction returned by a creation API (e.g., wallet/createtransaction).

Return Value: * A JSON object with the broadcast result. * A successful response typically includes "result": true, indicating the node has received the transaction and started broadcasting it.

Important Note: "result": true does not mean the transaction has been confirmed on the blockchain. It only means "successfully broadcast." You must use the txID with the wallet/gettransactioninfobyid or wallet/gettransactionbyid endpoints to check the final on-chain status.

wallet/broadcasthex

Description: Broadcasts a transaction that has been signed and serialized into a hexadecimal string. 

curl -X POST  http://127.0.0.1:8090/wallet/broadcasthex -d '{"transaction":"0A8A010A0202DB2208C89D4811359A28004098A4E0A6B52D5A730802126F0A32747970652E676F6F676C65617069732E636F6D2F70726F746F636F6C2E5472616E736665724173736574436F6E747261637412390A07313030303030311215415A523B449890854C8FC460AB602DF9F31FE4293F1A15416B0580DA195542DDABE288FEC436C7D5AF769D24206412418BF3F2E492ED443607910EA9EF0A7EF79728DAAAAC0EE2BA6CB87DA38366DF9AC4ADE54B2912C1DEB0EE6666B86A07A6C7DF68F1F9DA171EEE6A370B3CA9CBBB00"}'
Parameters:

  • transaction: A complete transaction, including all data and signatures, serialized into a single hex string.

Return Value:

  • A JSON object with the broadcast result.
  • A successful response typically includes "result": true, indicating the node has received the transaction and started broadcasting it.

Important Note: "result": true does not mean the transaction has been confirmed on the blockchain. It only means "successfully broadcast." You must use the txID with the wallet/gettransactioninfobyid or wallet/gettransactionbyid endpoints to check the final on-chain status.

wallet/getsignweight

Description: Checks the current signature status of a transaction requiring Account Management Permission. This is a key pre-broadcast check in the workflow for an Account Management Permission to see if the collected signature weight has met the required threshold.

In a scenario involving an Account Management Permission, a transaction may require multiple private key signatures. This API is used to check whether the currently collected signature weight has reached the set threshold before all signatures are collected. It is a key pre-broadcast check tool in the signing process for an Account Management Permission.
