Tron Wallet API (HTTP): 12 read methods

TRON's native wallet HTTP API on Triport: accounts, chain parameters, energy prices, contract calls without sending. Which calls map to JSON-RPC.

Send wallet requests to POST /rpc/tron/wallet/<name>. All operations require x-token: $TRIPORT_API_KEY and the tron:rpc scope. Block values are decimal JSON integers. Addresses default to hex-41; Base58 requires visible: true. This is a read-only API: no broadcasttransaction and no /walletsolidity. getaccountresource and estimateenergy are not served. The keyless https://triport.io/public/tron URL exposes JSON-RPC reads, not wallet methods.

Wallet method or JSON-RPC?

Choose the native response when you need TRON-specific fields. An EVM call can answer a narrower question without returning the entire native object.

Read task	Wallet HTTP method	JSON-RPC counterpart	Configured category
Native account details or only its TRX balance	`getaccount`	`eth_getBalance` for balance only	`tron_read_rpc`
Current block in native or EVM form	`getnowblock`	`eth_getBlockByNumber` with `latest`	`tron_read_rpc`
Block at a selected height	`getblockbynum`	`eth_getBlockByNumber`	Wallet: `tron_read_rpc_heavy`; JSON-RPC: `tron_read_rpc`
Contract result, with energy information on the native surface	`triggerconstantcontract`	`eth_call` for return bytes only	Wallet: `tron_read_rpc_heavy`; JSON-RPC: `tron_read_rpc`
Energy burn price among the current network parameters	`getchainparameters`	`eth_gasPrice` for one price	`tron_read_rpc`
Historical energy-price changes or only the current price	`getenergyprices`	`eth_gasPrice` has no price history	`tron_read_rpc`

The surfaces differ in encoding and response fields; these pairs are task alternatives, not interchangeable wire formats. Limits are configured and unmeasured; see TRON limits. For connection values and plans, see the Tron RPC node endpoint.

Confirmed execution

Method	Category	Summary	Tier / rate limit
`gettransactioninfobyid`	`tron_read_rpc`	Return confirmed transaction execution information.	free+; 15 / 20 / 100 / 250 RPS sustained · short burst 30 / 40 / 200 / 500 (default, unmeasured)

Network constraints

No public wallet mempool, pending queue, or WebSocket surface is published.
Historical block depth varies; an old block does not establish historical state coverage.
The OpenAPI response schema is extensible. Dated observations on method pages describe observed fields rather than a closed response schema.
Remaining energy and bandwidth require getaccountresource, which is not served. Account state from getaccount is not a substitute for that budget.
Included transaction information is not a solidified-state confirmation; /walletsolidity is not served.

For simulation, burn prices and resource caveats, follow estimate a USDT transfer fee and TRON energy vs bandwidth.
