runGetMethod

POSThttps://triport.io/rpc/ton

Executes a read-only smart-contract getter using TON Center v2 JSON conventions.

TON mainnetton:rpcfree+; ton_read_rpc_heavy: 15 / 20 / 100 / 250 RPS (free / basic / pro / business; default, unmeasured)

runGetMethod executes a read-only getter against a TON smart contract. The facade accepts a raw or user-friendly address, a method name or numeric method ID, and the legacy TON Center v2 stack representation.

The facade serializes the stack into the BoC form required by liteServer.runSmcMethod, then returns the VM exit code and output stack. The schema can also include the evaluated block, gas used, and last transaction ID.

Use this compatibility-oriented method for ordinary contract getters. Use runSmcMethod when the caller must explicitly control the liteserver response mode. Neither method submits a message or mutates contract state.

Parameters

JSON-RPC params is a by-name object.

Params: object (by-name).

addressstringrequired

TON contract address in raw or user-friendly form.

methodstring or integerrequired

Getter name or signed 64-bit numeric method ID.

stackarrayrequired

Legacy stack entries supplied as two-item pairs.

seqnointegeroptional

Non-negative masterchain sequence number for a historical state read.

Response

Response fields

Field	Type	Description
`jsonrpc`	string	JSON-RPC protocol version.
`id`	number or string	Correlates the response with the request.
`result`	object	Smart-contract getter result.
`result.exit_code`	integer	VM exit code returned by the liteserver.
`result.stack`	array	Getter output in the legacy stack representation.
`result.block_id`	object	Optional block at which execution was evaluated.
`result.gas_used`	integer	Optional gas-used value.
`result.last_transaction_id`	object	Optional last transaction logical time and hash.

The response is copied from the accepted live fixture. The example's exit_code is preserved exactly and is not rewritten into a success claim.

Errors

See TON errors for the shared envelope and retention handling.

Code	Meaning	When it happens
`-32602`	Invalid params	Address, method, stack, or historical sequence is missing or malformed.
`beyond_retention`	State unavailable	Contract state at the requested `seqno` is outside the selected server's window.
`-32601`	Method not found	The JSON-RPC method is outside the published read-only catalog.
`401`	Unauthorized	The API key is missing or invalid.
`429`	Rate limited	The `ton_read_rpc_heavy` budget is exceeded.

Examples

JavaScript

const params = {
  address: "EQCxE6mUtQJKFnGfaROTKOt1lZbDiiX1kCixRv7Nw2Id_sDs",
  method: "seqno",
  stack: [],
};
const response = await fetch("https://triport.io/rpc/ton", {
  method: "POST",
  headers: { "x-token": process.env.TRIPORT_API_KEY, "Content-Type": "application/json" },
  body: JSON.stringify({ jsonrpc: "2.0", id: "getter", method: "runGetMethod", params }),
});
const { result } = await response.json();

Notes

Inspect exit_code and output stack; transport success does not determine getter semantics.
Historical execution is retention-sensitive. Pruned liteservers had a floor of 86 860 000; two nodes answered from genesis, while ls-17 had a gap.
Named params and response matching by id apply to JSON-RPC batches.
sendBoc and all writes are absent. There is no REST gateway or WebSocket contract surface.
