POSTview_code

NEAR Mainnethttps://near-mainnet.nodit.io/

Returns the contract code (WASM binary) deployed to an account, encoded in base64, together with its code hash.

Call the query method with request_type: "view_code". Querying an account with no deployed contract returns the NO_CONTRACT_CODE error, and querying an account that does not exist returns the UNKNOWN_ACCOUNT error.

near-final: a Doomslug-final block (not reverted in most cases)
final: a fully finalized block

block_idinteger

Specifies the block to query by block height (integer) or block hash (base58 string). Cannot be used together with finality.

jsonrpcstring

JSON-RPC version

idstring

Request ID

code_base64string

The entire contract WASM binary encoded in base64. The WASM can be up to about 4 MiB, and the base64 string is about 1.33 times longer. The example shows only the beginning.

hashstring

Hash of the contract code (base58). Same value as code_hash in the view_account response.

block_heightinteger

Block height.

Example: 220785385

block_hashstring

Base58-encoded 32-byte hash (block hash, chunk hash, transaction hash, etc.).

Example: 8EjuQRnAJiWkRmqxfexQFJWXXonuSMbz5AZziJLCWnWS

namestring (enum)

Error class. REQUEST_VALIDATION_ERROR (invalid request), HANDLER_ERROR (processing error), INTERNAL_ERROR (node internal error)

causeobject

The specific cause of the error.

infoobject

Additional information about the error (block hash, height, account ID, etc.)

codeinteger

Legacy JSON-RPC error code (e.g. -32000 server error, -32700 parse error, -32601 method not found)

messagestring

Legacy error message

datastring
