NEAR

NEAR API is available on Web3 API platform (opens in a new tab).

NEAR is a user-friendly and carbon-neutral blockchain, built from the ground up to be performant, secure, and infinitely scalable.

In technical terms, NEAR is a layer one, sharded, proof-of-stake blockchain built with usability in mind.

In order for your Web3 application to interact with NEAR — either by reading blockchain data or sending transactions to the network — it must connect to a NEAR node. Developers interact with the blockchain using the methods provided by the API.

Responses come in JSON format (opens in a new tab).

Methods supported

Access Keys — to retrieve information about an account's access keys.

View access key — retrieves information about a single access key for a given account.
View access key list — retrieves all access keys for a given account.
View access key changes (single) — retrieves individual access key changes in a specific block.
View access key changes (all) — retrieves changes to all access keys of a specific block.

Accounts/Contracts — to view details about accounts and contracts as well as perform contract calls.

View account — retrieves basic account information.
View account changes — retrieves account changes from transactions in a given account.
View contract code — retrieves the contract code (Wasm binary) deployed to the account.
View contract state — retrieves the state (key value pairs) of a contract based on the key prefix (base64 encoded).
View contract state changes — retrieves the state change details of a contract based on the key prefix (encoded to base64).
View contract code changes — retrieves code changes made when deploying a contract.
Call a contract function — calls a contract method as a view function.

Block/Chunk — to query the network and get details about specific blocks or chunks.

Block details — retrieves the block for a given height or hash.
Changes in block — retrieves the changes in a block for a given block height or hash.

Transaction status — queries status of a transaction by hash and returns the final transaction result.
Transaction status with receipts — queries status of a transaction by hash, returning the final transaction result and details of all receipts.
Receipt by ID — retrieves a receipt by its ID (as is, without a status or execution outcome).

Access Keys

The API enables you to retrieve information about an account's access keys.

View access key

Retrieves information about a single access key for a given account.

If permission of the key is FunctionCall, it will return more details such as the allowance, receiver_id, and method_names.

Parameters

id (integer; required): a request ID; unlike other networks, NEAR "dontcare" about a number you use (example: 1).
jsonrpc (string; required): a JSON RPC spec used (example: 2.0).
method (string; required): a method used for the request — query.
params (array; required):
- request_type: view_access_key
- finality (opens in a new tab)/block_id (opens in a new tab)
- account_id: "example.testnet"
- public_key: "example.testnet's public key"

Call a contract function

Calls a contract method as a view function.

Parameters

id (integer; required): a request ID; unlike other chains, NEAR "dontcare" about a number you use (example: 1).
jsonrpc (string; required): a JSON RPC spec used (example: 2.0).
method (string; required): a method used for the request — query.
params (array; required):
- request_type: call_function
- finality (opens in a new tab)/block_id (opens in a new tab)
- account_id: "example.testnet"
- method_name: name_of_a_example.testnet_method (example: view methods (opens in a new tab))
- args_base64: method_arguments_base_64_encoded

Request example (`get_num`)

curl -X POST https://rpc.ankr.com/near \
-H "content-type: application/json" \
-d '{
  "jsonrpc": "2.0",
  "id": "dontcare",
  "method": "query",

    "method_name": "get_num",
    "args_base64": "e30="
  }
}'

Request example (`get_account_staked_balance`)

The args_base64 in this example is decoded as {"account_id":"dev-1588039999690"}. The account_id would likely be the validator and not the same account for this particular view function.

  },
  "id": "dontcare"
}

Note: [48] is an array of bytes, to be specific it is an ASCII code of 0. near-sdk-rs and near-sdk-js return JSON-serialized results.
