0G

0G API is available on Web3 API platform (opens in a new tab).

0G Chain is a highly scalable, AI-optimized L1 blockchain designed to meet the needs of data-heavy applications. Built with a modular architecture, it allows for the independent optimization of key components like consensus, execution, and storage — making it ideal for AI-driven workflows. 0G is fully EVM-compatible, so decentralized applications (dApps) already deployed on other L1 or L2 chains (such as Ethereum or rollups) can easily leverage 0G's products without needing to migrate entirely.

0G Chain supports a data availability network, distributed storage network, and AI compute network. All of these networks integrate with 0G Chain's highly scalable consensus network, built to handle massive data volumes suitable for AI.

In order for your Web3 application to interact with 0G — either by reading blockchain data or sending transactions to the network — it must connect to an 0G node. Developers interact with the blockchain using the methods provided by the API.

We support the following networks and protocols for 0G:

      • gasPrice (string; quantity; optional): the gas price willing to be paid by the sender in wei.
      • value (string; quantity; optional): the value sent with this transaction, in wei.
      • data (string; data; optional): the hash of the method signature and encoded parameters.
    2. <string> (quantity|tag; optional): either a HEX value of a block number or one of the following block tags:

      • earliest: the lowest numbered block available on the client.
      • finalized: the most recent crypto-economically secure block; cannot be re-orged outside of manual intervention driven by community coordination.
      • safe: the most recent block that is safe from re-orgs under honest majority and certain synchronicity assumptions.
      • latest: the most recent block in the canonical chain observed by the client; this block can be re-orged out of the canonical chain even under healthy/normal conditions.
      • pending: a sample next block built by the client on top of the latest and containing the set of transactions usually taken from local mempool. In other words, it is the block that has not been mined yet.

Returns

  • <string> (quantity): the amount of gas used.

Info — node information:

Tx — transactions broadcast information:

  • broadcast_tx_sync — returns with the response from CheckTx. Does not wait for DeliverTx result.
  • broadcast_tx_async — returns right away, with no response. Does not wait for CheckTx nor DeliverTx results.
  • broadcast_tx_commit — returns with the responses from CheckTx and DeliverTx.
  • check_tx — checks the transaction without executing it.

ABCI — ABCI info:

  • abci_info — retrieves info about the application.
  • abci_query — queries the application for some information.

Information

blockchain

Retrieves block headers for minHeight <= height <= maxHeight.

At most 20 items will return for the minHeight or maxHeight parameters specified. If maxHeight does not yet exist, the blocks up to the current height will return. If minHeight does not exist (pruning), the earliest existing height will be used.

Parameters


  • minHeight (integer): the minimum block height to return.
  • maxHeight (integer): the maximum block height to return.

Returns

Block headers, in descending order (highest first).

commit

Retrieves commit results at a specified height.

Parameters


  • height (integer; default: 0): the height to return. If no height is provided, the latest block commit info is to be fetched.

Returns

Commit results. Canonical switches from false to true for block H once block H+1 has been committed, until then it's subjective and only reflects what this node has seen so far.

tx

Retrieves a transaction by hash.

Parameters


  • hash (string; required): a hash of a transaction to retrieve.
  • prove (boolean; default: false): adds proofs of the transaction's inclusion in the block.

Returns

Transaction info.

Transactions

broadcast_tx_sync

Returns with the response from CheckTx. Does not wait for DeliverTx result.

If you want to be sure that the transaction is included in a block, you can subscribe for the result using JSON-RPC via a websocket. See https://docs.cometbft.com/v0.34/core/subscription.html (opens in a new tab) If you haven't received anything after a couple of blocks, resend it. If the same happens again, send it to some other node. A few reasons why it could happen:

  1. A malicious node drops or pretends it has committed your tx.
  2. A malicious proposer (not necessary the one you're communicating with) drops transactions, which might become valid in the future (https://github.com/tendermint/tendermint/issues/3322 (opens in a new tab)).

Please refer to Tendermint docs (opens in a new tab) for formatting/encoding rules.

Parameters


  • tx (string; required): the signed transaction, encoded as Base64.

Request example

curl -X POST https://rpc.ankr.com/0g_galileo_testnet_tendermint \
-H 'Content-Type: application/json' \
-d '{
      "jsonrpc": "2.0",
      "method": "broadcast_tx_sync",
      "params": ["<BASE64_ENCODED_TRANSACTION>"],
      "id": 1
    }'

Response example

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "code": 0,
    "data": "",
    "log": "transaction successfully broadcasted",
    "hash": "0xABC123..." // The transaction hash
  }
}

broadcast_tx_async

Returns right away, with no response. Does not wait for CheckTx nor DeliverTx results.

If you want to be sure that the transaction is included in a block, you can subscribe for the result using JSON-RPC via a websocket. See https://docs.cometbft.com/v0.34/core/subscription.html (opens in a new tab) If you haven't received anything after a couple of blocks, resend it. If the same happens again, send it to some other node. A few reasons why it could happen:

  1. A malicious node drops or pretends it has committed your tx.
  2. A malicious proposer (not necessary the one you're communicating with) drops transactions, which might become valid in the future (https://github.com/tendermint/tendermint/issues/3322 (opens in a new tab)).
  3. A node is offline.

Please refer to CometBFT docs (opens in a new tab) for formatting/encoding rules.

Parameters


  • tx (string; required): the Base64-encoded signed transaction.

Request example

curl -X POST https://rpc.ankr.com/0g_galileo_testnet_tendermint \
-H 'Content-Type: application/json' \
-d '{
      "jsonrpc": "2.0",

      "params": ["<BASE64_ENCODED_TRANSACTION>"],
      "id": 1
    }'

Response example

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "code": 0,
    "data": "",
    "log": "",
    "hash": "0xABC123..." // Transaction hash
  }
}

broadcast_tx_commit

Returns with the responses from CheckTx and DeliverTx.

Use only for testing and development. In production, use BroadcastTxSync or BroadcastTxAsync. You can subscribe for the transaction result using JSON-RPC via a websocket (see CometBFT docs (opens in a new tab)).

CONTRACT: only returns error if mempool.CheckTx() errs or if we timeout waiting for tx to commit. If CheckTx or DeliverTx fails, no error will be returned, but the result will contain a non-OK ABCI code. Please refer to CometBFT docs (opens in a new tab) for formatting/encoding rules.
