# 0G

<figure><img src="/files/NaGLj3Pt6JZjeMukVaeo" alt=""><figcaption></figcaption></figure>

> 0G API is available on [Web3 API platform](https://crypto-chief.com/rpc/og/).

*0G* (Zero Gravity) is a modular Layer 1 blockchain purpose-built for data-intensive AI applications. Its architecture separates consensus, execution, and storage into independently scalable components. The 0G ecosystem spans three networks: a data availability network, a decentralized storage network, and an AI compute network — all unified under a shared high-throughput consensus layer engineered for the data volumes demanded by AI workloads. 0G is EVM-compatible, allowing existing dApps to leverage 0G infrastructure without a full migration.

0G exposes three interfaces: an EVM-compatible [JSON-RPC](https://www.jsonrpc.org/specification) API, a Tendermint JSON-RPC/REST API for consensus-layer queries, and a Beaconkit REST API.

### `eth_getTransactionCount`

> Returns the nonce (number of transactions sent) for the specified address.

#### Parameters

* `id` (integer; required): a request ID (example: 1).
* `jsonrpc` (string; required): a JSON RPC spec used (example: 2.0).
* `method` (string; required): a method used for the request.
* `params` (array; required):
  1. `<string>` (data, 20 bytes): an address.
  2. `<string>` (quantity|tag): either the 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 number of transactions send from this address.

### `eth_estimateGas`

> Simulates a transaction and returns the estimated gas units it would consume.

The transaction will not be added to the blockchain. Note that the estimate may be significantly more than the amount of gas actually used by the transaction, for a variety of reasons including EVM mechanics and node performance.

#### Parameters

* `id` (integer; required): a request ID (example: 1).
* `jsonrpc` (string; required): a JSON RPC spec used (example: 2.0).
* `method` (string; required): a method used for the request.
* `params` (array; required):
  1. `<object>` (hex encoded): the transaction object:
     * `from` (string; data, 20 bytes; optional): the address the transaction is sent from.
     * `to` (string; data, 20 bytes; optional): the address the transaction is directed to.
     * `gas` (string; quantity; optional): the gas provided for the transaction execution. `eth_call` consumes zero gas, but this parameter may be needed by some executions.
     * `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.

### `eth_getBlockByNumber`

> Returns full block data for the block at the specified height.

#### Parameters

* `id` (integer; required): a request ID (example: 1).
* `jsonrpc` (string; required): a JSON RPC spec used (example: 2.0).
* `method` (string; required): a method used for the request.
* `params` (array; required):
  1. `<string>` (quantity|tag): either the 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.
  2. `<boolean>`: if `true` it returns the full transaction objects, if `false` — only the hashes of the transactions.

#### Returns

* `<object>`: a block object, or null when no block was found:
  * `number` (string; quantity): the block number; null when it's a pending block.

  * `nonce` (string; data, 8 bytes): the hash of the generated proof-of-work; null when it's a pending block.
  * `sha3Uncles` (string; data, 32 bytes): SHA3 of the uncles data in the block.
  * `logsBloom` (string; data, 256 bytes): the bloom filter for the logs of the block. null when its pending block.
  * `transactionsRoot` (string; data, 32 bytes): the root of the transaction trie of the block.
  * `stateRoot` (string; data, 32 bytes): the root of the final state trie of the block.

### `eth_getLogs`

> Returns all event logs matching an ad-hoc filter object, scoped by address, topics, and block range.

#### Parameters

* `id` (integer; required): a request ID (example: 1).
* `jsonrpc` (string; required): a JSON RPC spec used (example: 2.0).
* `method` (string; required): a method used for the request.
* `params` (array; required):
  1. `object`: the filter options:
     * `fromBlock` (string; quantity|tag; optional; default: "latest"): either the *block number* or one of the following *block tags*:
       * `latest`: for the last mined block.
       * `earliest`: for the lowest numbered block available on the client.
       * `pending`: for not yet mined transactions.
     * `toBlock` (string; quantity|tag; optional; default: "latest"): either the *block number* or one of the following *block tags*:
       * `latest`: for the last mined block.
       * `earliest`: for the lowest numbered block available on the client.
       * `pending`: for not yet mined transactions.
     * `address` (array of strings; data, 20 bytes; optional): a contract address or a list of addresses from which logs should originate.
     * `topics` (array of strings; data; optional): an array of 32 bytes data topics. Topics are order-dependent. Each topic can also be an array of data with "or" options.
     * `blockhash` (string; data, 32 bytes; optional; **future**): with the addition of EIP-234, `blockHash` will be a new filter option which restricts the logs returned to the single block with the 32-byte hash blockHash. Using blockHash is equivalent to `fromBlock = toBlock = the block` number with hash blockHash. If `blockHash` is present in the filter criteria, then neither `fromBlock` nor `toBlock` are allowed.

#### Returns

* `removed` (string; tag): `true` when the log was removed, due to a chain reorganization; `false` if it's a valid log.
* `logIndex` (string; quantity): the log index position in the block; null when it's a pending log.
* `transactionIndex` (string; quantity): the transactions index position log was created from; null when it's a pending log.
* `transactionHash` (string; data, 32 bytes): a hash of the transactions this log was created from; null when it's a pending log.
* `blockHash` (string; data, 32 bytes): a hash of the block containing the log; null when it's pending; null when it's a pending log.
* `blockNumber` (string; quantity): the number of the block containing the log; null when it's pending; null when it's a pending log.
* `address` (string; data, 20 bytes): an address from which this log originated.
* `data` (string; data): contains one or more 32 bytes non-indexed arguments of the log.
* `topics` (array of strings; data): an array of 0 to 4 32 bytes data of indexed log arguments. (In solidity: The first topic is the hash of the signature of the event (e.g. Deposit(address,bytes32,uint256)), except you declared the event with the anonymous specifier.)

#### `genesis_chunked`

> Retrieves Genesis in multiple chunks.

Gets genesis document in multiple chunks to make it easier to iterate through larger genesis structures. Each chunk is produced by converting the genesis document to JSON and then splitting the resulting payload into 16MB blocks, and then Base64-encoding each block.

**Parameters**

<br>

* `chunk` (integer; default: 0): a sequence number of the chunk to download.

**Returns**

A Genesis chunk response.

### 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> 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>).

Please refer to [Tendermint docs](https://docs.tendermint.com/v0.34/tendermint-core/using-tendermint.html#formatting) for formatting/encoding rules.

#### Parameters

<br>

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

}
```

***

#### `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> 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>).
3. A node is offline.

Please refer to [CometBFT docs](https://docs.cometbft.com/v0.34/core/using-cometbft.html#formatting) for formatting/encoding rules.

**Parameters**

<br>

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

**Request example**

{% tabs %}

```
curl https://rpc.crypto-chief.com/0g-testnet/{YOUR_API_KEY}/broadcast_tx_async?tx=<BASE64_ENCODED_TRANSACTION>
```

{% endtab %}
{% endtabs %}

**Response example**

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {

  }
}
```

***

#### `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](https://docs.cometbft.com/v0.34/core/subscription.html)).

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](https://docs.cometbft.com/v0.34/core/using-cometbft.html#formatting) for formatting/encoding rules.

**Parameters**
