## Response Parameters

| Field  | Type   | Description                                                           |
| ------ | ------ | --------------------------------------------------------------------- |
| result | string | Suggested priority fee per gas in MON-wei (hex). 0x77359400 = 2 Gwei. |

## Use Case

The `eth_maxPriorityFeePerGas` method is essential for:

* EIP-1559 transaction construction
* Priority fee estimation
* Transaction speed optimization
* Wallet gas settings
* Automated trading fee calculation
* Dynamic fee adjustment

## Error Handling

| Status Code | Error Message | Cause                            |
| ----------- | ------------- | -------------------------------- |
| 403         | Forbidden     | Missing or invalid ACCESS-TOKEN. |

## Web3 Integration

{% tabs %}
{% tab title="Ethers.js" %}
{% code title="ethers-example.js" overflow="wrap" %}

```javascript
import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider('https://go.getblock.io/<ACCESS-TOKEN>/');

// Get fee data (includes maxPriorityFeePerGas)
const feeData = await provider.getFeeData();

console.log('Max Priority Fee:', ethers.formatUnits(feeData.maxPriorityFeePerGas, 'gwei'), 'Gwei');

// Build EIP-1559 transaction
const tx = {
    to: recipientAddress,
    value: ethers.parseEther('1.0'),
    maxFeePerGas: feeData.maxFeePerGas,
    maxPriorityFeePerGas: feeData.maxPriorityFeePerGas
};

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.getblock.io/api-reference/monad-mon/eth_maxpriorityfeepergas-monad.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
