How to estimate Ethereum gas prices with your AI

Connect Blocknative to your AI client to access live mempool data. Once connected, your agent can analyze pending transactions to suggest fee tiers.

Short answer

How can I use AI to predict Ethereum gas fees?

Your agent pulls live data from the Ethereum mempool to see what transactions are currently waiting to be processed. It then calculates the specific gas price tiers you need to ensure your transaction gets included in a block. This breakdown shows how the data flows from the mempool to your agent.

The outcomes

What your agent delivers

The data your AI pulls from the mempool results in these specific outputs.

DATA

Live mempool insights

The AI pulls current transaction data to show you exactly what the network is doing right now.

STRATEGY

Optimal fee tiers

Your agent suggests specific gas price levels based on the current congestion levels it sees.

DECISION

Human-led execution

The AI provides the numbers, but you decide which fee tier to actually use for your transaction.

LOGIC

Custom fee rules

You can ask your agent to build specific rules for when to use high or low gas fees.

The workflow

What your AI does when the data arrives.

The AI acts as a bridge between the live Ethereum mempool and your decision making.

  1. Fetch mempool state

    Your agent reaches out to the Blocknative API to see the current state of pending transactions.

    get_gas_prices

  2. Analyze congestion

    The AI looks at the volume and priority of transactions currently sitting in the mempool.

    get_gas_prices

  3. Calculate tiers

    It determines the different gas price levels required for immediate, standard, or slow inclusion.

    get_gas_prices

  4. Report findings

    Your agent presents the calculated fee tiers in a format you can use to set your transaction parameters.

  • Get the current Ethereum gas price tiers from the mempool.

  • Based on the current mempool data, what gas fee should I use for a high priority transaction?

  • Compare the current low, medium, and high gas price tiers.

  • Is the mempool currently congested enough to justify a higher gas fee?

FAQ

How this task behaves

  • 01

    Can the AI send my transaction to the blockchain?

    No. The AI only provides gas price data. You must manually sign and send your transaction using your own wallet or tool.

  • 02

    Does the AI update gas prices automatically?

    The AI only fetches the most recent data when you ask it to. It does not push live updates to you without a prompt.

  • 03

    Can the AI change my wallet settings?

    No. This MCP only reads mempool data. It has no access to your private keys or wallet configurations.

  • 04

    How accurate are these gas estimates?

    The estimates are based on real-time mempool data provided by Blocknative, but network conditions change every second.

  • 05

    Can I use this for Layer 2 networks?

    No. This specific tool is designed for Ethereum mainnet mempool data.
