Check Ethereum gas prices before you submit
Get a timely fee estimate without switching tools or checking the mempool by hand.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Gas Prices
Retrieves gas price estimates for likely transaction inclusion.
Why this helps
A transaction is ready, but checking current fees adds another interruption and can delay sending it.
- Fetches Blocknative estimates for the requested inclusion probabilities.
- Keeps a fee check close to the transaction decision.
- Reports the returned estimates in the selected channel.
Setup
Build it in a few focused steps.
- 1Connect Aivoov and Blocknative once in the Notis portal.
- 2Create an automation from Automations, New Automation, or tell Notis in plain language from any channel.
- 3In one instruction, ask Notis to fetch Blocknative gas prices for the transaction context supplied with the webhook and summarize the returned estimates.
- 4Choose the webhook trigger and where run reports should go.
- 5Test with one real transaction context and review the returned estimate.
Questions about this workflow
Does this automation submit the transaction?
No. It fetches gas price estimates and reports them. It does not submit or alter a transaction.
What should the webhook include?
Include the chain or network context and the fee inclusion probabilities you want checked. The action description covers specific inclusion probabilities.
