Request a five-block base fee forecast
When a transaction decision comes up, send a request and get Blocknative's next-five-block base fee and blob base fee predictions in a run report.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Base Fee Estimates
Retrieves real-time estimates of Ethereum's base and transaction fees for the next five blocks.
Why this helps
Preparing a transaction can mean looking up multiple fee components and confidence estimates at the moment you need them.
- Retrieve predictions for base fee and blob base fee across the next five blocks.
- Review the available 99% and 50% confidence estimates.
- Start a forecast on demand with a webhook request.
Setup
Build it in a few focused steps.
- 1Connect AnyDB and Blocknative once in Notis.
- 2Create an automation in plain language or in Automations, New Automation.
- 3In one instruction, ask Notis to retrieve and summarize Blocknative base fee and blob base fee predictions for the next five blocks.
- 4Choose the webhook trigger and select where run reports should go.
- 5Test with one real request and review both confidence estimates in the response.
