Request a five block fee outlook when needed

Let a transaction planning process request an outlook at the moment it needs one, then capture the estimate with the 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

Tool to get real-time predictions for base fee and blob base fee for the next 5 blocks. use when you need both 99% and 50% confidence estimates for upcoming blocks.

Why this helps

A fee outlook is useful at a decision point, but switching to a separate dashboard can break the flow that brought you there.

  • Request next five block predictions on demand
  • Include both base fee and blob base fee
  • Use the returned 99% and 50% confidence estimates

Setup

Build it in a few focused steps.

  • 1Connect Blocknative once in the Notis portal.
  • 2Create an automation in the portal or tell Notis in plain language to create one.
  • 3Describe the outcome in one instruction, such as retrieving and summarizing the next five block base fee estimates.
  • 4Pick a webhook trigger and choose where run reports should go.
  • 5Test with one real HTTP request at a fee decision point.

Questions about this workflow

Can the result include blob base fee?

Yes. The action retrieves predictions for both base fee and blob base fee for the next five blocks.

Does it predict a specific transaction's inclusion?

No. It provides base fee predictions with confidence estimates, not a transaction-specific inclusion guarantee.
