Action
Get Base Fee Estimates
Retrieves real-time estimates of Ethereum's base and transaction fees for the next five blocks.
Why this helps

- Retrieve base fee and blob base fee predictions for the next five blocks.
- See both 99% and 50% confidence estimates returned by the action.
- Keep the fee outlook attached to the incoming delivery request for review.

- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real request and check the returned confidence estimates.
Questions about this workflow
What does Blocknative return for this action?
It returns real-time predictions for base fee and blob base fee for the next five blocks, including 99% and 50% confidence estimates.
