Fetch gas estimates at the point your process needs them

Let the process that needs a fee estimate request it directly, then review the result in the run report.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Get Gas Prices

Tool to fetch gas price estimates for specific inclusion probabilities. use when you need gas price ranges for the next block or next ~10 seconds.

Why this helps

Manual fee lookups interrupt operational flows when another internal step already knows an estimate is needed.

  • Start gas estimate retrieval through an HTTP request
  • Use specified inclusion probabilities for planning
  • Keep the lookup within an existing internal flow

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, including the inclusion probabilities to request.
  • 4Pick a webhook trigger and choose where run reports should go.
  • 5Test with one real HTTP request for a gas estimate.

Questions about this workflow
