Check supported chains from the process that needs them
Start a chain metadata lookup from an existing internal request, then keep the result with its run report.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Supported Chains
Tool to retrieve supported chains metadata. use when discovering available networks for blocknative gas services.
Why this helps
When a process needs network coverage information, pausing to find the latest supported chain list adds avoidable context switching.
- Retrieve supported chain metadata when requested
- Start the lookup through an HTTP webhook
- Keep the result alongside a run report
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 supported chain metadata.
- 4Pick a webhook trigger and choose where run reports should go.
- 5Test with one real HTTP request to the webhook.
