The LayerZero Scan Swagger API provides a comprehensive interface for programmatically tracking and analyzing crosschain messages and transactions. With this API, developers can:
  • Query Crosschain Messages: Search for messages by message ID, transaction hash, GUID, wallet address, or by endpoint and omnichain application (OApp) address.
  • Filter and List Messages: Retrieve lists of messages filtered by status (e.g., INFLIGHT, DELIVERED, FAILED), by specific pathways, or by monthly periods.
  • Access Detailed Transaction Data: Get detailed information on message states, including source and destination transaction details, verification statuses, and configuration metadata.
This API is particularly useful for monitoring bridging activities, tracking the progress of crosschain interactions, and integrating LayerZero data into dashboards or other analytical tools.
