Off-Chain Interface

Overview

The Airlift API provides programmatic access to available routes for bridging assets across chains, fee quotes for transfers, and transaction status. It supports fetching transaction metadata, querying available routes, and estimating costs for operations like bridging.

Pagination

For /routes endpoint, pagination metadata is included in the paging object:

  • prev: URI for previous page

  • next: URI for next page

  • self: URI for current page

Get Fee Quote

Endpoint: POST /quote

Security: API key

Query Parameters:

  • fromChain (string, required): Chain ID of source chain (e.g. 10).
