LayerZero Value Transfer API

Unified REST API for moving assets across 170 blockchains. One endpoint consolidates multiple bridge/swap protocols — you get a quote, sign the returned transactions, and poll for completion. Gas is paid on the source chain only.

Base URL: https://transfer.layerzero-api.com/v1

Auth (Starchild): the key is injected by sc-proxy — you do NOT set LAYERZERO_API_KEY. transfer.layerzero-api.com is a proxied domain, so route transfer calls through core.http_client and the platform adds the real key. The x-api-key header value can be anything (or omitted); the proxy overrides it.
