# Check if there is a pending offramp that needs USDC sent to Coinbase

`GET /v1/offramp/pending-send`

Check if the authenticated user has a pending offramp withdrawal where Coinbase
has provided a deposit address (`to_address`). If so, the frontend should send
USDC from the user's Smart Account earnings wallet to that address.

**Polling pattern:** Frontend polls this every ~5 seconds after the user returns
from the Coinbase offramp UI.

If a pending event exists but Coinbase hasn't provided a deposit address yet,
this endpoint triggers a background Coinbase scan and returns `pending=True`
with `to_address=null`. The next poll will pick up the address after the scan.

## Headers
