```http
GET https://api.taostats.io/api/otc/lockup/purchase/v1
```

Requires an API key in the `Authorization` header.

Returns lockup purchases — the moments a buyer committed TAO into a lockup listing's escrow account. Each row records the escrow account, executed price, TAO + alpha amounts, fee, and the `unlock_block` after which the buyer can call `claim` to take possession of the alpha. Filter by status (`pending`, `claimed`, `cancelled`) to see what's still in escrow.
