```http
GET https://api.taostats.io/api/otc/listing/v2
```

Requires an API key in the `Authorization` header.

Returns currently active and historical sell-side listings on the Taostats OTC desk. A *listing* is a seller's offer to sell alpha for a subnet at a price expressed as a *basis-point offset* from the current market price (negative = discount, positive = premium). The executed price is snapped at the moment a buyer matches the listing.

Use this to discover available inventory, track listings by seller/hotkey/subnet, or filter by offset and amount bands. Pair with `/api/otc/offer/v2` (buy-side) and `/api/otc/trade/v2` (executed matches).

For the OTC marketplace UI see [taostats.io/otc](https://taostats.io/otc).
