# Exchanges and Entities

> Which venues back each family of market data, and what happens when you omit the exchange filter.

Endpoints that carry an `exchange` parameter accept the identifiers below, in lowercase.
**Omitting `exchange` leaves the query unfiltered by venue**, so the response spans every
venue that has data for that asset.

## Checking per asset

Venue coverage varies by asset — a small-cap listed on three exchanges will not answer for
44 of them. The authoritative, per-asset answer comes from the API itself:

* `GET /{asset}/ohlcv/exchanges` — venues with OHLCV for that asset
* `GET /{asset}/derivatives/Funding_Rate/exchanges` — venues with funding rate
* `GET /{asset}/derivatives/Open_Interest/exchanges` — venues with open interest
* `GET /{asset}/exchange_flow/entity_names` — entities tracked for on-chain flows
