# List Markets

> List Limitless markets with filtering and sorting

List Limitless markets with filtering and sorting. Prices are normalized to 0-1 range. Data covers markets active from **March 7th, 2026**.

| Constraint | Value              |
| ---------- | ------------------ |
| `limit`    | 1–100 (default 20) |

### Trade Types

* `amm` - Automated market maker. `market_address` is populated with the AMM contract address.
* `clob` - Central limit order book. `exchange_address` is populated.

### Notes

* Prices are normalized to 0-1 range (AMM raw values may be 0-100 internally).
* `open_interest_usd` is currently available only for AMM markets. For CLOB markets, it is returned as `null` because Limitless does not expose CLOB open interest through the indexed market API today.
* `collateral` shows the settlement token (currently all USDC on Base).
* No event grouping - all markets are standalone.
