# Market Data

> Read-only yields, loan markets, asset prices and perps data across every venue Compass supports. No wallet needed.

Every Compass product exposes the data behind it through read endpoints. They need only an API key, work without a wallet, and are included in the free plan, so you can build rate comparisons, dashboards or reports before your users make a single transaction.

| Data | What you get |
| - | - |
| **Vault yields** | [Morpho and Euler vaults](/v2/api-reference/earn/list-vaults) with 7, 30 and 90-day APY, TVL, available liquidity and deposit cap. Filter by chain, asset or minimum size. |
| **Aave rates** | [Supply and borrow APY](/v2/api-reference/earn/list-aave-markets) for every Aave market, averaged over the window you choose (30 days by default), per chain. |
| **Fixed yields** | [Pendle markets](/v2/api-reference/earn/list-pendle-markets) with implied APY, maturity and TVL. |
| **Loan markets** | Curated [Morpho](/v2/api-reference/credit/list-curated-morpho-markets) and [Euler](/v2/api-reference/credit/list-curated-euler-markets) markets with LTV, rates and liquidity. |
| **Tokenized assets** | The [catalog](/v2/api-reference/tokenized-assets/list-markets) of equities, RWA yield tokens and funds with price or NAV, APY and TVL, plus [per-asset detail](/v2/api-reference/tokenized-assets/get-a-market): 52-week range, volume, market cap, holder count, trading hours and candles. |
| **Perps markets** | [Stock, commodity and FX perps](/v2/api-reference/perpetual-trading/list-perpetual-trading-markets) with open interest, 24h volume, funding rate and max leverage, plus [OHLCV candles](/v2/api-reference/perpetual-trading/get-ohlcv-candles). |

## Example

The three highest-yielding USDC vaults on Base with at least \$1M available to withdraw:

```bash theme={"system"}
curl -G https://api.compasslabs.ai/v2/earn/vaults \
  -H "x-api-key: $COMPASS_API_KEY" \
  -d chain=base \
  -d asset_symbol=USDC \
  -d min_liquidity_usd=1000000 \
  -d order_by=apy_30d \
  -d direction=desc \
  -d limit=3
```

APYs are percentages: `"5.3282"` means 5.33%.
