# Getting CLMM Pools

### 1. Get All Pools

Use `sdk.Pool.getPoolsWithPage()` method to retrieve all pools.

#### Parameters

* `pagination_args`: Default to get all pool lists, supports pagination

#### Example

```typescript
async function getAllPools() {
  const pools = await sdk.Pool.getPoolsWithPage()
  console.log(`pool length: ${pools.length}`)
}
```

### 2. Batch Get assign Pools

Use `sdk.Pool.getAssignPools()` method to retrieve specific pools.

#### Parameters

* `assign_pools`: An array of pool ID to get.

#### Example

```typescript
const pools = await sdk.Pool.getAssignPools(assign_pools)
console.log(pools)
```

### 3. Get Single Pool

Use `sdk.Pool.getPool()` method to retrieve a specific pool.

#### Parameters

* `pool_id`: Pool address
* `force_refresh`: Optional boolean to refresh cache

#### Example

```typescript
const pool = await sdk.Pool.getPool(pool_id)
console.log({ pool })
```

### 4. Get Pool by Coin Types

Use `sdk.Pool.getPoolByCoins()` method to find pools by coin types.

#### Parameters

* `coins`: Array of coin types
* `fee_rate`: Optional fee rate number

#### Example

```typescript
const coin_type_a = '0x5d4b302506645c37ff133b98c4b50a5ae14841659738d6d733d59d0d217a93bf::coin::COIN'
const coin_type_b = '0xc060006111016b8a020ad5b33834984a437aaa7d3c74c18e09a95d48aceab08c::coin::COIN'

const pools = await sdk.Pool.getPoolByCoins([coin_type_a, coin_type_b])
```

### 5. Notes

Some common methods for pool

#### 1. Convert SqrtPrice to Price

Use `TickMath.sqrtPriceX64ToPrice()` method to convert a given sqrtPrice to a price.

#### Parameters

* `sqrt_price_x64`: The sqrtPrice value to convert.
* `decimals_a`: The number of decimals for coin A.
* `decimals_b`: The number of decimals for coin B.

#### Example

```typescript
const sqrt_price_x64 = '18446744073709551616'
const decimals_a = 6
const decimals_b = 9

const price = TickMath.sqrtPriceX64ToPrice(new BN(sqrt_price_x64), decimals_a, decimals_b)
console.log('Price:', price.toString())
```
