# PoolDataProvider

**🔹 Constructor**

* **constructor(address addressesProvider)** Initializes the contract with a reference to the Aave `PoolAddressesProvider`.

***

**🔹 Core getters**

* **ADDRESSES\_PROVIDER()** → `address` Returns the address of the `PoolAddressesProvider` linked to this instance.

***

**🔹 Token and reserve information**

* **getATokenTotalSupply(address asset)** → `uint256` Returns the total supply of the `aToken` for a given underlying asset.
* **getAllATokens()** → `TokenData[]` Returns a list of all `aTokens` (symbol + address) registered in the pool.
* **getAllReservesTokens()** → `TokenData[]` Returns a list of all underlying reserve tokens (symbol + address) supported in the pool.

***

**🔹 Risk management & configuration**

* **getDebtCeiling(address asset)** → `uint256` Returns the debt ceiling configured for a given asset.
* **getDebtCeilingDecimals()** → `uint256` Returns the number of decimals used for debt ceiling calculations.
* **getFlashLoanEnabled(address asset)** → `bool` Indicates whether flash loans are enabled for a given asset.
* **getInterestRateStrategyAddress(address asset)** → `address` Returns the address of the interest rate strategy contract used for a given asset.
* **getLiquidationProtocolFee(address asset)** → `uint256` Returns the protocol fee (in bps) charged during liquidation for a given asset.
* **getPaused(address asset)** → `bool` Returns whether the reserve is paused (no deposits/borrows allowed).
* **getReserveCaps(address asset)** → `(borrowCap, supplyCap)` Returns the configured borrowing and supply caps for the reserve.
* **getReserveConfigurationData(address asset)** Returns risk configuration parameters for the reserve, including:
  * decimals, LTV, liquidation threshold, liquidation bonus, reserve factor
  * flags for collateral usage, borrowing enabled, stable rate enabled, active/frozen status.
* **getReserveEModeCategory(address asset)** → `uint256` Returns the eMode (efficiency mode) category assigned to the asset.
* **getReserveTokensAddresses(address asset)** → `(aToken, stableDebtToken, variableDebtToken)` Returns the addresses of the tokens associated with a reserve.
* **getSiloedBorrowing(address asset)** → `bool` Indicates if the asset enforces siloed borrowing (only one type of asset can be borrowed when this one is used).
* **getUnbackedMintCap(address asset)** → `uint256` Returns the cap for unbacked `aToken` minting for the given reserve.

***

**🔹 Reserve state**

* **getReserveData(address asset)** Returns detailed reserve metrics:
  * unbacked liquidity, accrued treasury, total `aToken` supply
  * total stable/variable debt, liquidity & borrowing rates
  * average stable borrow rate, liquidity/variable indexes
  * last update timestamp.
* **getTotalDebt(address asset)** → `uint256` Returns the total debt (stable + variable) for a reserve.

***

**🔹 User-specific data**

* **getUserReserveData(address asset, address user)** Returns information about a user’s position in a given reserve:
  * `aToken` balance, stable and variable debts
  * principal stable debt, scaled variable debt
  * stable borrow rate, liquidity rate
  * last stable rate update, collateral usage status.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://colend.gitbook.io/home/abi/pooldataprovider.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
