## Docs

- [Get Loop info](https://docs.loopscale.com/api-reference/data/loops/get-loop-info.md)
- [Get best quote](https://docs.loopscale.com/api-reference/data/markets/get-best-quote.md): Returns the top quote for each specified collateral asset based on available liquidity. This endpoint is designed for minimizing rate slippage for a borrow with known inputs.
- [Get quotes](https://docs.loopscale.com/api-reference/data/markets/get-quotes.md): Returns a list of current lend orders available for the specified principal token, collateral, and target duration. Results are sorted by APY and support pagination.
- [Get loan info](https://docs.loopscale.com/api-reference/data/positions/get-loan-info.md): Returns a list of loans filtered by request. Results support pagination.
- [Get strategies](https://docs.loopscale.com/api-reference/data/strategies/get-strategies.md): Returns a list of strategy data matching the filters.
- [Get collateral holders](https://docs.loopscale.com/api-reference/data/user/get-collateral-holders.md): Fetches a list of users and total balances for one or more specified collateral mints.
- [Get historical collateral holders](https://docs.loopscale.com/api-reference/data/user/get-historical-collateral-holders.md): Fetches a list of users and cumulative deposit seconds for a mint over a period of time.
- [Get Vault depositors](https://docs.loopscale.com/api-reference/data/user/get-vault-depositors.md): Fetches a list of users and total balances grouped by Vault.
- [Get Vaults](https://docs.loopscale.com/api-reference/data/vaults/get-vaults.md): Returns a list of raw Vault metadata and data that match filters.
- [Calculate Vault & Loop Metrics](https://docs.loopscale.com/api-reference/guides/vault-and-loop-metrics.md)
- [Loopscale API](https://docs.loopscale.com/api-reference/introduction/introduction.md)
- [Borrow principal](https://docs.loopscale.com/api-reference/transactions/borrow/borrow-principal.md): Borrows additional principal against an existing loan and can optionally refinance the targeted ledger in the same transaction.
- [Build loan](https://docs.loopscale.com/api-reference/transactions/borrow/build-loan.md): Builds or mutates a loan through a sequence of high-level actions. Supported step types currently include `repay`, `flashBorrow`, and `swapCollateral`.
- [Close loan](https://docs.loopscale.com/api-reference/transactions/borrow/close-loan.md): In the event a loan is fully repaid and all collateral is withdrawn, but wasn't closed, this directly closes the loan account and refunds the user.
- [Create loan](https://docs.loopscale.com/api-reference/transactions/borrow/create-loan.md): Creates a new loan with initial collateral and requested principal borrows, returning both the loan address and the serialized transaction needed to initialize it.
- [Deposit collateral](https://docs.loopscale.com/api-reference/transactions/borrow/deposit-collateral.md): Adds more collateral to an existing loan position.
- [Flash borrow](https://docs.loopscale.com/api-reference/transactions/borrow/flash-borrow.md): Atomically creates a new loan and executes optional CPIs before depositing collateral. Supports deferred collateralization. Returns a transaction message and resulting loan address.
- [Refinance loan](https://docs.loopscale.com/api-reference/transactions/borrow/refinance-loan.md): Update the duration of the loan.
- [Repay loan](https://docs.loopscale.com/api-reference/transactions/borrow/repay-loan.md): Partially or fully repay an active loan. Allows for the withdrawal of collateral for optional use in CPIs before repayment.
- [Sell ledger](https://docs.loopscale.com/api-reference/transactions/borrow/sell-ledger.md): Sells a loan ledger from one strategy into another strategy, using the expected sale price guard provided in the request.
- [Simple repay loan](https://docs.loopscale.com/api-reference/transactions/borrow/simple-repay-loan.md): A simplified repay endpoint that handles a single strategy at a time. Unlike the full repay endpoint, it does not support CPI instructions, collateral withdrawals, or setup instructions. If a ledger is fully repaid on a multi-ledger loan, weight matrix updates are automatically generated to redistri…
- [Swap collateral](https://docs.loopscale.com/api-reference/transactions/borrow/swap-collateral.md): Enables safe rebalancing of collateral by withdrawing a selected asset, executing CPIs (e.g. swaps or liquidity provision), and depositing a new asset in its place.
- [Withdraw collateral](https://docs.loopscale.com/api-reference/transactions/borrow/withdraw-collateral.md): Withdraws collateral from an existing loan. Full collateral removal may include internal weight-matrix and loan-lock handling before the transaction is returned.
- [Claim Orca fees](https://docs.loopscale.com/api-reference/transactions/clmm/claim-orca-fees.md): Claim accrued fees for an Orca CLMM collateral position on a loan.
- [Transfer Orca position](https://docs.loopscale.com/api-reference/transactions/clmm/transfer-orca-position.md): Reposition an Orca CLMM collateral position to a new tick range on an existing loan.
- [Transfer Raydium position](https://docs.loopscale.com/api-reference/transactions/clmm/transfer-raydium-position.md): Reposition a Raydium CLMM collateral position to a new tick range on an existing loan.
- [Update Orca liquidity](https://docs.loopscale.com/api-reference/transactions/clmm/update-orca-liquidity.md): Increase or decrease liquidity on an Orca CLMM collateral position while keeping the loan collateralized.
- [Update Raydium liquidity](https://docs.loopscale.com/api-reference/transactions/clmm/update-raydium-liquidity.md): Increase or decrease liquidity on a Raydium CLMM collateral position while keeping the loan collateralized.
- [Close strategy](https://docs.loopscale.com/api-reference/transactions/strategy/close-strategy.md): Closes an existing lending strategy and returns the serialized transaction required to do so.
- [Create strategy](https://docs.loopscale.com/api-reference/transactions/strategy/create-strategy.md): Creates a new lending strategy, deposits the initial principal amount, and may return multiple transactions when lookup-table setup or external yield account initialization is required.
- [Deposit into strategy](https://docs.loopscale.com/api-reference/transactions/strategy/deposit-strategy.md): Deposits additional principal into an existing lending strategy.
- [Update strategy](https://docs.loopscale.com/api-reference/transactions/strategy/update-strategy.md): Updates strategy settings and collateral terms. Large collateral-term updates may be split across multiple returned transactions.
- [Withdraw from strategy](https://docs.loopscale.com/api-reference/transactions/strategy/withdraw-strategy.md): Withdraws principal from an existing lending strategy, optionally closing out the full position.
- [Cancel vault timelocks](https://docs.loopscale.com/api-reference/transactions/vault/cancel-timelocks.md): Cancel one or more pending timelock entries.
- [Claim Vault rewards](https://docs.loopscale.com/api-reference/transactions/vault/claim-rewards.md): Claim rewards from a target lending Vault. This will harvest from all available rewards schedules and close empty accounts to refund SOL to requesting wallet.
- [Create rewards schedule](https://docs.loopscale.com/api-reference/transactions/vault/create-rewards-schedule.md): Create a new vault rewards schedule and optionally deposit reward tokens into it.
- [Create vault timelocks](https://docs.loopscale.com/api-reference/transactions/vault/create-timelocks.md): Create one or more timelock updates for vault collateral, rates, allocation, caps, and settings changes.
- [Deposit to Vault](https://docs.loopscale.com/api-reference/transactions/vault/deposit.md): Deposit funds into a target lending Vault. On an additional deposit, the previous stake account and reward schedule is deleted and a new one is created.
- [Edit vault deposits](https://docs.loopscale.com/api-reference/transactions/vault/edit-deposits.md): Enable or disable deposits for a lending vault.
- [Edit rewards schedule](https://docs.loopscale.com/api-reference/transactions/vault/edit-rewards-schedule.md): Edit an existing vault rewards schedule and optionally extend its end time while depositing additional rewards.
- [Withdraw from Vault](https://docs.loopscale.com/api-reference/transactions/vault/withdraw.md): Withdraw funds from a target lending Vault. If any deposits remain, the previous stake account and reward schedule is deleted and a new one is created.
