How this service works
VAULT POSITION (on-chain read): current redeemable value of a wallet's ERC-4626 vault position. Pass the pool_uid (from barker_executable_pools / barker_execution_quote) and the wallet address; Barker resolves the vault contract and reads balanceOf + convertToAssets directly on-chain, returning shares and current_value in the vault's underlying asset (value_asset, e.g. USDC).…
Output
Returns the wallet's current vault share balance (shares) and the present redeemable value in the vault's underlying asset (e.g. USDC), computed by calling balanceOf and convertToAssets on-chain. Also returns the value_asset identifier (e.g. USDC contract) so the caller knows which asset the value is denominated in.
Example use cases
Portfolio value check before withdrawal
“Before I redeem, can you tell me exactly how much USDC I'd get back from my position in the morpho-vault_base_usdc_0xee8f4ec5 pool for wallet 0xAbCd1234ef567890?”
DeFi position monitoring dashboard
“Pull the current vault shares and redeemable USDC value for wallet 0xDead...Beef in the barker pool aave-v3_base_usdc_0xabc12345 so I can update my portfolio tracker.”
Yield farming P&L calculation
“I deposited into a Barker vault a month ago — what are my current vault shares and their USDC value now for wallet 0x1234abcd in pool morpho-vault_base_usdc_0xee8f4ec5 so I can calculate my gains?”
Technical details
Endpoint
GEThttps://mcp.barker.money/barker_vault_positionWhen to prefer
Use this endpoint when you need the live, on-chain redeemable value of a specific wallet's position in a Barker-indexed ERC-4626 vault — particularly before executing a redemption, computing P&L, or monitoring portfolio value. Prefer this over APY/pool data endpoints when the question is 'how much is THIS wallet's position worth right now' rather than 'what is the pool's yield or TVL'.
Side effects
- Invalid or malformed wallet address (non-0x, wrong length) returns an error
- Unknown or unsupported pool_uid not found in Barker's index returns a not-found error
- Wallet address holds zero shares — returns zero shares and zero current_value
- On-chain RPC call failure or node unavailability may return a transient error
- Pool_uid referencing a non-ERC-4626 vault may return an unsupported error
