How this service works
EXECUTION QUOTE (non-custodial): buy an unsigned, ready-to-sign transaction that deposits into or redeems from a stablecoin vault. Returns transaction_request {chainId,from,to,data,value} + route + risk summary + approval info. Barker NEVER broadcasts and never holds funds — return the transaction to YOUR user's wallet to sign; vault shares always go to signer_address…
Output
A JSON object containing a transaction_request with chainId, from, to, data, and value fields (ready to pass to a wallet for signing), along with the selected route, a risk summary for the vault, and any required token approval details. Vault shares or redeemed assets always go to signer_address. Barker never broadcasts the transaction.
Example use cases
Agent auto-deposits idle stablecoins
“My wallet 0xDe...5678 has 1000 USDC sitting idle — build me a deposit transaction into the top Barker yield pool (pool ID 'compound-v3-usdc-eth') for 1000000000 base units so I can sign it and start earning yield.”
Redeem vault position to stablecoins
“I want to pull out 250 USDC worth (250000000 base units) from my position in pool 'morpho-usdc-blue' — give me the unsigned redeem transaction for my wallet 0xFe...9999 to sign, with 1% slippage.”
DeFi portfolio rebalancing workflow
“As part of rebalancing my stablecoin portfolio, prepare a deposit transaction of 2000000000 base units into pool 'spark-usds-mainnet' for signer address 0x11...AAAA — I'll review and sign it myself.”
Technical details
Endpoint
GEThttps://mcp.barker.money/barker_execution_quote?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fully constructed, unsigned EVM transaction for a stablecoin vault deposit or redemption that the user's own wallet will sign — ensuring non-custodial execution. Prefer this over generic DeFi aggregators when you need Barker's route selection, risk summary, and guaranteed non-broadcast guarantee in one call.
Side effects
- Invalid pool_uid returns an error indicating the pool is not found or not executable
- Invalid or malformed signer_address causes a 400 validation error
- amount_base_units of zero or below minimum threshold returns an error
- Pool not available for the requested action (deposit vs redeem) returns unsupported action error
- Slippage too tight may return a route unavailable or insufficient liquidity error
- Network or RPC timeout may result in a 500 or timeout error
