Tools (12)

`barker_crosschain_routes`	Barker's cross-chain route availability for a stablecoin from a given chain (bridge/venue coverage). Use for 'bridge USDC from arbitrum', '跨链路径'. (paid: $0.01 per call via x402)
`barker_defi_vaults`	Query real-time stablecoin supply yield pools from Barker's index of 500+ DeFi protocols. Returns ranked rows with protocol_name, chain_name, asset_symbol, supply_apy_total (decimal — multiply by 100 for %), and supply_tvl (USD). Use for questions like 'best stablecoin yield', 'where to earn on USDC', 'compare lending rates', '稳定币利率'. (paid: $0.001 per call via x402)
`barker_executable_pools`	EXECUTION DISCOVERY: which stablecoin vaults in Barker's index support direct deposit/redeem through barker_execution_quote. Returns executable pools with adapter support, live deposit capacity (is_full) and APY/TVL. Call this before barker_execution_quote — every pool listed here can be quoted, and its pool_uid is the exact string that tool expects (its vault_token_address works there too). Skip this call entirely if you already know the vault contract address. All parameters are optional: call with no arguments to get the top executable pools across every asset. APY unit: decimal (0.05 = 5%). Use for 'which pools can my agent actually deposit into', '哪些池子能直接存'. (paid: $0.01 per call via x402)
`barker_execution_quote`	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 (receiver is not a parameter). Same-chain only (self/portals adapters). pool_uid takes EITHER a Barker pool_uid OR the vault contract address — if you already know the vault address, quote directly, no discovery call needed. Flow: barker_yield_advisor → barker_executable_pools → this tool → your user signs. Asset identity is resolved by the selected pool; symbols and underlying-asset token addresses are never accepted as identity (pass the VAULT contract, not the asset contract). If a pool has multiple possible underlying assets, the backend rejects ambiguity instead of guessing. Use for 'deposit 1000 USDC into this vault', '帮我把 USDC 存进这个池子（自己签名）'. (paid: $0.05 per call via x402)
`barker_market_overview`	Barker's stablecoin market snapshot: total market cap, yield-bearing cap, asset distribution, chain distribution. Use for 'stablecoin market cap', 'USDT market share', '稳定币市场份额'. share_pct fields are decimals (0.425 = 42.5%). (paid: $0.001 per call via x402)
`barker_market_trend`	Barker's historical APY trend for stablecoins vs. US Treasury benchmark over a lookback window (7–180 days). Use for 'DeFi vs treasury', 'is stablecoin APY going up', 'crypto yield trend', '稳定币利率走势'. (paid: $0.001 per call via x402)
`barker_paper_hedge_farm`	Papertrade (HyperEVM) hedge-farm snapshot: PAPER mint rate per USD lost, BTC/ETH mid prices and open-interest headroom, Barker's hosted fee and size limits. Pass margin (USDC per leg) with optional leverage / stop_pct / take_pct / budget to get a cost estimate (USDC per PAPER, loss and PAPER per stop). Read-only; the user starts the strategy at app.barker.money/paper. (paid: $0.001 per call via x402)
`barker_pool_detail`	Full single-pool dossier from Barker's index by pool_uid: all APY components (percent unit), TVL, terms, execution capability, reward breakdown. Use after barker_defi_vaults / barker_yield_advisor to inspect one pool. (paid: $0.005 per call via x402)
`barker_pool_history`	Per-pool APY/TVL time series from Barker's index (default 30d, APY percent unit) for trend and volatility analysis of one pool_uid. Use for 'is this pool's APY stable', '这个池子收益稳不稳'. (paid: $0.005 per call via x402)
`barker_pool_search`	Fuzzy search Barker's pool index by keyword (protocol name / pool name / asset). Resolves natural-language pool references to pool_uid for the detail/history tools. (paid: $0.001 per call via x402)
`barker_vault_position`	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). Barker does not store your deposit baseline — record the principal you deposited yourself; earned = current_value - your net deposits. Use after depositing via barker_execution_quote to monitor a position: 'how much is my vault position worth now', '我存进金库的 USDC 现在值多少'. (paid: $0.001 per call via x402)
`barker_yield_advisor`	FLAGSHIP: 'Where should I park my stablecoins right now?' Returns a ranked top-N recommendation across Barker's DeFi yield index (500+ protocols) with data-derived reasons and risk flags per pick (APY vs market median, TVL depth, incentive-dependence, lock terms). Use for 'best place for my USDC', '钱放哪收益最好', 'recommend stablecoin yield with low risk'. APY unit: percent (6.2 = 6.2%). (paid: $0.03 per call via x402)
