Ideal for pre-trade validation across DeFi, DEX, perps, and cross-exchange arb strategies. Complements the ArbiPulse opportunity scanner and execution package endpoints by providing the cost layer between signal and execution. ## Known failure modes - Missing required trade parameters (entry/exit price, size) returns 400 error - Unsupported exchange or venue identifier returns validation error - Gas price out of range or zero returns computation error - Invalid slippage value (negative or >100%) returns 400 bad request - Payment not included or insufficient USDC returns 402 Payment Required ## How this service works Itemized fee breakdown and net P&L for any arbitrage trade — fees, slippage and gas. For arbitrage and trading agents. ## Output An itemized cost report including exchange/protocol fees per leg, estimated slippage cost in dollar terms, gas cost in USD, total cost sum, gross profit from the price differential, and final net P&L — giving the agent a clear go/no-go profitability signal for the trade. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET", "HEAD", "DELETE" ], "type": "string" }, "queryParams": { "type": "object", "properties": { "days": { "type": "string", "description": "holding period for yield arb in days" }, "gas_usd": { "type": "string", "description": "estimated gas cost in USD" }, "arb_type": { "type": "string", "description": "spot | yield | perps | flash | sports" }, "exit_price": { "type": "string", "description": "sell price (or deposit APY for yield arb)" }, "entry_price": { "type": "string", "description": "buy price (or borrow APY for yield arb)" }, "slippage_bps": { "type": "string", "description": "expected price impact in basis points" }, "flash_fee_bps": { "type": "string", "description": "flash loan fee in bps (0 for Balancer, 9 for Aave)" }, "taker_fee_bps": { "type": "string", "description": "exchange taker fee in basis points (e.g. 10 = 0.10%)" }, "bridge_fee_usd": { "type": "string", "description": "bridge cost for cross-chain arb (0 if same chain)" }, "trade_size_usd": { "type": "string", "description": "position size in USD, e.g. 10000" }, "withdrawal_fee_usd": { "type": "string", "description": "exchange withdrawal fee in USD" } } } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "errors": { "type": "object", "description": "Documented error responses, keyed by HTTP status code", "additionalProperties": { "type": "object", "required": [ "description" ], "properties": { "example": { "type": "object" }, "description": { "type": "string" } } } }, "example": { "type": "object" } } } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "inputs": { "gas_usd": 0.5, "arb_type": "spot", "exit_price": 67950, "entry_price": 67800, "slippage_bps": 5, "taker_fee_bps": 10, "trade_size_usd": 10000 }, "verdict": "NOT VIABLE — costs exceed spread", "suggestion": "This spot arb is marginal at $10k.
