## Tools (as reported by the server, not verified)

- `get\_returns`: Query historical DeFi lending returns from the ProfitLens engine. Returns real, empirically measured after-fee returns — not theoretical APY projections. Data is computed from on-chain index ratios every 30 min. Args: api\_key: Your PreFlyte API key \(required\). chain: Filter by chain — "ethereum" or
- `get\_ranking`: Get ranked list of best DeFi lending returns, sorted by net APY. Args: api\_key: Your PreFlyte API key \(required\). window\_days: Return window — 7, 14, 30, or 90 days. Default 7. strategy: "supply" or "borrow". Default "supply". top\_n: Number of top results. Default 10, max 30. Returns: Ranked list wi
- `get\_market\_snapshot`: Get current market snapshot for a specific lending market. Returns the latest rates, risk parameters, token price, and gas price. This is the foundation of RealityCheck — giving agents ground truth about current market conditions before they act. Args: api\_key: Your PreFlyte API key \(required\). prot
- `verify\_claim`: Verify factual claims about current DeFi market conditions. Supports two modes: - Single claim: provide claim\_type, value, operator \(and protocol/chain/asset as needed\). Returns one verification result. - Batch mode: provide a JSON-encoded array in 'claims'. Each element has the same fields \(claim\_t
- `assess\_opportunity`: Assess the best DeFi opportunity for a given capital amount and strategy. This is the "cold start" tool — call it first to understand where your capital is viable before making any moves. One call gives you chain viability, ranked opportunities, gas impact, and an actionable recommendation. Args: ap
- `gas\_timing`: Tell agents whether now is a good or bad time to transact, based on historical gas patterns. Compares current gas to 24-hour and 7-day averages, identifies the cheapest hours of the day, and estimates reference transaction costs. Args: api\_key: Your PreFlyte API key \(required\). chain: Chain name — "
- `check\_entry\_viability`: Before entering a lending position, verify that the market is actually open and has capacity. Checks market status \(active, frozen, borrowing enabled\), supply/borrow caps, and available liquidity. Returns a clear viable/not-viable verdict. Args: api\_key: Your PreFlyte API key \(required\). protocol: P
- `estimate\_net\_position`: Detailed financial estimate for a specific lending position — what will I actually earn \(or pay\) after gas costs? Combines current live rates, gas costs, and historical computed returns to project net yield over a holding period. Args: api\_key: Your PreFlyte API key \(required\). protocol: Protocol na
- `check\_pool\_viability`: Before swapping on Uniswap V3, check if pools have sufficient liquidity for the intended trade size. Finds all matching pools for a token pair, assesses trade impact relative to pool TVL, and recommends the best pool. Args: api\_key: Your PreFlyte API key \(required\). chain: Chain name — "ethereum" or
