assess_opportunity
Assess the best DeFi opportunity for a given capital amount and strategy.
This is the "cold start" tool â 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:
api_key: Your PreFlyte API key (required).
asset: Token symbol, e.g. "USDC", "WETH".
action: "supply" or "borrow".
position_size_usd: Capital amount in USD.
strategy: One of "yield_farming", "active_trading", "idle_capital".
chain: "ethereum", "arbitrum", or "any" (default: "any").
trades_per_day: For active_trading strategy only. Default 10.
Returns:
JSON with chain viability, ranked opportunities, gas analysis,
break-even calculations, and an actionable recommendation.

Returns all results in one response. If 'claims' is provided, single-claim
parameters are ignored.
Args:
api_key: Your PreFlyte API key (required).

"gas" â current base fee (gwei)
"utilization" â current pool utilization (%)
value: The numeric value you believe to be true.
operator: Comparison operator. One of:
"above" â actual must be >= value
"below" â actual must be <= value
"around" â actual must be within 10% of value
protocol: Required for supply_rate, borrow_rate, utilization.
Use "aave-v3" or "compound-v3".
chain: Chain name â "ethereum" or "arbitrum". Default "ethereum".
asset: Required for supply_rate, borrow_rate, price, utilization.
Use token symbol like "USDC", "WETH", etc.
claims: JSON-encoded array of claim objects for batch verification.
Each object contains: claim_type, value, operator, and optionally
protocol, chain, asset. When provided, single-claim params are ignored.
Returns:
Single mode: Dictionary with status (TRUE/FALSE), actual_value,
claimed_value, delta, delta_pct, data_timestamp, and summary.
Batch mode: Dictionary with 'mode', 'results' array, 'summary' counts,
and 'verified_at' timestamp.

Single:
verify_claim(api_key="...", claim_type="supply_rate", value=5.0,
