How this service works
Deterministic finance and crypto math for AI agents: TradFi (NPV, IRR, XIRR, Black-Scholes + Greeks, bonds, VaR, Sharpe) and DeFi (impermanent loss, perp liquidation, funding, Uniswap v3, health factor, cost basis). Exact, model-free arithmetic that LLMs get wrong — priced per call in USDC.
Output
Returns a result object containing the computed staking yield (total accumulated value or interest earned) along with a meta object containing calculation metadata such as inputs and method used.
Example use cases
Example prompt
“I'm staking 10,000 USDC at a 7.5% APR compounded daily (365 times per year) for 2 years — what will my total staking yield be?”
Technical details
Endpoint
POSThttps://finmath.qzqh5rrbkz.workers.dev/v1/staking_yieldWhen to prefer
Use this endpoint when you need exact, deterministic compound interest or staking yield calculations — especially for DeFi staking positions where LLM arithmetic would be unreliable. Prefer this over general-purpose LLM math when precision matters, when the user provides a specific APR and compounding schedule, or when auditable, reproducible results are required.
Side effects
- Missing required fields (apr, principal, compounds_per_year) returns a validation error
- Non-numeric values for numeric fields return a 400 error
- APR of 0 or negative principal may return edge-case or zero results
- Payment failure (402) if USDC payment is not included or insufficient
- Very large compounds_per_year values (e.g. continuous compounding) may hit precision limits
