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
A result object indicating whether the provided address string is a valid Ethereum address (proper format and optional checksum), along with meta information about the call.
Example use cases
Example prompt
“Check whether '0x742d35Cc6634C0532925a3b844Bc454e4438f44e' is a valid Ethereum address.”
Technical details
Endpoint
POSThttps://finmath.qzqh5rrbkz.workers.dev/v1/eth_address_validateWhen to prefer
Use this endpoint when you need deterministic, exact Ethereum address validation rather than relying on an LLM's pattern-matching. Ideal before sending funds, registering an address, or ingesting user-supplied wallet addresses into a system. Prefer over ad-hoc regex checks when accuracy and auditability matter.
Side effects
- Missing required 'address' field returns validation error
- Non-string input may cause schema rejection
- Payment failure (402) if USDC balance is insufficient
- Malformed request body returns 4xx error
