How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing the computed d1 and d2 scalar values (both as floating-point numbers), along with a schema identifier string ('delx/util-bs-d1-d2/v1') confirming the response format.
Example use cases
Option delta computation for a trading bot
“I need d1 and d2 for a call option — spot is 150, strike is 155, vol is 25%, it expires in 90 days (0.247 years), and the risk-free rate is 4.5%. I want to feed these into a delta calculation.”
At-the-money option pricing check
“What are the Black-Scholes d1 and d2 values for an at-the-money option where spot and strike are both 200, volatility is 30%, time to expiry is 1 year, and the risk-free rate is zero?”
Implied probability analysis for a short-dated option
“Give me d1 and d2 for a short-dated option: spot 50, strike 52, annualized vol 18%, expires in 2 weeks (0.038 years), risk-free rate 5%.”
