How this service works
Paid HTTP endpoints for AI agents, settled in USDC on Base via the x402 protocol. No account, no API key — pay per call.
Output
Returns a JSON object containing the option's theoretical price plus four Greeks: delta (directional sensitivity), gamma (delta curvature), theta (time decay per day), and vega (sensitivity to volatility). If a market price is supplied instead of volatility, the implied volatility is solved and returned.
Example use cases
Options trade risk assessment
“I'm looking at a put option on a stock trading at $200 with a strike of $195, 0.5 years to expiry, implied vol of 25%, and a risk-free rate of 4.5% — can you give me the theoretical price, delta, and gamma so I can size my position?”
Implied volatility extraction
“A call option with spot $100, strike $105, 90 days to expiry (0.247 years), and risk-free rate 5% is trading at $3.50 in the market — what's the implied volatility?”
Options portfolio hedging
“What's the delta and vega on a call option where the underlying is at $50, strike is $52, time to expiry is 0.1 years, vol is 30%, and rate is 3%? I need to figure out how many shares to hold to delta-hedge.”
Technical details
Endpoint
GEThttps://api.neuroterminal.xyz/v1/option-priceWhen to prefer
Use this endpoint when you need fast, stateless Black-Scholes option pricing and Greeks without signing up for a brokerage API or a financial data subscription. It's ideal for AI agents that need to evaluate option fair value, compute hedge ratios, or extract implied volatility on-the-fly with pay-per-call USDC micropayments and no API key overhead.
Side effects
- Missing required parameters (spot, strike, years) returns a 400-level error
- Providing both vol and price simultaneously may return ambiguous or undefined behavior
- Non-positive values for spot, strike, or years may cause mathematical errors in Black-Scholes
- Payment failure or insufficient USDC balance causes a 402 Payment Required response
- Very deep in-the-money or out-of-the-money options with extreme parameters may yield near-degenerate Greeks
