How this service works
Expiry profit and loss for a long or short call or put: break-even, maximum gain and loss, and a payoff table.
Output
Returns a structured object including the break-even price, maximum gain (string, e.g. 'unlimited' for long calls), maximum loss (number), a payoff table of profit/loss values across a range of prices at expiry, P&L at a specific spot price, total premium paid/received, and a natural language summary and verdict about the position.
Example use cases
Evaluating a long call trade
“I'm thinking about buying a call option on a stock with a $200 strike price and paying a $6 premium per share. The stock is trading at $215 at expiry — can you calculate my profit or loss, break-even price, and max gain for 1 contract?”
Assessing downside risk on a short put
“I sold a put option with a $100 strike and collected a $3.50 premium. What's my maximum loss, break-even, and payoff if the stock ends up at $90 at expiry? I have 2 contracts.”
Checking covered call income potential
“I wrote a short call at a $180 strike and received a $5 premium per share. Walk me through the break-even, max gain, and a payoff table for that position — just 1 contract.”
Technical details
Endpoint
GEThttps://invest-math.x402tookit.com/option-payoff?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need precise quantitative options payoff analysis at expiry — especially break-even, max gain/loss, and a full payoff table — for a single-leg long or short call or put. Prefer this over general financial calculators when the user is analyzing a specific options position's risk/reward profile with defined parameters. Not suitable for multi-leg strategies (spreads, straddles) or real-time options pricing (Black-Scholes).
Side effects
- Missing required query parameters (type, side, strike, premium) returns an error
- Invalid enum values for type (not 'call'/'put') or side (not 'long'/'short') cause rejection
- Numeric fields (strike, premium, spot) passed as strings may fail validation
- Payment of 0.02 USDC not fulfilled results in HTTP 402 Payment Required
- Extreme or nonsensical values (e.g. negative strike) may return degraded or null results
