# Numora Options Pricing API

> Numora Options Pricing API is a paid API for AI agents from numormor.netlify.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Computes Black-Scholes options pricing (call or put) given spot price, strike price, time to expiry, risk-free rate, and volatility

## Facts

- Endpoint: POST https://numormor.netlify.app/api/financial/options
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-options-pricing-api-570894c2
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_PxbDq5D_LzuhXTVW0ScSu

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability numora-options-pricing-api-570894c2 -d '<json body>'
```

Example prompt: What's the theoretical price of a call option with a spot price of $150, strike price of $155, 3 months to expiry, a risk-free rate of 5%, and implied volatility of 25%?

## When to prefer this

Choose this endpoint when you need a pure serverless Black-Scholes options pricing computation with no external data dependencies — ideal when you already have all market parameters (spot, strike, expiry, rate, vol) and just need the math done accurately and cheaply via x402 micropayment on Base.

## Known failure modes

- Missing required fields (K, S, T, r, type, sigma) returns validation error
- Invalid option type value (not 'call' or 'put') causes computation failure
- Negative time to expiry or volatility may produce undefined or error results
- Payment failure via x402 micropayment results in 402 response before computation
- Very extreme parameter values (e.g. T=0, sigma=0) may produce edge-case or degenerate output

## How this service works

100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.

## Output

Returns a JSON object with success: true, a result object containing the computed option price and related Greeks or values, and a human-readable computation description string explaining what was calculated.
