# Normal Distribution CDF Calculator

> Normal Distribution CDF Calculator is a paid API for AI agents from kihustle.tech, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-10).

Computes the cumulative distribution function (CDF) of a normal distribution for a given value, mean, and standard deviation

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 normal-distribution-cdf-calculator-ce7396a0 -d '<json body>'
```

Example prompt: Calculate the cumulative probability for a normal distribution where x is 1.96, the mean is 0, and the standard deviation is 1 — I need the probability that the variable falls below that value.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call normal distribution CDF computation without setting up a local math library. Ideal for agents performing statistical hypothesis testing, risk assessment, or probability queries on the fly where running scipy or similar locally is not feasible.

## Known failure modes

- Missing required fields (x, mean, or std_dev) return an error
- Non-numeric inputs cause a validation failure
- std_dev of zero causes a division-by-zero or invalid distribution error
- Network or service unavailability returns a non-200 response

## Output

Returns a JSON object containing the computed CDF probability result (a value between 0 and 1 indicating the cumulative probability up to x) along with a success status field.
