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 kihustle-bayes-probability-calculator-c0df7d82 -d '<json body>'
```

Example prompt: Calculate the Bayesian posterior probability for me: the prior probability of event A is 0.3, the probability of observing B given A is 0.8, and the probability of observing B given not-A is 0.2.

## When to prefer this

Choose this endpoint when you need a simple, fast, single-call Bayesian posterior computation from three probability inputs. It is ideal for agents that need to update beliefs based on evidence without building a full probabilistic model. Best for one-shot Bayes calculations rather than complex multi-variable inference networks.

## Known failure modes

- Missing required input fields (p_a, p_b_given_a, or p_b_given_not_a) may cause a processing error
- Probability values outside [0,1] range may produce invalid results or errors
- Division by zero if both P(B|A)*P(A) and P(B|not A)*P(not A) sum to zero
- Vague or non-numeric inputs will fail schema validation

## How this service works

## Output

Returns a JSON object with a 'result' field containing the computed posterior probability P(A|B) and a 'status' field indicating success. The posterior is calculated as P(A)*P(B|A) / [P(A)*P(B|A) + P(not A)*P(B|not A)].
