## 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 pool-payout-vs-expected-reward-distribution-histogram-330ba5a1 -d '<json body>'
```

Example prompt: Can you generate a distribution histogram of my mining pool payouts versus expected rewards? I have 4 rounds of data — expected 0.01 BTC but received 0.011, expected 0.011 and got 0.0121, and the same two pairs repeated — split it into 5 bins.

## When to prefer this

Choose this endpoint when you have multiple Bitcoin mining round records and want to statistically characterize how pool payouts deviate from theoretical expected rewards. It is ideal for auditing pool reliability, detecting systematic under- or over-payment, or presenting distribution analytics to stakeholders. Prefer this over simple average comparisons when you need a full distributional picture (spread, skew, frequency by deviation bucket) rather than a single summary metric.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 data points required
- More than 200 rows submitted — exceeds maximum row limit
- received_btc or expected_btc set to zero or negative — both must be strictly positive
- bins parameter exceeds 30 or is less than 1 — must be between 1 and 30
- Missing required fields received_btc or expected_btc in one or more row objects
- Payment of 0.01 USDC not received — request rejected by x402 payment gate

## How this service works

Pool payout versus expected reward — Distribution histogram: Distribution histogram for Pool payout versus expected reward. Supplied mining assumptions only; formula and units disclosed. No live prices, mining or guaranteed return. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded distribution histogram report.

## Output

A bounded distribution histogram report showing how actual pool payouts deviate from expected BTC rewards, organized into a specified number of bins. Each bin captures the frequency of payout deviations falling within that range, enabling statistical analysis of pool accuracy and consistency.
