## 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 transaction-fees-in-mining-reward-weighted-result-mean-b96b5c9c -d '<json body>'
```

Example prompt: Calculate the weighted mean of transaction fee share in mining rewards for these 4 blocks: fees of 0.125, 0.1375, 0.125, 0.1375 BTC and subsidies of 3.125, 3.4375, 3.125, 3.4375 BTC, using weights 1, 2, 1, 2.

## When to prefer this

Choose this endpoint when you need a statistically weighted summary of the transaction-fee fraction of Bitcoin mining block rewards across a batch of blocks, with configurable per-block weights to reflect varying importance or frequency. Prefer it over simple averages when blocks have different hash contributions, time periods, or pool sizes that should influence the aggregate result.

## Known failure modes

- Fewer than 2 rows or weights provided — minimum array length of 2 required
- Mismatched array lengths between rows and weights — arrays must be the same length
- subsidy_btc of 0 or negative — exclusiveMinimum enforced, will cause validation failure
- fee_btc or subsidy_btc values exceeding 1e16 — out of allowed range
- Non-numeric values in rows or weights arrays — schema validation error
- Payment not processed or insufficient USDC balance — x402 payment required

## How this service works

Transaction fees in mining reward — Weighted result mean: Weighted result mean for Transaction fees in mining 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 weighted result mean report.

## Output

A bounded weighted result mean report showing the weighted arithmetic mean of the transaction-fee-to-total-reward ratio across the supplied rows, computed using the provided weights array. The result is scoped to the supplied mining assumptions with formula and units disclosed; no live prices or guaranteed returns are included.
