## 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-before-and-after-comparison-cca775ad -d '<json body>'
```

Example prompt: Compare transaction fee share in Bitcoin mining rewards: before the scenario the fee was 0.125 BTC and subsidy was 3.125 BTC, and after the scenario the fee is 0.1375 BTC and subsidy is 3.4375 BTC — give me the before and after breakdown report.

## When to prefer this

Choose this endpoint when you need a structured, quantitative before/after comparison of how transaction fees contribute to Bitcoin mining block rewards under two distinct scenarios with user-supplied assumptions. Ideal for mining economists, pool operators, or educators who want a bounded, formula-transparent report without live market data dependencies.

## Known failure modes

- Missing required field (fee_btc or subsidy_btc) returns validation error
- subsidy_btc of zero is rejected (exclusiveMinimum constraint)
- Negative values rejected by minimum:0 constraint
- Extremely large values may produce valid but practically meaningless results
- Payment failure (x402 protocol) prevents report generation
