# Bitcoin Mining Reward Fee Attribution — Sequential Input-Change Analysis

> Bitcoin Mining Reward Fee Attribution — Sequential Input-Change Analysis is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Computes how a change in transaction fee and block subsidy inputs sequentially affects mining reward share distribution, using a waterfall attribution model.

## 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 bitcoin-mining-reward-fee-attribution-sequential-input-change-analysis-5dfdae3f -d '<json body>'
```

Example prompt: Run a sequential input-change attribution on my mining reward: before it was 0.125 BTC in fees and 3.125 BTC subsidy, and after it changed to 0.1375 BTC in fees and 3.4375 BTC subsidy — show me the waterfall breakdown of how each input change contributed to the reward shift.

## When to prefer this

Choose this endpoint when you need to decompose a change in Bitcoin mining block rewards into the sequential marginal contributions of transaction fees versus block subsidy, following a defined waterfall methodology. It is ideal for miners, pool operators, or analysts who want to attribute reward deltas between two known states using a transparent formula. Prefer this over generic financial calculators when you specifically need a mining-context sequential attribution with disclosed assumptions and BTC-denominated inputs.

## Known failure modes

- subsidy_btc set to zero triggers exclusiveMinimum violation and request rejection
- missing required fee_btc or subsidy_btc in before/after objects returns validation error
- extremely large values near the maximum boundary may produce numerically degenerate attribution results
- no live price data is available so outputs are in BTC units only — fiat conversion not supported
- before and after objects with identical values yield a zero-delta attribution with no meaningful waterfall

## How this service works

Transaction fees in mining reward — Sequential input-change attribution: Sequential input-change attribution 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 sequential input-change attribution report.

## Output

A bounded sequential input-change attribution report that decomposes the change in total mining reward (fees + subsidy) between two states into its sequential contributions — showing how much the fee change and subsidy change each contributed to the shift in mining reward share, formatted according to the engine's disclosed formula and units.
