## 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-record-ranking-359cfed8 -d '<json body>'
```

Example prompt: I have four Bitcoin block records — two with 0.125 BTC in fees and 3.125 BTC subsidy, and two with 0.1375 BTC fees and 3.4375 BTC subsidy — can you rank them by transaction fee share of the total mining reward?

## When to prefer this

Choose this endpoint when you need a structured, ranked comparison of multiple Bitcoin block records specifically by the proportion of mining reward attributable to transaction fees versus the block subsidy. It is well-suited for post-hoc analysis of historical blocks, mining pool benchmarking, or studying fee dominance trends, and is priced very low ($0.01 USDC) for single-call batch ranking of up to 200 records. It does not provide live prices or real-time data.

## Known failure modes

- Fewer than 2 rows submitted — minimum items violation
- subsidy_btc set to zero (exclusiveMinimum violation) — request rejected
- More than 200 rows submitted — maxItems exceeded
- Non-numeric or missing fee_btc/subsidy_btc fields — schema validation error
- Payment not processed — endpoint returns 402 Payment Required
