# Bitcoin Mining Fee-to-Reward Ratio IQR Outlier Flags

> Bitcoin Mining Fee-to-Reward Ratio IQR Outlier Flags 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).

Analyzes a batch of Bitcoin mining reward records and flags which fee/subsidy observations are statistical outliers using the interquartile range (IQR) method.

## 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-fee-to-reward-ratio-iqr-outlier-flags-b0112da3 -d '<json body>'
```

Example prompt: I have 4 Bitcoin mining reward records — fees of 0.125, 0.1375, 0.125, and 0.1375 BTC against subsidies of 3.125, 3.4375, 3.125, and 3.4375 BTC — can you run IQR outlier detection on the fee-to-reward ratios and flag which ones are anomalous?

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.01 USDC), statistically principled IQR-based outlier check specifically for Bitcoin transaction fee vs. block subsidy data. It is ideal for validating mining assumptions in batches of up to 200 rows. Prefer it over general statistics APIs when you want a pre-packaged mining-domain preset with disclosed formula and units, and you do not need live market prices or return guarantees.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 required for IQR computation
- More than 200 rows supplied — maxItems limit exceeded
- subsidy_btc of exactly 0 rejected — exclusiveMinimum enforced
- Negative fee_btc or subsidy_btc values rejected
- Malformed JSON or missing required fields returns validation error
- Payment of 0.01 USDC not confirmed — x402 payment required before processing

## How this service works

Transaction fees in mining reward — IQR outlier flags: IQR outlier flags 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 iqr outlier flags report.

## Output

Returns a bounded report per input row indicating whether that row's transaction fee relative to mining reward is an IQR outlier, along with the formula and units used. No live price data or guaranteed return projections are included — output is purely statistical flagging based on supplied mining assumptions.
