# Recoverable Mining Heat Value — Adjacent Period Changes

> Recoverable Mining Heat Value — Adjacent Period Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Calculates adjacent-period changes in recoverable mining heat value given energy consumption, heat price per kWh, and recoverable percentage across multiple time periods.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 recoverable-mining-heat-value-adjacent-period-changes-57876707 -d '<json body>'
```

Example prompt: Calculate the adjacent period changes in recoverable mining heat value for two periods: period 1 had 1000 kWh energy, $0.03 per kWh heat price, and 80% recoverable, and period 2 had 1100 kWh, $0.033 per kWh, and 88% recoverable.

## When to prefer this

Choose this endpoint when you need to compute period-over-period differences in recoverable mining heat value across a sequence of time periods with known energy consumption, heat price, and recovery percentage. It is purpose-built for adjacent period change analysis in mining heat recovery contexts, unlike generic financial diff tools or time-series databases. Prefer it when you need a formula-disclosed, unit-labeled report at low cost ($0.01 USDC) without needing live market prices or mining guarantees.

## Known failure modes

- Missing required fields (energy_kwh, heat_usd_per_kwh, recoverable_percent) returns validation error
- Fewer than 2 rows provided — minimum 2 rows required for adjacent comparison
- More than 200 rows submitted exceeds maxItems limit
- Zero or negative values for energy_kwh or heat_usd_per_kwh rejected due to exclusiveMinimum constraint
- recoverable_percent above 100 rejected
- Payment not included or insufficient — x402 payment of 0.01 USDC required per call

## How this service works

Recoverable mining heat value — Adjacent period changes: Adjacent period changes for Recoverable mining heat value. 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 adjacent period changes report.

## Output

A bounded adjacent period changes report showing the computed differences in recoverable mining heat value between each consecutive pair of input rows, based on supplied energy_kwh, heat_usd_per_kwh, and recoverable_percent values. The report includes the formula and units used but does not include live prices, active mining data, or guaranteed returns.
