# ASIC Efficiency Improvement — Adjacent Period Changes

> ASIC Efficiency Improvement — 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 2026-10-19).

Computes adjacent-period changes in ASIC miner energy efficiency (J/TH) to quantify improvement between old and new hardware configurations

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 asic-efficiency-improvement-adjacent-period-changes-fc633c17 -d '<json body>'
```

Example prompt: I upgraded my ASIC miners — the old ones ran at 25 J/TH and the new ones run at 20 J/TH. Can you run the adjacent period efficiency change calculation to show me how much the efficiency improved?

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.01 USDC) bounded computation of ASIC energy efficiency changes between periods, especially when comparing old vs. new hardware J/TH ratings in batch. Prefer this over a full mining profitability calculator when you only need the efficiency delta itself without live pricing, hashrate, or revenue projections.

## Known failure modes

- Input array has fewer than 2 row items — minimum of 2 pairs required
- Zero or negative J/TH values rejected (exclusiveMinimum:0 enforced)
- More than 200 row pairs supplied — maxItems limit exceeded
- Missing required old_jth or new_jth fields in any row object
- Payment not processed or insufficient USDC balance for x402 call

## How this service works

ASIC efficiency improvement — Adjacent period changes: Adjacent period changes for ASIC efficiency improvement. 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 report showing the adjacent-period change in ASIC energy efficiency (J/TH) for each supplied old/new pair, including deltas or percentage improvements. No live pricing, mining rewards, or guaranteed return figures are included — purely efficiency computation based on supplied assumptions.
