# ASIC Repair Simple Payback — Sequential Input-Change Attribution

> ASIC Repair Simple Payback — Sequential Input-Change Attribution 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 how a change in repair cost or restored daily revenue shifts the simple payback period for an ASIC miner repair, attributing the delta sequentially to each input change.

## 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-repair-simple-payback-sequential-input-change-attribution-48a58278 -d '<json body>'
```

Example prompt: My ASIC repair used to cost $200 with $4/day restored revenue, but now the repair quote is $220 and restored daily earnings are $4.40 — show me a sequential waterfall breakdown of how those two input changes each contribute to the shift in simple payback period.

## When to prefer this

Choose this endpoint when you need to understand not just the before/after payback period for an ASIC repair, but specifically how much each changed assumption (repair cost vs restored daily revenue) individually contributes to the shift — useful for sensitivity analysis, explaining variance, or presenting a waterfall-style breakdown to stakeholders. Prefer this over a single-calculation endpoint when two or more inputs changed simultaneously and you need attribution rather than just a net result.

## Known failure modes

- repair_usd or restored_daily_usd set to zero or negative — rejected by exclusiveMinimum:0 constraint
- Missing required fields in before or after objects returns validation error
- Extremely large values (approaching 10^16) may cause numerical precision issues
- Payment of 0.01 USDC not confirmed via x402 protocol results in 402 response

## How this service works

ASIC repair simple payback — Sequential input-change attribution: Sequential input-change attribution for ASIC repair simple payback. 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

Returns a bounded sequential input-change attribution report showing the simple payback period before and after the scenario change, with each input's contribution to the payback period delta identified in sequence (repair cost change attributed first, then restored daily revenue change), using only supplied assumptions and disclosed formula. No live prices or guaranteed returns.
