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 token-sell-proceeds-shortfall-adjacent-period-changes-241b7ab2 -d '<json body>'
```

Example prompt: I have four token sale observations — the first had expected $100 and actual $94, the second expected $110 and actual $103.40, the third expected $100 and actual $94, the fourth expected $110 and actual $103.40 — can you run the adjacent period changes report on the proceeds shortfall for those?

## When to prefer this

Use this endpoint when you need a deterministic, inexpensive ($0.01 USDC) period-over-period shortfall change report for token sell observations, specifically the adjacent-period delta variant. Prefer it over generic financial analytics when working with token sale receipt data where you already have expected and actual USD values per period and need the change in shortfall between consecutive windows rather than a running total or absolute shortfall.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 items required
- More than 200 rows supplied — maxItems limit exceeded
- expected_usd set to 0 or omitted — exclusiveMinimum constraint violated
- Negative values for actual_usd or expected_usd — minimum:0 constraint violated
- Malformed row objects with extra properties — additionalProperties:false rejects them
- Network or payment failure — x402 payment of 0.01 USDC not processed

## How this service works

Token sell proceeds shortfall — Adjacent period changes: Adjacent period changes for Token sell proceeds shortfall. Supplied token observations only. Deterministic calculation or caller-threshold verdict, not a live scan, safety proof or trade recommendation. 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-over-period changes in token sell proceeds shortfall, computed deterministically from the supplied expected_usd and actual_usd observation rows. Outputs the delta in shortfall between each consecutive pair of periods, enabling trend analysis without live scanning or trade recommendations.
