## 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-buy-receipt-shortfall-ordered-trend-analysis-9ac344dd -d '<json body>'
```

Example prompt: Can you run an ordered trend analysis on these 4 token buy observations — I expected 1000 tokens but got 950, then expected 1100 and got 1045, then expected 1000 and got 950, then expected 1100 and got 1045 — and tell me whether the shortfall is trending better or worse?

## When to prefer this

Choose this endpoint when you need a deterministic, ordered trend computation on a sequence of token buy receipt shortfalls (expected vs. actual tokens received) without requiring live market data or real-time scanning. Ideal for post-trade auditing, bot monitoring, or evaluating fill quality drift across an ordered series of purchases. Not suitable for live price feeds, real-time safety checks, or generating trade signals.

## Known failure modes

- Fewer than 2 rows submitted — minimum of 2 observations required
- Row missing expected_tokens or actual_tokens field — schema validation failure
- expected_tokens set to 0 or negative — exclusiveMinimum constraint violated
- actual_tokens or expected_tokens exceed 10^16 — maximum constraint violated
- More than 200 rows submitted — maxItems constraint violated
- Payment not provided or insufficient — x402 payment required error

## How this service works

Token buy receipt shortfall — Ordered trend analysis: Ordered trend analysis for Token buy receipt 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 ordered trend analysis report.

## Output

A deterministic ordered trend analysis report covering the sequence of token buy shortfalls (expected minus actual tokens) across the submitted observation rows, including trend direction and a threshold-based verdict. Does not include live market data, safety assessments, or trade recommendations.
