# Token Buy Receipt Shortfall — Threshold Classification

> Token Buy Receipt Shortfall — Threshold Classification 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).

Classifies whether token buy receipt shortfall values fall within caller-defined lower and upper thresholds across a batch of expected vs. actual token observations.

## 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-threshold-classification-c2e3ee17 -d '<json body>'
```

Example prompt: I bought tokens and keep getting fewer than expected — can you classify whether the shortfall in these 4 transactions is within my acceptable range? Expected vs actual: 1000/950, 1100/1045, 1000/950, 1100/1045 — flag anything outside a lower bound of 0 and upper bound of 5.

## When to prefer this

Use this endpoint when you need a deterministic, batch threshold classification of token buy receipt shortfalls — i.e. you already have expected and actual token amounts and want to know whether each shortfall sits within caller-defined bounds. Prefer this over generic slippage calculators when you want a structured pass/fail verdict per row rather than a raw percentage, and when you need to evaluate up to 200 rows in one call at low cost ($0.01 USDC).

## Known failure modes

- Fewer than 2 rows supplied — minItems validation error
- expected_tokens is 0 or negative — exclusiveMinimum violation
- actual_tokens or expected_tokens exceeds 1e16 — maximum exceeded
- More than 200 rows submitted — maxItems exceeded
- lower threshold greater than upper threshold — may produce no classifications or unexpected results
- Malformed row objects with extra properties — rejected by additionalProperties:false
- Payment not included or insufficient — x402 payment required error

## How this service works

Token buy receipt shortfall — Threshold classification: Threshold classification 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 threshold classification report.

## Output

A bounded threshold classification report indicating, for each row of expected vs. actual token observations, whether the computed shortfall falls within the caller-specified lower and upper bounds. Results are deterministic verdicts based on supplied data only — not a live scan, safety proof, or trade recommendation.
