# Token Volume Relative Change — Threshold Classification

> Token Volume Relative Change — 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 2026-10-30).

Classifies whether the relative change between current and previous token trading volumes falls within caller-specified lower and upper thresholds, returning a deterministic verdict for each observation pair.

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-volume-relative-change-threshold-classification-cd9c25fc -d '<json body>'
```

Example prompt: Classify these token volume pairs against a lower threshold of -20 and upper threshold of 50: first pair is current 150000 and previous 100000, second pair is current 90000 and previous 120000 — tell me which observations fall outside those bounds.

## When to prefer this

Choose this endpoint when you need fast, deterministic classification of token trading volume relative changes against custom threshold bounds, especially for batch processing up to 200 observation pairs at a time. It is ideal when you supply your own historical and current volume data and need a structured pass/fail verdict rather than a live market scan or predictive recommendation. Prefer it over general analytics APIs when the specific output needed is a threshold-bounded classification verdict at low per-call cost.

## Known failure modes

- Fewer than 2 row observations submitted (minItems constraint violated)
- current_volume or previous_volume is zero or negative (exclusiveMinimum: 0)
- More than 200 rows submitted (maxItems constraint violated)
- Lower threshold is greater than upper threshold leading to empty valid range
- Non-numeric values provided for volume fields
- Network or payment failure returning 402 or 5xx status

## How this service works

Token volume relative change — Threshold classification: Threshold classification for Token volume relative change. 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

Returns a bounded threshold classification report for each submitted observation pair, indicating whether the relative change between current and previous volume falls within the specified lower and upper bounds. Results are deterministic and based solely on the supplied numeric inputs — not live market data.
