# Token Volume Relative Change — Adjacent Period Changes

> Token Volume Relative Change — Adjacent Period Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).

Calculates the relative (percentage) change in token trading volume between adjacent time periods for a batch of token observations.

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-adjacent-period-changes-60486b87 -d '<json body>'
```

Example prompt: Can you calculate the relative volume change between periods for these token observations — current volume 150000 and previous volume 100000, plus current 165000 vs previous 110000 — and give me an adjacent period changes report?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, batch calculation of relative volume change between exactly two adjacent time periods (current vs previous) for up to 200 token observations at once. It is ideal for crypto volume momentum analysis, trading signal pipelines, or portfolio monitoring workflows where you already have paired current/previous volume figures and need percentage change results without a live market scan. Prefer this over general-purpose math APIs when working specifically with token volume data in a DeFi or crypto trading context.

## Known failure modes

- Fewer than 2 rows supplied — minimum array length is 2
- More than 200 rows supplied — maximum array length is 200
- Zero or negative values for current_volume or previous_volume (exclusiveMinimum: 0)
- Values exceeding the maximum supported volume (10^16)
- Malformed input object missing required current_volume or previous_volume fields
- Payment failure or insufficient USDC balance for the $0.01 call fee

## How this service works

Token volume relative change — Adjacent period changes: Adjacent period changes 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 adjacent period changes report.

## Output

A bounded adjacent period changes report containing the relative (percentage) change in token trading volume for each supplied current/previous volume pair, computed deterministically. Returns one result per input row — no live scan, safety proof, or trade recommendation is included.
