# Token Average Reported Trade Notional — Adjacent Period Changes

> Token Average Reported Trade Notional — 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 2026-10-12).

Computes adjacent period-over-period changes in the average reported trade notional (volume_usd / trades) for a token across a supplied sequence of observation rows.

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-average-reported-trade-notional-adjacent-period-changes-e64a9723 -d '<json body>'
```

Example prompt: Can you calculate the adjacent period changes in average trade notional for this token? I have 4 observation periods: period 1 had 200 trades and $100,000 volume, period 2 had 220 trades and $110,000 volume, period 3 had 200 trades and $100,000 volume, and period 4 had 220 trades and $110,000 volume.

## When to prefer this

Choose this endpoint when you need a deterministic, low-cost ($0.01 USDC) computation of consecutive period changes in average token trade notional from your own supplied observation data, rather than a live market scan or recommendation engine. It is ideal for batch analytics pipelines, report generation, and pre-processing steps where you control the input data and need period-delta calculations on up to 200 rows.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 observation rows required
- More than 200 rows supplied — maxItems constraint violated
- trades or volume_usd values of zero or negative — exclusiveMinimum constraint fails
- Malformed row objects or extra properties rejected by additionalProperties:false
- Payment failure or insufficient USDC balance for the $0.01 per-call fee

## How this service works

Token average reported trade notional — Adjacent period changes: Adjacent period changes for Token average reported trade notional. 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 showing the differences in average reported trade notional (volume_usd divided by trades) between each consecutive pair of supplied observation rows. Output is a deterministic calculation result, not a live scan or trade recommendation.
