# Wallet Inventory — Trailing Mean Series + Adjacent Row Changes

> Wallet Inventory — Trailing Mean Series + Adjacent Row Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).

Computes a trailing moving-average series and adjacent row-over-row changes for wallet inventory records (token_units or reference_price) over up to 200 supplied 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 wallet-inventory-trailing-mean-series-adjacent-row-changes-e23c60f8 -d '<json body>'
```

Example prompt: Can you run a trailing mean series with a window of 3 and adjacent row changes on my wallet inventory — I have rows for ETH and BTC holdings with dates, token_units, and reference_prices — and analyze the token_units field?

## When to prefer this

Choose this endpoint when you have pre-collected wallet inventory time-series data (up to 200 rows) and need both a smoothed trailing-mean trend and adjacent change detection in a single $0.01 call — with no external data lookups, predictions, or professional assessments needed. Prefer this over general-purpose analytics when you specifically need the dual-report (trailing mean + row changes) combination for token_units or reference_price fields.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds limit, request rejected
- Missing required row fields (row_id, instrument_group, date, token_units, reference_price) — validation error
- Window size smaller than 2 or larger than 200 — validation error
- Date strings not matching YYYY-MM-DD format — pattern validation failure
- Payment of 0.01 USDC not included — 402 Payment Required
- Null values in token_units or reference_price may affect trailing mean accuracy

## How this service works

Wallet inventory — Trailing mean series + Adjacent row changes: Trailing mean series + Adjacent row changes for supplied wallet inventory records (token_units, reference_price). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two analytical reports: (1) a trailing moving-average series for the selected field (token_units or reference_price) computed over the specified window size, and (2) adjacent row-over-row difference values between consecutive inventory records — both derived purely from the supplied data without any external lookups.
