# Wallet Inventory Trailing Mean Series + Keyed Dataset Comparison

> Wallet Inventory Trailing Mean Series + Keyed Dataset Comparison 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).

Computes a trailing mean time series and performs a keyed dataset comparison on two sets of wallet inventory records (token_units, reference_price) — up to 200 rows each, no external data sources.

## 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-keyed-dataset-comparison-f74f2765 -d '<json body>'
```

Example prompt: I have two sets of wallet inventory records — each up to 200 rows with token_units and reference_price fields — can you run a trailing mean series on the token_units field and also compare the two datasets keyed by row_id and instrument_group?

## When to prefer this

Choose this endpoint when you have two sets of wallet inventory records (up to 200 rows each) and need both a trailing mean smoothing analysis and a keyed row-by-row comparison in a single API call. It is ideal for offline/batch analytics on pre-collected portfolio snapshots where no live price lookup, prediction, or external data enrichment is required. It is cost-effective at $0.01 USDC for both reports simultaneously.

## Known failure modes

- Rows array is empty or missing — API returns a validation error
- More than 200 rows submitted — request rejected with max-items error
- Required fields (row_id, instrument_group, date, token_units, reference_price) missing from any row — validation error
- Date fields not matching YYYY-MM-DD pattern — pattern validation failure
- Mismatched row_ids between primary and comparison dataset — comparison may yield unmatched rows
- token_units or reference_price values outside allowed range (±1e12) — rejected
- Payment not attached or insufficient USDC — x402 payment required error

## How this service works

Wallet inventory — Trailing mean series + Keyed dataset comparison: Trailing mean series + Keyed dataset comparison 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 computed locally from the supplied data: (1) a trailing mean time series over the selected field (token_units or reference_price) across the provided rows, and (2) a keyed dataset comparison between the primary and secondary (other) dataset matched by row_id and instrument_group, highlighting differences per row. No external data is fetched or predicted.
