# Treasury Supplied Balances — Daily Sum Series + Trailing Mean Series

> Treasury Supplied Balances — Daily Sum Series + Trailing Mean Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Computes daily sum aggregations and trailing moving-average series for treasury supplied balance records (opening and closing balances) over up to 200 rows.

## 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 treasury-supplied-balances-daily-sum-series-trailing-mean-series-84a469f3 -d '<json body>'
```

Example prompt: I have 50 rows of daily treasury balance data with opening and closing balances by instrument group — can you compute the daily sum series and a trailing mean series for the closing_balance field using a window of 7?

## When to prefer this

Choose this endpoint when you have already-collected treasury supplied balance data (up to 200 rows) and need both a daily sum aggregation and a trailing rolling mean in a single low-cost call. It is ideal for offline/batch analytical workflows where no live data lookup or external enrichment is needed — just fast local statistical computation on your own balance records.

## Known failure modes

- Fewer than 1 row supplied — validation error
- More than 200 rows supplied — request rejected
- Window size larger than number of rows — trailing mean may be empty or partial
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Balance values outside ±1,000,000,000,000 — rejected by schema
- Missing required fields (row_id, date, opening_balance, closing_balance, instrument_group) — validation error
- Payment not included or insufficient — 402 payment required

## How this service works

Treasury supplied balances — Daily sum series + Trailing mean series: Daily sum series + Trailing mean series for supplied treasury supplied balances records (opening_balance, closing_balance). 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 independent analytical reports: (1) a daily sum series aggregating the selected balance field (opening_balance or closing_balance) across all supplied rows by date, and (2) a trailing mean series computed over the specified rolling window — both derived entirely from the user-supplied treasury balance data, with no external data lookup.
