# Budget Variances Base-100 Series and Equal-Width Histogram

> Budget Variances Base-100 Series and Equal-Width Histogram 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 a Base-100 indexed time series and an equal-width histogram for supplied budget variance records (budget_amount vs actual_amount) using local analytical engines.

## 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 budget-variances-base-100-series-and-equal-width-histogram-8f49f1f8 -d '<json body>'
```

Example prompt: Take these budget variance records for Q4 2026 across group-a and group-b — with budget_amount and actual_amount for each row — and give me both a Base-100 series anchored to row 0 and an equal-width histogram with 5 bins, indexing on budget_amount.

## When to prefer this

Choose this endpoint when you have pre-collected budget and actual financial records and need both a time-indexed Base-100 series and a frequency histogram computed together in a single call. Ideal for offline variance analysis on up to 200 rows without requiring any live data feed, external lookup, or prediction capability. Prefer this over generic analytics tools when you need these two specific report types (Base-100 + histogram) delivered together at low cost ($0.01 USDC for both).

## Known failure modes

- Rows exceed 200-item limit — request rejected
- Missing required fields (row_id, date, budget_amount, actual_amount, instrument_group) — validation error
- Date field not in YYYY-MM-DD format — schema validation failure
- base_index out of range for supplied row count — error or undefined behavior
- bins value outside 1–30 range — validation error
- Null values in budget_amount or actual_amount may affect computation results

## How this service works

Budget variances — Base-100 series + Equal-width histogram: Base-100 series + Equal-width histogram for supplied budget variances records (budget_amount, actual_amount). 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 for the supplied data: (1) a Base-100 indexed series showing relative movement of the chosen field (budget_amount or actual_amount) from the specified base row, and (2) an equal-width histogram dividing the chosen field into the requested number of bins with frequency counts — all computed locally without external lookups.
