# Bundle Contribution Base-100 Rebase Report

> Bundle Contribution Base-100 Rebase Report is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Calculates a base-100 rebased index of bundle contribution margins across multiple retail bundle scenarios, anchored to a chosen baseline row.

## 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 bundle-contribution-base-100-rebase-report-fe8c79a8 -d '<json body>'
```

Example prompt: Rebase my bundle contribution margins to a base-100 index using the first row as the baseline — I have four scenarios: bundle prices of 100, 110, 95, and 120 with item costs of 50, 55, 48, and 60, packing costs of 5, 5.5, 4.8, and 6, and fulfilment costs of 10, 11, 9.5, and 12.

## When to prefer this

Choose this endpoint when you need to normalize and compare retail bundle contribution margins across multiple pricing or cost scenarios using a base-100 index, particularly for scenario analysis or benchmarking against a reference bundle. It is a pure local calculation with no live data dependencies, making it fast and deterministic. Prefer it over raw margin calculators when you need relative indexed comparisons rather than absolute figures.

## Known failure modes

- Fewer than 2 rows supplied — minimum is 2 rows
- base_index out of range — must be between 0 and the number of rows minus 1
- Negative prices or costs — all values must be non-negative
- More than 200 rows submitted — exceeds maxItems limit
- Division by zero if baseline row has zero contribution margin
- Malformed row objects missing required fields (bundle_price, item_costs, packing_cost, fulfilment_cost)

## How this service works

Bundle contribution - Base-100 rebase report: Base-100 rebase report for Bundle contribution. Supplied retail figures only. Local calculation and scenario analysis; no live inventory, account access, platform fee lookup or order execution. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded base-100 rebase report deliverable.

## Output

A base-100 rebased report showing the contribution margin of each bundle row indexed relative to the chosen baseline row, enabling direct relative comparison of retail bundle profitability across up to 200 scenarios.
