# GDP per Capita Base-100 Rebase Report

> GDP per Capita 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 2026-10-18).

Rebases a series of GDP per capita values against a specified base observation, returning index-100 normalized values with formula, units, and limitations.

## 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 gdp-per-capita-base-100-rebase-report-3d405c88 -d '<json body>'
```

Example prompt: Rebase these GDP per capita observations to a base-100 index using the first entry as the base: GDP values [1000000, 1100000, 1050000, 1200000] with populations [1000, 1100, 1050, 1200] — give me the formula and any limitations too.

## When to prefer this

Choose this endpoint when you need to normalize a time series of GDP per capita values to a base-100 index against a specific reference observation, particularly when you have raw GDP and population data and want to express relative change from a baseline. It is purpose-built for this single economic metric and returns the formula and limitations alongside the result, making it suitable for transparent, auditable economic analysis workflows.

## Known failure modes

- Population value of zero causes division error (exclusiveMinimum enforced)
- base_index out of range (must be 0–199 and within the rows array length)
- Fewer than 2 rows supplied (minItems: 2 required)
- More than 200 rows supplied (maxItems: 200 enforced)
- GDP or population values exceeding 1,000,000,000,000 rejected
- Payment failure or insufficient USDC balance returns 402 error

## How this service works

GDP per capita - Base-100 rebase report: Rebase ordered calculated values against a supplied positive base observation. Metric: GDP per capita. Supplied figures only; returns JSON with formula, units and limitations. One of 50 calculators with 20 analysis modes. No live feed, financial advice or trade execution. 0.01 USDC includes one bounded base-100 rebase report report.

## Output

A JSON response containing the base-100 rebased GDP per capita index series calculated from the supplied GDP and population rows, along with the rebase formula applied, units used, and stated limitations of the calculation.
