# GDP Implicit Price Deflator – Weighted Result Mean

> GDP Implicit Price Deflator – Weighted Result Mean 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).

Calculates a weighted mean of the GDP implicit price deflator across up to 200 supplied nominal/real GDP data rows using user-supplied nonnegative weights.

## 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-implicit-price-deflator-weighted-result-mean-b52b6268 -d '<json body>'
```

Example prompt: Calculate the weighted mean GDP implicit price deflator for these four period pairs — nominal GDP values of 1200, 1320, 1200, 1320 and real GDP values of 1000, 1100, 1000, 1100 — using weights of 1, 2, 1, 2 so the later periods count more.

## When to prefer this

Choose this endpoint when you have a set of nominal and real GDP observations and want a statistically correct weighted mean deflator rather than a simple arithmetic mean or a pooled ratio. It is ideal when different time periods, countries, or sectors should contribute unequally to the aggregate, and when you need the formula and units documented in the response for audit or reporting purposes.

## Known failure modes

- Fewer than 2 rows supplied — returns validation error
- Weights array length does not match rows array length — mismatch error
- Any weight is negative — rejected as invalid input
- Nominal or real GDP value is zero or negative — rejected by exclusiveMinimum constraint
- More than 200 rows supplied — exceeds maxItems limit
- Payment of 0.01 USDC not included or rejected — 402 Payment Required response

## How this service works

GDP implicit price deflator - Weighted result mean: Calculate a mean of up to 200 results using supplied nonnegative weights; not a pooled accounting ratio. Metric: GDP implicit price deflator. 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 weighted result mean report.

## Output

Returns a JSON object containing the weighted mean GDP implicit price deflator calculated from the supplied nominal and real GDP row pairs, along with the formula used, units, and stated limitations of the result. The result reflects only the supplied figures and is not pooled or drawn from a live data feed.
