## 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`):

Example prompt: What's the current petrol and diesel price in Germany compared to the EU average — and how have prices changed over the last 52 weeks? Show me with and without taxes.

## When to prefer this

Choose this endpoint when you need authoritative, source-attributed EU fuel price data (petrol or diesel) with tax breakdowns, country rankings, and time-series history up to 10 years back. It is specifically tailored for Germany-vs-EU comparisons and EU Weekly Oil Bulletin data. Prefer it over generic energy APIs when the user asks about pump prices in EU countries, tax components of fuel prices, or cross-country EU fuel price comparisons.

## Known failure modes

- 503 Service Unavailable: returned (without charge) if the underlying EU Weekly Oil Bulletin data is more than 9 days old — source data may not yet have been published
- Invalid country code: passing an unrecognized or non-EU ISO 2-letter code may return an error or empty result
- weeks parameter out of range: values below 1 or above 520 will be rejected by schema validation
- No data available for very old weeks: historical depth may be limited beyond certain years

Use when asked what petrol or diesel costs in Germany or another EU country, how prices changed, or how Germany compares with the EU average. Source-attributed.
