Example prompt: Give me this week's EIA petroleum inventory brief — I want to know whether crude stockpiles built or drew down, by how much, and what it means for oil prices and the dollar.

## When to prefer this

Use this endpoint when you need a concise, trader-oriented analysis of the weekly EIA US petroleum inventory release, particularly when assessing crude oil supply dynamics and their implications for commodity-linked currencies (CAD, NOK) or broader macro positioning. Prefer this over raw EIA data feeds when you want pre-interpreted, actionable intelligence rather than raw numbers.

## Known failure modes

- EIA data not yet released for the current week — returns stale or no data
- Upstream EIA data source unavailable or delayed
- Payment not processed — returns 402 Payment Required
- Rate limiting or service overload on the Vercel deployment

## How this service works

Weekly EIA petroleum inventory intelligence for energy and macro agents — crude, gasoline and distillate builds and draws versus expectations, with the oil-price and CAD/NOK implications.

## Output

A structured weekly brief summarizing the latest US EIA petroleum inventory data, including crude oil and petroleum product stockpile changes, any surprise versus expectations, and macro/forex trading implications.
