# Benchmarks

Query station benchmark metrics for model evaluation and comparison.

## Query station benchmark metrics

> Query benchmark metrics (RMSE, MAE, quantiles) for forecast models evaluated against weather station observations.\
> \
> Useful for:\
> \- Comparing forecast model performance\
> \- Evaluating model accuracy by region\
> \- Analyzing forecast errors over time\
> \
> \*\*Multi-Model Support\*\*:\
> \- Query multiple models in a single request to compare performance\
> \- Results include model name in each row for easy comparison\
> \
> \*\*Geographic Filtering\*\*:\
> \- \`market\_zone\`: Filter by energy market zone (e.g., "DE", "FR")\
> \- \`country\_key\`: Filter by country code (e.g., "DE", "US")\
> \
> \*\*Note\*\*: Either \`station\_ids\` or \`geo\` must be provided (mutually exclusive).\
> \
> \*\*Authentication\*\*: Requires API key.\
> \
> For more information on benchmark metrics, see \[docs.jua.ai]\(<https://docs.jua.ai>).

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.jua.ai/api-v2/query-engine/open-api-reference/benchmarks.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
