# Introduction

> Introduction to the FelixFusion public API for datasets, pricing locations, and reports.

## What FelixFusion provides

FelixFusion provides a public read API for power-market datasets, pricing locations, and reports. You use it to discover datasets, query timeseries, inspect pricing locations, and pull report-style outputs from a stable HTTP interface.

The public API lives at `https://api.felixfusion.ai`.

## How the API is organized

* Public API routes live under `/v1`.
* API keys can be sent with `x-api-key` or `api_key`.
* Dataset routes support metadata lookup, data query, audits, and update history.
* Pricing-location routes support list, nearby, and single-location reads.
* Supported markets and market-specific dataset coverage are documented separately.
* The API reference tab documents the concrete endpoints in OpenAPI form.
