# Introduction

This documentation introduces the FinImpulse API, a solution for accessing normalized financial data across different asset classes. The API is intended for developers and analysts who need consistent, up-to-date information for building investment tools, portfolio analytics, or financial automation.

## REST Technology

The FinImpulse API follows [**REST**](https://en.wikipedia.org/wiki/Representational_state_transfer) principles, making it straightforward to integrate and work with. This means:

- Each endpoint represents a specific resource and is accessed using standard **HTTP** methods.
- All requests are stateless: the server does not store any client context between requests, so each request must contain all the information required to process it.
- REST-based APIs are easy to scale and simplify debugging and future integration extensions.

## Data Format

The API can be used from any programming language or platform that supports HTTP requests. All responses are returned in [**JSON**](https://en.wikipedia.org/wiki/JSON) format, providing a consistent and widely supported data structure.

## Rate Limits

Each FinImpulse API endpoint has a defined rate limit (up to 2000 requests per minute), which is included in the following HTTP response headers:

- **X-RateLimit-Limit** — the maximum number of requests allowed per minute for the endpoint;
- **X-RateLimit-Remaining** — the number of requests remaining in the current rate limit window.

For higher rate limits, please contact the FinImpulse support team.
