# Passu API

> Public API for sectors, companies, events, metrics, and analyses.

## Overview

The Passu API is a read-only HTTP API for retrieving:

* sectors
* companies
* events
* metrics
* analyses

The API is served from `https://api.passu.ai` and versioned under `/v1`.

## Authentication

Access is authenticated with Passu-managed API keys.

1. An admin creates an API key in the Passu dashboard.
2. The key owner receives a `client_id` and `client_secret`.
3. Your server exchanges those for a bearer token with `POST /v1/auth/token`.
4. Send the bearer token on every request with `Authorization: Bearer <token>`.

See [Authentication](authentication) for the full flow.

## API reference

The API reference is generated directly from the live OpenAPI document served by the API.
