# Authentication

Every request must include a valid API key. Requests without one, or with an invalid key, return `HTTP 401 Unauthorized`.

## Your API key

Your API key is provisioned by your Cover Genius CSE. You receive separate keys for staging and production. **Do not use your production key while testing**.

Your API key is sent in the `X_API_KEY` header of your request.

```shellscript
curl --location 'https://api-staging.rentalcover.com/insurances/quote' \
--header 'Content-Type: application/json' \
--header 'x-api-key: XXXXXXXXXXXXXXXXXXXXXXXXXX' \
--data-raw '
{
    "FromDate": "2027-08-01 23:59:59",
    "ToDate": "2027-08-01 23:59:59",
    "DestinationCountry": "GB",
    "CustomerAge": 52,
    "FirstName": "John",
    "LastName": "Doe",
    "Email": "andy.t+testbooking@covergenius.com",
    "Country": "FR",
    "LanguageCode": "fr",
    "Currency": "GBP"
}
```

## Security requirements

* Use HTTPS for all requests. HTTP calls fail in production.
* Store your API key in an environment variable or secrets manager. Never hard-code it.
* Do not expose your API key in client-side JavaScript, public repositories, or logs.
* Contact your CSE immediately if you believe your key has been compromised.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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, and the optional `goal` query parameter:

```
GET https://partner-docs.covergenius.com/rentalcover/authentication.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
