# Credit usage

# Introduction

A credit will be charged when fetching a company for the first time. You'll then be able to get all company details for free in the next 30 days.

The endpoints for which a credit will be charged the first time you access the company are `Details`, `Financials`, `Relationships`, `Lookalikes`, `Contacts`. All other endpoints are free of use, like `Search` and list endpoints.

## Enriching contacts

You will only be charged for enrichments when data is **available**.<br /> If no data is available, no credits will be charged.

### Emails

A credit will be charged when enriching a contact with an email address.<br /> This is only applicable for the `Contact Details` endpoint.

### Mobile phone numbers

* **2 credits** will be charged when enriching a contact with a mobile phone number, **if the API user does not have a connected Prospeo account**.
* **1 credit** will be charged if the **API user has a connected Prospeo account**.

## Response header

The response header will contain the following fields:

* `X-Bizzy-Credits-Balance`: Your remaining credit balance
* `X-Bizzy-Credits-Charged`: The number of credits charged for this request
