# Get coverage command

This command allows you to check our coverage of a network or mobile number without sending a message to that handset. This command should **not** be used before sending each message.

The returned credit charge value indicates the lowest possible credit charge at that point in time (for a single plain-text message). Credit charges may fluctuate (based on the availability of delivery routes and features) and there is no guarantee that all your messages will be charged this value.

```
https://api.clickatell.com/utils/routecoverage?user=xxxx&password=xxxx&api_id=xxxx&msisdn=xxxx
```

{% endcode %}

## 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://help.clickatell.com/developers-api-reference/developers-archive/sms-http-s-api/get-coverage-command.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.
