The `/query` 1.x compatibility endpoint queries InfluxDB {{< current-version >}} using **InfluxQL**.
Use the `GET` request method to query data from the `/query` endpoint.

<pre>
<span class="api get">GET</span> http://localhost:8086/query
</pre>

The `/query` compatibility endpoint uses the **database** and **retention policy**
specified in the query request to map the request to an InfluxDB bucket.
For more information, see [Database and retention policy mapping](/influxdb/v2/reference/api/influxdb-1x/dbrp).

{{% cloud-only %}}

{{% note %}}
If you have an existing bucket that doesn't follow the **database/retention-policy** naming convention,
you **must** [manually create a database and retention policy mapping](/influxdb/v2/query-data/influxql/dbrp/#create-dbrp-mappings)
to query that bucket with the `/query` compatibility API.

## Authentication

Use one of the following authentication methods:
* **token authentication**
* **basic authentication with username and password**
* **query string authentication with username and password**

_For more information, see [Authentication](/influxdb/v2/reference/api/influxdb-1x/#authentication)._

## Query string parameters

### u
(Optional) The 1.x **username** to authenticate the request.
_See [query string authentication](/influxdb/v2/reference/api/influxdb-1x/#query-string-authentication)._

### p
(Optional) The 1.x **password** to authenticate the request.
_See [query string authentication](/influxdb/v2/reference/api/influxdb-1x/#query-string-authentication)._

### db
({{< req >}}) The **database** to query data from.
This is mapped to an InfluxDB [bucket](/influxdb/v2/reference/glossary/#bucket).
_See [Database and retention policy mapping](/influxdb/v2/reference/api/influxdb-1x/dbrp/)._

### rp
The **retention policy** to query data from.
This is mapped to an InfluxDB [bucket](/influxdb/v2/reference/glossary/#bucket).
_See [Database and retention policy mapping](/influxdb/v2/reference/api/influxdb-1x/dbrp/)._

### q
({{< req >}}) The **InfluxQL** query to execute.
To execute multiple queries, delimit queries with a semicolon (`;`).

### epoch
Return results with [Unix timestamps](/influxdb/v2/reference/glossary/#unix-timestamp)
(also known as epoch timestamps) in the specified precision instead of
[RFC3339 timestamps](/influxdb/v2/reference/glossary/#rfc3339-timestamp) with nanosecond precision.
The following precisions are available:

- `ns` - nanoseconds
- `u` or `µ` - microseconds
- `ms` - milliseconds
- `s` - seconds
- `m` - minutes
- `h` - hours
