# InfluxDB v2 API client libraries

#### Use InfluxDB 3 clients to query

InfluxDB 3 supports [compatibility endpoints for *writing data*](/influxdb3/core/write-data/compatibility-apis/) using InfluxDB v2 and v1 tools. However, the `/api/v2/query` API endpoint and associated tooling, such as InfluxDB v2 client libraries and the `influx` CLI, *can’t query* stored in InfluxDB 3 Core.

[InfluxDB 3 client libraries](/influxdb3/core/reference/client-libraries/v3/) are available that integrate with your code to write and query data stored in InfluxDB 3 Core.

InfluxDB 3 supports many different tools for [**writing**](/influxdb3/core/write-data/) and [**querying**](/influxdb3/core/query-data/) data. [**Compare tools you can use**](/influxdb3/core/get-started/#tools-to-use) to interact with InfluxDB 3 Core.

## Client libraries for InfluxDB 2.x and 1.8+

InfluxDB client libraries are language-specific tools that integrate with InfluxDB APIs. InfluxDB v2 client libraries use InfluxDB `/api/v2` endpoints and work with [InfluxDB 2.x API compatibility endpoints](/influxdb/v1/api/buckets-v2-compatible/).

Functionality varies among client libraries. InfluxDB client libraries are maintained by the InfluxDB community. For specifics about a client library, see the library’s GitHub repository.
