              this License, without any additional terms or conditions.
              Notwithstanding the above, nothing herein shall supersede or modify
              the terms of any separate license agreement you may have executed
              with Licensor regarding such Contributions.
        
           6. Trademarks. This License does not grant permission to use the trade
              names, trademarks, service marks, or product names of the Licensor,
              except as required for reasonable and customary use in describing the
              origin of the Work and reproducing the content of the NOTICE file.
        
           7. Disclaimer of Warranty. Unless required by applicable law or
              agreed to in writing, Licensor provides the Work (and each
              Contributor provides its Contributions) on an "AS IS" BASIS,
              WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
              implied, including, without limitation, any warranties or conditions
              of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
              PARTICULAR PURPOSE. You are solely responsible for determining the
              appropriateness of using or redistributing the Work and assume any
              risks associated with Your exercise of permissions under this License.
        
           8. Limitation of Liability. In no event and under no legal theory,
              whether in tort (including negligence), contract, or otherwise,
              unless required by applicable law (such as deliberate and grossly
              negligent acts) or agreed to in writing, shall any Contributor be
              liable to You for damages, including any direct, indirect, special,
              incidental, or consequential damages of any character arising as a
              result of this License or out of the use or inability to use the
              Work (including but not limited to damages for loss of goodwill,
              work stoppage, computer failure or malfunction, or any and all
              other commercial damages or losses), even if such Contributor
              has been advised of the possibility of such damages.
        
           9. Accepting Warranty or Additional Liability. While redistributing
              the Work or Derivative Works thereof, You may choose to offer,

              or other liability obligations and/or rights consistent with this
              License. However, in accepting such obligations, You may act only
              on Your own behalf and on Your sole responsibility, not on behalf

              defend, and hold each Contributor harmless for any liability
              incurred by, or claims asserted against, such Contributor by reason
              of your accepting any such warranty or additional liability.
        
           END OF TERMS AND CONDITIONS

# KS3 Vectors Embed CLI

KS3 Vectors Embed CLI is a command-line tool for KingsoftCloud KS3 vector buckets. It vectorizes text, images, and videos into a KS3 vector index and performs similarity search through simple commands.

## Supported Commands

**ks3-vectors-embed put**: Embed text, file content, or KS3 objects and store them as vectors in a KS3 vector index.
You can create and ingest vector embeddings into a KS3 vector index using a single put command. You specify the data input you want to create an embedding for, an embedding model ID, your KS3 vector bucket name, and KS3 vector index name. The command supports several input formats including text data, a local text or image file, a KS3 text or image object or prefix. The command generates embeddings using the dimensions configured in your KS3 vector index properties. If you are ingesting embeddings for several objects in a KS3 prefix or local file path, it automatically uses batch processes to maximize throughput.

**Note**: Each file is processed as a single embedding. Document chunking is not currently supported.

**ks3-vectors-embed query**: Embed a query input and search for similar vectors in a KS3 vector index.
You can perform similarity queries for vector embeddings in your KS3 vector index using a single query command. You specify your query input, an embedding model ID, the vector bucket name, and vector index name. The command accepts several types of query inputs like a text string, an image file, or a single KS3 text or image object. The command generates embeddings for your query using the input embeddings model and then performs a similarity search to find the most relevant matches. You can control the number of results returned, apply metadata filters to narrow your search, and choose whether to include similarity distance in the results for comprehensive analysis.

## Installation and Configuration

### Prerequisites

Make sure the following are ready before using this tool:

- Python 3.9 or higher.
- KS3 service enabled, with AccessKey ID and AccessKey Secret obtained.
- KingsoftCloud Starflow Platform enabled, with an API Key obtained.
- A vector bucket and a vector index created.

> **Important**: The vector index dimension must match the embedding model's output dimension, otherwise writes will fail.

### Quick Install (Recommended)

```bash
pip install ks3-vectors-embed-cli
```

### Development Install

```bash
git clone https://github.com/ks3sdklib/ks3-vectors-embed-cli.git
cd ks3-vectors-embed-cli
pip install -e .
```

### Verify installation

```bash
ks3-vectors-embed --version
# Output: ks3-vectors-embed, version 0.1.0
```

### Configure credentials

Configure credentials as environment variables. The CLI reads them automatically, so you don't need to pass them in every command.

```bash
# KS3 access key (shared by object reads and vector buckets, required)
export KS3_ACCESS_KEY_ID="AK"
export KS3_ACCESS_KEY_SECRET="SK"

# Object storage and vector bucket endpoints (optional, defaults below)
export KS3_ENDPOINT="ks3-cn-beijing.ksyuncs.com"
export KS3_VECTORS_ENDPOINT="ks3vectors-cn-beijing.ksyuncs.com"

# Embedding service (API Key required, endpoint optional, defaults below)
export KSC_API_KEY="APIKey"
export KSC_BASE_URL="https://kspmas.ksyun.com/v1/"
```

Environment variables:

| Variable | Description | Required |
|---|---|---|
| `KS3_ACCESS_KEY_ID` | KS3 access key ID, shared by object reads and vector buckets | Yes |
| `KS3_ACCESS_KEY_SECRET` | KS3 access key secret, shared by object reads and vector buckets | Yes |
| `KS3_SECURITY_TOKEN` | Temporary security token, only for STS temporary credentials | No |
| `KS3_ENDPOINT` | Object storage endpoint, default `ks3-cn-beijing.ksyuncs.com` | No |
| `KS3_VECTORS_ENDPOINT` | Vector bucket endpoint, default `ks3vectors-cn-beijing.ksyuncs.com` | No |
| `KSC_API_KEY` | Embedding service API Key | Yes |
| `KSC_BASE_URL` | Embedding service endpoint, default `https://kspmas.ksyun.com/v1/` | No |
