To interact with the Vector Store REST API, you must first obtain a Qwak Token. This token is used to authenticate your requests.

Obtaining a Qwak Token

Generate a new Qwak Token with the following command to obtain a token, valid for 24 hours:

curl --request POST 'https://grpc.qwak.ai/api/v1/authentication/qwak-api-key' \
     --header 'Content-Type: application/json' \
     --data '{"qwakApiKey": "<QWAK_API_KEY>"}'

Export your Qwak Token as an environment variable in your terminal:
```
export QWAK_TOKEN="YOUR_GENERATED_QWAK_TOKEN"
```

Making a Request

Use the following curl command template to send requests to the Vector Store. Replace <your-environment> with the name of your account, which can be found in the bottom left corner of the Qwak Dashboard, and <your operation payload as JSON> with the JSON payload of your operation as in the references below.

curl --location --request POST 'https://grpc.<your-environment>.qwak.ai/api/v1/vectors/upsert' \
--header 'Content-Type: application/json' \
--header "Authorization: Bearer $QWAK_TOKEN" \
--data '<your operation payload as JSON>'

URL Structure

Base URL: https://grpc.<your-environment>.qwak.ai, replace <your-environment> with your specific account name.

Required Headers

Content-Type: Should always be application/json
Authorization: Use the bearer token format: Bearer <your_qwak_token>.
Ensure the header is enclosed in double quotes (") when passing the QWAK_TOKEN as an environment variable.

📘
Before executing the curl command, ensure the QWAK_TOKEN environment variable is correctly set in your terminal with the value of your generated Qwak Token. This step is crucial for authenticating your requests to the Vector Store.
