All requests to [Pinecone APIs](/guides/apis-introduction) must contain a valid [API key](/guides/move-to-production-security-overview#api-keys) for the target project.

## Get an API key

[Create a new API key](https://app.pinecone.io/organizations/-/projects/-/keys) in the Pinecone console, or use the connect widget below to generate a key.

Copy your generated key:

```
PINECONE_API_KEY="{{YOUR_API_KEY}}"

# This API key has ReadWrite access to all indexes in your project.
```

## Initialize a client

When using a [Pinecone SDK](/guides/sdks-pinecone-sdks), initialize a client object with your API key and then reuse the authenicated client in subsquent function calls. For example:

:::code-group
```Python Python theme={null}
from pinecone.grpc import PineconeGRPC as Pinecone
from pinecone import ServerlessSpec

pc = Pinecone(api_key='YOUR_API_KEY')

# Creates an index using the API key stored in the client 'pc'.
pc.create_index(
    name="docs-example",
    dimension=1536,
    metric="cosine",
    spec=ServerlessSpec(
        cloud='aws', 
        region='us-east-1'
    ) 
) 
```

```JavaScript JavaScript theme={null}
import { Pinecone } from '@pinecone-database/pinecone';

const pc = new Pinecone({
    apiKey: 'YOUR_API_KEY' 
});

// Creates an index using the API key stored in the client 'pc'.
await pc.createIndex({
    name: 'docs-example',
    dimension: 1536,
    metric: 'cosine',
    spec: { 
        serverless: { 
            cloud: 'aws', 
            region: 'us-east-1' 
        }
    } 
}) 
```

```java Java theme={null}
import io.pinecone.clients.Pinecone;
import org.openapitools.db_control.client.model.IndexModel;
import org.openapitools.db_control.client.model.DeletionProtection;

public class CreateServerlessIndexExample {
    public static void main(String[] args) {
        Pinecone pc = new Pinecone.Builder("YOUR_API_KEY").build();

        // Creates an index using the API key stored in the client 'pc'.
        pc.createServerlessIndex("docs-example", "cosine", 1536, "aws", "us-east-1");
    }
}
```

```go Go theme={null}
package main

import (
    "context"
    "fmt"
    "log"

    "github.com/pinecone-io/go-pinecone/v3/pinecone"
)

func main() {
    ctx := context.Background()

    pc, err := pinecone.NewClient(pinecone.NewClientParams{
        ApiKey: "YOUR_API_KEY",
    })
    if err != nil {
        log.Fatalf("Failed to create Client: %v", err)
    }

	indexName := "docs-example"
	vectorType := "dense"
    dimension := int32(1536)
    metric := pinecone.Cosine
	deletionProtection := pinecone.DeletionProtectionDisabled

    idx, err := pc.CreateServerlessIndex(ctx, &pinecone.CreateServerlessIndexRequest{
        Name:               indexName,
        VectorType:         &vectorType,
        Dimension:          &dimension,
        Metric:             &metric,
        Cloud:              pinecone.Aws,
        Region:             "us-east-1",
        DeletionProtection: &deletionProtection,
    })
    if err != nil {
        log.Fatalf("Failed to create serverless index: %v", err)
    } else {
        fmt.Printf("Successfully created serverless index: %v", idx.Name)
    }
}
```

```shell curl theme={null}
curl -s "https://api.pinecone.io/indexes" \
    -H "Api-Key: YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -H "X-Pinecone-Api-Version: 2025-10" \
    -d '{
        "name":  "docs-example",
        "dimension": 1536,
        "metric": "cosine",
        "spec": {
            "serverless": {
               "cloud":"aws",
               "region": "us-east-1"
            }
        }
    }'
```

## Add headers to an HTTP request

All HTTP requests to Pinecone APIs must contain an `Api-Key` header that specifies a valid [API key](/guides/move-to-production-security-overview#api-keys) and must be encoded as JSON with the `Content-Type: application/json` header. For example:

```shell curl theme={null}
curl https://api.pinecone.io/indexes \
   -H "Content-Type: application/json" \
   -H "Api-Key: $PINECONE_API_KEY" \
  -H "X-Pinecone-Api-Version: 2025-10" \
   -d '{
         "name":  "docs-example",
         "dimension": 1536,
         "metric": "cosine",
         "spec": {
            "serverless": {
               "cloud":"aws",
               "region": "us-east-1"
            }
         }
      }'
```

## Troubleshooting

:::::accordion-group
::::accordion{title="Initialization errors due to outdated SDKs"}
Older versions of Pinecone required you to initialize a client with an `init` method that takes both `api_key` and `environment` parameters, for example:

:::code-group
```python Python theme={null}
# Legacy initialization
import pinecone

pc = pinecone.init(
    api_key="PINECONE_API_KEY",
    environment="PINECONE_ENVIRONMENT"
)
```

```javascript JavaScript theme={null}
// Legacy initialization
import { Pinecone } from '@pinecone-database/pinecone';

const pineconeClient = new PineconeClient();
await pineconeClient.init({
    apiKey: 'PINECONE_API_KEY',
    environment: 'PINECONE_ENVIRONMENT',
});
```
:::

In more recent versions of Pinecone, this has changed. Initialization no longer requires an `init` step, and cloud environment is defined for each index rather than an entire project. Client initialization now only requires an `api_key` parameter, for example:

:::code-group
```python Python theme={null}
# New initialization
from pinecone import Pinecone

pc = Pinecone(api_key="YOUR_API_KEY")
```

```javascript JavaScript theme={null}
// New initialization
import { Pinecone } from '@pinecone-database/pinecone';

const pc = new Pinecone({
    apiKey: 'YOUR_API_KEY' 
});
```
:::

If you are receiving errors about initialization, upgrade your [Pinecone SDK](/guides/sdks-pinecone-sdks) to the latest version, for example:

:::code-group
```shell Python theme={null}
# Upgrade Pinecone SDK
pip install pinecone --upgrade
```

```shell JavaScript theme={null}
# Upgrade Pinecone SDK
npm install @pinecone-database/pinecone@latest
```
:::

Also, note that some third-party tutorials and examples still reference the older initialization method. In such cases, follow the example above and the examples throughout the Pinecone documentation instead.
