## Pricing


For pricing, please refer to the [Amazon Bedrock Pricing](https://aws.amazon.com/bedrock/pricing/) page.

## Programmatic Access


Use the following model IDs and endpoint URLs to access this model programmatically. For more information about the available APIs and endpoints, see [APIs supported](https://docs.aws.amazon.com/bedrock/latest/userguide/apis.html) and [Endpoints supported](https://docs.aws.amazon.com/bedrock/latest/userguide/endpoints.html).


| **Endpoint** | **Model ID** | **In-Region endpoint URL** | **Geo inference ID** | **Global inference ID** | 
| --- | --- | --- | --- | --- | 
| bedrock-runtime | writer.palmyra-x5-v1:0 | https://bedrock-runtime.\$1region\$1.amazonaws.com | us.writer.palmyra-x5-v1:0 | Not supported | 

*For example, if region is us-east-1 (N. Virginia), then the bedrock-runtime endpoint URL will be "https://bedrock-runtime.us-east-1.amazonaws.com" and for bedrock-mantle will be "https://bedrock-mantle.us-east-1.api.aws/v1".*

## Service Tiers


Amazon Bedrock offers multiple service tiers to match your workload requirements. **Standard** provides pay-per-token access with no commitment. **Priority** offers higher throughput with a time-based commitment. **Flex** provides lower-cost access for flexible, non-time-sensitive workloads. **Reserved** provides dedicated throughput with a term commitment for predictable workloads. For more information, see [service tiers](https://docs.aws.amazon.com/bedrock/latest/userguide/service-tiers-inference.html).


| **Standard** | **Priority** | **Flex** | **Reserved** | 
| --- | --- | --- | --- | 
| ![\[Yes\]](http://docs.aws.amazon.com/bedrock/latest/userguide/images/icons/icon-yes.png) | ![\[No\]](http://docs.aws.amazon.com/bedrock/latest/userguide/images/icons/icon-no.png) | ![\[No\]](http://docs.aws.amazon.com/bedrock/latest/userguide/images/icons/icon-no.png) | ![\[No\]](http://docs.aws.amazon.com/bedrock/latest/userguide/images/icons/icon-no.png) | 

## Regional Availability


***Regional availability at a glance***

Bedrock offers three inference options: **In-Region** keeps requests within a single Region for strict compliance, **Geo Cross-Region** routes across Regions within a geography (US, EU, etc.) for higher throughput while respecting data residency, and **Global Cross-Region** routes anywhere worldwide for maximum throughput when there are no residency constraints. Refer to the [Regional availability](models-region-compatibility.md) page for more details.

## Sample Code


**Step 1 - AWS Account:** If you have an AWS account already, skip this step. If you are new to AWS, sign up for an [AWS account](https://portal.aws.amazon.com/billing/signup).

**Step 2 - API key:** Go to the [Amazon Bedrock console](https://console.aws.amazon.com/bedrock/home#/api-keys/long-term/create) and generate a long-term API key.

**Step 3 - Get the SDK:** To use this getting started guide, you must have Python already installed. Then install the relevant software depending on the APIs you are using.

```
pip install boto3
```

**Step 4 - Set environment variables:** Configure your environment to use the API key for authentication.

```
AWS_BEARER_TOKEN_BEDROCK="<provide your Bedrock API key>"
```

**Step 5 - Run your first inference request:** Save the file as `bedrock-first-request.py`
