## Cost Allocation

NetBird forwards the caller's identity to every provider by default — see
[Identity Metadata](/agent-network/providers#identity-metadata) for the general behavior and
how to turn it off. For Bedrock that identity lands in the
[`X-Amzn-Bedrock-Request-Metadata`](https://docs.aws.amazon.com/bedrock/latest/userguide/cost-mgmt-request-metadata.html)
header — the one AWS reads for cost-allocation tags — carrying the caller's **user** and the
**group that authorized the request**:

```
X-Amzn-Bedrock-Request-Metadata: {"user": "user@example.com", "group": "engineering"}
```

Activate the matching **cost-allocation tags** in **AWS Billing and Cost Management → Cost
allocation tags**; Bedrock spend in AWS Cost Explorer can then be broken down by NetBird user
and group. Values are sanitized to Bedrock's accepted character set before they are sent.

The provider's **Mappings** tab shows exactly what NetBird sends:

Qualify the earlier “every request” claim.

This page currently says NetBird forwards identity on every request, but this section introduces a provider-level opt-out. Change the earlier wording to “by default” or otherwise state that forwarding occurs only while the setting is enabled.

The switch appears only for custom (self-hosted) providers and is **off by default**.

### Identity Metadata

By default NetBird stamps the caller's **user** and the **group that authorized the request**
onto each upstream request, so the provider or gateway can attribute usage to the real caller
instead of the shared API key. The exact header or field is provider-specific — see the
provider's [integration guide](/agent-network/integrations) for details (for example, AWS
Bedrock carries it in a header used for [cost-allocation tags](/agent-network/integrations/bedrock#cost-allocation),
and AI gateways receive their own attribution headers).

This is controlled by the **Forward identity metadata** toggle on the provider — **on by
default**, and shown only for providers that support it (first-party APIs such as OpenAI or
Anthropic have no such metadata channel, so the toggle doesn't appear for them). Turn it off
to keep the caller's identity out of the upstream request.

Use one label for this toggle. The body says Forward identity metadata, while the screenshot alt text says Disable identity metadata. Match the UI wording and, if the control is disable-style, make the on/off behavior explicit.
