# Standardize model access without hiding operational evidence

> Engineering teams can centralize authentication and prepaid usage while keeping model selection, evaluation, retries, and data policy under application ownership. The goal is a smaller integration surface and clearer evidence—not an invisible universal abstraction.

## Establish the platform contract

Define which gateway routes the organization supports, which canonical model IDs each workload may call, who owns evaluation, and what telemetry must be retained. KeepRouter exposes compatible OpenAI and Anthropic chat surfaces plus route-specific modality endpoints; your platform layer should make that boundary explicit in its SDK or service template.

## Separate access by responsibility

Issue different keys for teams, services, and environments. Apply allowlists and spend controls that match each workload. Rotate a key without changing the public model ID, and never put an administrator credential in application configuration.

## Release model changes like code

Review the model page and provider release notes, run an evaluation against representative payloads, test streaming and tools, compare measured usage, then promote through configuration. Record the date and exact canonical ID. A rolling provider backend may change behind a stable ID, so retain workload monitoring after release.

## Operational signals and limits

Use request status, latency, token counts, and charge for gateway-level diagnosis. The [status page](/status) covers KeepRouter database, schema, and routing configuration health; it is not a synthetic probe of every upstream model. The application should preserve request IDs, classify retryable failures, and route incidents through its own observability.

## Procurement and data handling

Managed prepaid access reduces the number of direct billing accounts but does not remove governance. Review [security and data handling](/security), disclose intermediaries where required, set internal content rules, and use a direct contract where a workload needs vendor-specific legal or regional terms.

## Frequently asked questions

### Can teams use separate keys?

Yes. Separate keys improve attribution, rotation, allowlisting, and spend boundaries.

### Does the status page probe every model?

No. It reports KeepRouter database, schema, and routing-configuration health without claiming an upstream inference probe.

### How should a model migration be approved?

Review current facts, evaluate representative requests, test protocol features, stage the configuration change, and retain rollback evidence.

### Does managed billing replace vendor governance?

No. Teams still need to assess data, legal, regional, and workload-specific requirements.
