Provider Keys

Connect an Anthropic, OpenAI, or Amazon Bedrock Provider Key once so Nexus Auto can call closed models without developers sending the key.

• Only account admins can connect, replace, or remove a key.
• A connected key works in every coding harness, including Cursor IDE, the Copilot App, and Claude Desktop.
• Fireworks encrypts keys at rest and never shows them in full again.
• Every Nexus plan includes Provider Keys: Pro, Team, and Enterprise. A developer can also use their own key, saved with nexus auto or sent as a request header.

​

Supported providers

Provider	What you connect
Anthropic	API key
OpenAI	API key
Amazon Bedrock	API key or IAM role, plus a region and model ID for each model

​

Connect a key

1. Open Provider Keys

   Open Provider Keys in Nexus settings.

2. Connect a provider

   Click Connect next to Anthropic, OpenAI, or Amazon Bedrock, and paste your key. For Bedrock, follow Amazon Bedrock Setup.

The provider shows Connected, and requests start using the key within a minute.

​

Replace or remove a key

Open the menu on a connected provider:

• Replace swaps in a new key. Bedrock routes stay in place.
• Remove disconnects the provider. For Bedrock, this also deletes its routes.

​

Manage keys with firectl

firectl is the older way to manage Provider Keys and remains supported for existing scripts. For new setups, use Provider Keys in Nexus settings.

Task	Command
Upload a key	firectl provider-key upload --provider-type PROVIDER --from-file PATH
Make it active	firectl provider-key-binding bind PROVIDER KEY_ID
Check status	firectl provider-key-binding list
Remove	firectl provider-key-binding unbind PROVIDER, then firectl provider-key delete KEY_ID

If you haven’t used firectl before, start with Getting started.

Key behavior and security

• A key sent with a request wins. If a request includes its own provider key, Nexus uses that key instead of the stored one.
• Keys stay private. The dashboard and API show only the provider, state, a masked preview, and dates for each key.
