API Credential Library

Suitable for scenarios where you only have Base URL + API Key without a site account. Save common API keys in one place for quick copying, API verification, model lookup, and balance/usage checks without first creating a full site account.

Suitable Scenarios

• You only have the Base URL and API Key provided by a third-party platform, but no corresponding site console account.
• You want to centrally store frequently used interface configurations to avoid repeatedly copying them between multiple clients or CLI tools.
• You need to verify if a key is valid and compatible with the CLI before deciding to import it into downstream tools.
• You want to use the same interface configuration directly for model viewing, interface verification, or export flows.

Feature Overview

• Credential Library Management: Store name, Base URL, API key, tags, and notes without relying on a site account.
• Search and Filter: Supports filtering by name, Base URL, tags, notes, and API type.
• Health and Usage Overview: View balance, today's usage, today's requests, available models, last refresh time, and health status.
• Interface Verification: Supports verifying API availability and separately testing CLI compatibility.
• Model Integration: Directly open the current credentials in the model list to view the model catalog and verification results.
• Quick Export: Supports exporting to CherryStudio, CC Switch, Kilo Code, CLIProxyAPI, Claude Code Router, and self-hosted sites with current configurations.

Access Method

1. Open the plugin settings page.
2. Navigate to API Credential Library in the left-hand menu.
3. Click Save API key in the upper right corner.

If you have already obtained a key for an upstream site in Key Management, you can also verify or organize it there before saving it to the API Credential Library for easier later use.

How to Add Credentials

Basic Fields

API Type

Currently supports classification and verification by API type. Common types include:

• OpenAI Compatible
• OpenAI
• Anthropic
• Google

If you temporarily use another API type for verification, the interface will clearly indicate that this is only a temporary override for this verification and will not change the saved credential type.

Balance and Usage Overview

Each credential card can display a lightweight telemetry overview, with common metrics including:

• Balance
• Today's Usage
• Today's Requests
• Today's Tokens
• Available Models
• Last Refresh Time
• Health Status and Last Error

Query Method

You can choose the balance/usage query method for each credential:

• Auto-detect: Attempts compatible methods in a built-in order.
• NewAPI Token: Suitable for querying token usage compatible with New API.
• OpenAI Billing: Suitable for standard OpenAI Billing queries.
• Sub2API: Suitable for Sub2API-style interfaces.
• Custom Read-only Endpoint: Suitable for sites with custom read-only query endpoints.
• Disabled: Does not query balance and usage, only retains the credential itself.

Detailed Telemetry Metrics

After enabling telemetry, the extension will attempt to retrieve the following metrics:

• Real-time Balance
• Today Cost
• Today Requests
• Today Prompt/Completion Tokens
• Total Used/Total Granted/Total Available Quota
• Expiration Time

Custom Read-only Query

If the automatic method is not compatible with the current site, you can use a custom read-only query:

1. Select Custom Read-only Endpoint.
2. Enter the query address (must be from the same origin as the Base URL, supports root-relative paths like /usage).
3. Configure Field Mapping: Supports configuring JSON Paths for all telemetry metrics mentioned above.
   • JSON Path uses a dot-separated format, e.g., data.today_total_tokens.
   • The extension will automatically parse and convert it into a unified display format.

Stability and Rate Limiting

To protect your account from being judged as abnormal by upstream sites, All API Hub has a built-in Smart Request Limiter:

• Concurrency Control: Defaults to limiting the number of concurrent requests to a single site to 2.
• Rate Control: Limits the request rate to a single site to approximately 18 times per minute (supports small bursts).
• Auto-Queueing: When refreshing multiple accounts or performing batch verification, requests exceeding the limit will automatically enter a queue to avoid triggering 429 Too Many Requests errors.

💡 Note: This limit is primarily for refresh and verification actions in the extension background and does not affect the performance of direct interface calls via other tools (such as CherryStudio).

Common Operations

1. Verify Interface

Click Verify Interface on the card to confirm:

• If the current key can still be used.
• If the model list can be fetched.
• If the response conforms to the expected API type.

This is useful when changing keys, switching networks, or troubleshooting "client cannot connect, but the site seems alive."

2. Verify CLI Compatibility

Click Verify CLI Compatibility to separately test:

• If the current interface is suitable for CLI tools.
• If the model ID can be used in CLI scenarios.
• If there are compatibility differences such as "web can call, but CLI cannot."

3. Open in Model Management

After clicking Open in Model Management, the model list page will directly use the current API credential as the data source. This allows you to view the model catalog and verify model availability without first creating a site account.

4. Quick Export

Supports direct export from a single credential to:

• CherryStudio
• CC Switch
• Kilo Code
• CLIProxyAPI
• Claude Code Router
• Current self-hosted sites

If your primary goal is to "manage a batch of upstream interface configurations and then distribute them to multiple downstream tools," the API Credential Library will be more direct than full account management.

Usage Recommendations

• Name with Purpose: For example, "OpenAI Read-only Test Key" or "Company Relay Station Claude Specific Key" for clearer filtering later.
• Use Tags as Groups: For example, Work, Personal, Production, Test, Temporary.
• Verify Before Export: This prevents batch importing invalid keys into multiple clients.
• Record Limitations in Notes: For example, "Only supports Anthropic," "Balance display is inaccurate," "Internal network only."
