CC-Switch Guide for Daya

CC-Switch is an open-source, cross-platform desktop tool designed to centrally manage configuration for AI coding assistants. It supports managing provider settings for four major coding tools—Claude Code, Codex, Gemini CLI, and OpenCode—so you can switch API providers in one click through a visual interface, without manually editing environment variables or JSON files.

Compatibility Notes

CC-Switch can manage four coding tools: Claude Code, Codex, Gemini CLI, and OpenCode. By configuring Daya as a provider in CC-Switch, you can:

Visual management: No more manual edits to environment variables and config files—complete everything in a GUI
One-click switching: Switch instantly between Daya and other providers without restarting your terminal
Unified configuration: Configure Daya once and sync it to multiple coding tools
Automatic failover: Automatically switch to a backup provider if the primary provider is unavailable
Request monitoring: View request logs and usage statistics in real time

CC-Switch supports both the Anthropic protocol and the OpenAI protocol, both of which integrate seamlessly with Daya.

Get a Daya API Key

Before configuring CC-Switch, you’ll need a Daya API Key. Daya offers two billing options—choose based on your use case:

Subscription API Key (Recommended)Pay-as-you-go API Key

text

✅ Use cases: personal development, learning/exploration, vibe coding
✅ Features: fixed monthly fee, predictable cost, 5–10x price leverage
✅ API Key format: sk-ss-v1-xxx

How to get it:
1. Visit the subscription management page: https://api.dayaai.com/subscriptions
2. Choose a plan (Pro $20/month, Max $100/month, Ultra $200/month)
3. After subscribing, create a subscription API key on the page

For details, see: Subscription Plan Guide
📚 https://api.dayaai.com/docs/guide/subscription.html

text

✅ Use cases: production environments, commercial products, enterprise apps
✅ Features: no rate limits, production-grade stability, billed by actual usage
✅ API Key format: sk-ai-v1-xxx

How to get it:
1. Visit the pay-as-you-go page: https://api.dayaai.com/console/topup
2. Top up your account (top-ups automatically include 20% bonus credits)
3. Create an API key in the "Pay As You Go API Keys" section

For details, see: Pay-as-you-go Guide
📚 https://api.dayaai.com/docs/guide/pay-as-you-go.html

💡 Important: Choose the Correct API Key Type

Personal development/learning → use a Subscription API Key (sk-ss-v1-xxx) for lower, better value cost
Production/commercial projects → use a Pay-as-you-go API Key (sk-ai-v1-xxx) for higher stability and no limits

Subscription keys are not allowed for production use. Violations may result in account restrictions.

Configure the Daya Provider

Step 1: Open Provider Management

cc-switch

After launching CC-Switch, select the coding tool you want to configure in the top navigation bar (e.g., Claude Code) to open the provider management page.

💡 First Launch

On first launch, CC-Switch automatically imports your existing local Claude Code / Codex / Gemini CLI / OpenCode configuration as the default provider—no manual migration required.

Step 2: Add the Daya Provider

cc-switch

Click Add Provider and fill in the following configuration:

Claude Code Configuration (Anthropic Protocol)

Setting	Value	Notes
Provider Name	`Daya`	Custom name for easy identity
Base URL	`https://api.dayaai.com/api/anthropic`	Daya Anthropic-compatible endpoint
API Key	`sk-ss-v1-xxx` or `sk-ai-v1-xxx`	Your Daya API key

Configure Model Mapping to map Claude Code’s three speed tiers to models on Daya:

Tier	Recommended Model	Notes
Haiku (Fast)	`anthropic/claude-haiku-4.5`	Fast completions, simple tasks
Sonnet (Balanced)	`anthropic/claude-sonnet-4.5`	Recommended for daily development; best value
Opus (Powerful)	`anthropic/claude-opus-4.5`	Complex architecture, large refactors

💡 Flexible Model Selection

With Daya, you can map not only to Claude models, but also to models from other providers. For example:

Haiku tier → volcengine/doubao-seed-code (Doubao coding model)
Sonnet tier → openai/gpt-5.2 (GPT-5.2)
Opus tier → google/gemini-3-pro-preview (Gemini 3 Pro)

For more models that support the Anthropic protocol, see the Daya model list.

    "baseURL": "https://api.dayaai.com/api/v1"
  }
}

cc-switch Copy and paste the configuration above into OpenCode’s config file, then save to complete setup.

🔑 Important: Replace the API Key

Make sure to replace <DAYA_API_KEY> in the configuration with your real Daya API key:

Subscription API Key (Recommended for personal development)

Format: sk-ss-v1-xxx
Get it here: Subscription management page
Detailed guide: Subscription plan docs

Pay-as-you-go API Key (Production environments)

Format: sk-ai-v1-xxx
Get it here: Pay-as-you-go page
Detailed guide: Pay-as-you-go docs

Step 3: Switch to the Daya Provider

After adding it, click the toggle button next to Daya in the provider list to route the current coding tool’s requests through Daya.

Hot Switching Supported

CC-Switch supports hot-switching providers—no need to restart your terminal or coding tool. After switching, new requests are immediately forwarded via Daya, and existing conversation context remains unaffected.

If you use multiple coding tools, CC-Switch can sync the same provider configuration across all managed apps. This is especially convenient for an API gateway like Daya that supports multiple protocols:

Enable Cross-app sharing (Universal Provider) in the provider settings
Set default model mappings for each app
Save—this provider will automatically sync to Claude Code, Codex, Gemini CLI, and OpenCode

Supported Models

Anthropic Protocol Model Support

Models that support the Anthropic protocol are being adapted in batches. You can filter the currently supported models via the official model list and select the Anthropic Messages protocol.

The OpenAI protocol supports a much broader set of models. You can filter the model list by "OpenAI API Compatible".

Troubleshooting

Common Issues

API Key Error or Authentication Failure

Issue: After configuring the provider, you see that the API key is invalid or unauthorized.

Solution:

Check the API key format:
- Subscription keys should start with sk-ss-v1-
- Pay-as-you-go keys should start with sk-ai-v1-
- Make sure there are no extra spaces or line breaks
Verify the API key is valid:
- Subscription: visit the subscription management page to check subscription status and quota
- Pay-as-you-go: visit the pay-as-you-go page to ensure your balance is sufficient
Confirm the Base URL is correct:
- Claude Code (Anthropic protocol): https://api.dayaai.com/api/anthropic
- Codex / OpenCode (OpenAI protocol): https://api.dayaai.com/api/v1
- Gemini CLI (Vertex AI protocol): https://dayaai.com/api/vertexai :::

macOS Shows “Developer Cannot Be Verified”

Issue: On first launch, macOS shows “Developer cannot be verified”.

Solution:

Because the developer does not yet have Apple Developer signing, macOS may block the app on first run.

Go to System Settings → Privacy & Security
Find the blocked CC-Switch message at the bottom of the page
Click Open Anyway
In the confirmation dialog, click Open

This prompt will not appear on subsequent launches.

Coding Tool Not Responding After Switching Providers

Issue: After switching to Daya in CC-Switch, the coding tool’s requests don’t change.

Solution:

Confirm CC-Switch is running (the system tray icon should be visible)
Check whether the provider for that coding tool has been switched correctly in CC-Switch (the active provider is highlighted)
Trigger a new request in the coding tool and confirm it routes through Daya
If it still doesn’t work, restart the coding tool and test again

Model Does Not Support the Anthropic Protocol

Issue: In Claude Code, a model reports that it doesn’t support the Anthropic protocol.

Solution:

Use the Daya model list and filter by "Anthropic API Compatible" to see currently supported models
Ensure the model ID in model mapping is correct (e.g., anthropic/claude-sonnet-4.5, not claude-sonnet-4.5)
Use a model from the supported list above
