Application Scenarios

• Guide customers to invoke MaaS models (text generation, deep thinking, image understanding, image generation, video generation, embedding, rerank)
• Help customers select appropriate models based on their use case
• Provide API calling examples in multiple programming languages
• Guide API Key creation and management
• Provide development tool integration guidance (OpenClaw, OpenCode, Claude Code, Dify, Cherry Studio, Cursor, Cline, RAGFlow, Deep Research)
• Explain differences between MaaS Standard API, OpenAI Compatible API, and Anthropic Compatible API

User Scenario Examples

1. Basic invocation: "How do I call DeepSeek-V3.2 model?"
2. Model selection: "Which model should I use for code generation?"
3. API Key management: "How do I create an API Key for MaaS?"
4. Code examples: "Give me Python code to call GLM-5"
5. Development tool integration: "How do I use MaaS with Cursor?"
6. Deep thinking: "How do I enable deep thinking mode?"

2. Prerequisites

Account and Authorization

Before using MaaS, the following prerequisites must be met:

1. Registered Huawei Cloud account with real-name authentication. See: Register Huawei Account and Activate Huawei Cloud

2. ModelArts delegation authorization completed. This is a necessary prerequisite for using MaaS service. For detailed steps, see references/iam-policies.md.

3. Preset service activated: Navigate to "Model Inference > Online Inference > Preset Services" in MaaS console, and click "Activate Service" for the target model.

4. API Key obtained: Navigate to "Management & Statistics > API Key Management" in MaaS console to create or manage API Keys.

API Key Management

Cannot create API Key for the user, please guide the user to create it themselves:

API Key Creation URL: Log in to MaaS console → Management & Statistics → API Key Management → Create API Key

⚠️ Important: API Key will only be displayed once after creation. Please copy and save it promptly. If the API Key is lost, please create a new one.

API Key Notes:

• Each account can create up to 30 API Keys
• API Keys are region-specific and cannot be used across regions
• API Key takes a few minutes to take effect after creation
• API Key tags cannot be modified after creation

IAM Permission Requirements

This skill requires the following IAM permissions:

• ModelArts CommonOperations - Use ModelArts service (recommended for sub-users)
• OBS OperateAccess - Object storage service access
• SWR OperateAccess - Container registry access
• CES FullAccess - Cloud Eye monitoring
• SMN FullAccess - Message notification service

Detailed permission policies and configuration instructions: references/iam-policies.md

Permission Failure Handling

When any operation encounters a permission error, MUST follow this process:

1. Identify permission error - Check if error message contains keywords like "Access Restricted", "Insufficient Permissions", "Missing Permissions"
2. Refer to permission documentation - Immediately guide user to view references/iam-policies.md
3. Display permission list - Show user the required permission list
4. Guide permission configuration - Guide user to configure permissions in Huawei Cloud IAM console or ModelArts Permission Management
5. Pause and wait for confirmation - Wait for user to confirm permission configuration is complete

3. Core Workflow/Process

Step 1: Determine Customer Needs

• Ask: "What type of model do you want to invoke?"

  • Text Generation/Dialogue, Deep Thinking, Image Understanding, Image Generation, Video Generation, Text Embedding, Rerank

• If customer has not specified a specific model:

  • Option A: Ask about use case/scenario, recommend appropriate models (see Recommended Models table in Section 4)
  • Option B: List all available models for customer to choose (see references/model-list.md)

• When listing models, include model information: model parameter, capabilities, context length, supported features, etc.

Step 2: Provide Invocation Information

After customer selects a specific model, provide:

1. Invocation URL - Based on model type and customer preference
   • For large language models, if customer hasn't specified preference, provide all supported API formats (MaaS Standard V2, OpenAI Compatible, Anthropic Compatible) and explain differences
   • Note: Not all models support all API interface types, must check model's supported API types in references/api-interfaces.md
2. Model Name - The model parameter value (e.g., deepseek-v3.2)
3. API Key Creation URL - MaaS Console → Management & Statistics → API Key Management
4. Code Examples - See references/code-examples.md and references/code-examples-advanced.md

Step 3: Provide Code Examples

Provide code examples based on customer's preferred programming language:

• Python (requests library)
• Curl
• OpenAI Python SDK
• Java (JDK 15+)

See references/code-examples.md for text generation/deep thinking/streaming/multi-turn examples. See references/code-examples-advanced.md for image understanding/image generation/video generation/embedding/rerank examples.

Step 4: Ask About Additional Needs

• Ask: "Do you need guidance on integrating with other development tools?"
  • If yes, list available tools for customer to choose:
    • OpenClaw, OpenCode, Claude Code, Dify, Cherry Studio, Cursor, Cline, RAGFlow, Deep Research
  • See references/dev-tools-integration.md for specific integration guidance

Step 5: Pricing Reminder

Remind the user that MaaS supports the following three billing methods:

Method 1: Pay-per-use

• Remind the user: "For specific pricing, please refer to MaaS pricing details: https://www.huaweicloud.com/pricing/calculator.html#/maas"

Method 2: Package Plan Billing

Package plans are only supported by some models (for specific supported models, please refer to the purchase link). Users can purchase a package plan on the Huawei Cloud website first, and when invoking MaaS preset services, billing will be based on the actual number of Tokens used.

• Package plan purchase link: https://activity.huaweicloud.com/openclaw.html
• Specific prices, promotional information, and constraints are subject to the activity page and purchase page
• Usage scope: Package plans only support deducting input Tokens and output Tokens consumed by online experience or API invocation of DeepSeek models using the "Model Inference > Online Inference > Preset Services" or "Model Inference > Online Inference > Custom Access Points" feature
• Billing rules: To ensure normal business operation, billing will prioritize the package plan quota. Excess usage will be automatically charged at the normal price based on the Token usage of the model. To stop billing, please stop invoking the service promptly. No charges will be incurred if the service is not used.
• Usage region: Package plans are bound to the region selected at purchase and can only be used in that region
• Package plan deduction order: For multiple package plans of the same model, billing will deduct in the following order: earliest expiration time > earliest effective time > earliest creation time
• Unsubscription policy: Purchased package plans cannot be unsubscribed. Please confirm before purchasing.

Method 3: MaaS Token Plan Billing

Token Plan is a subscription service designed specifically for developers and is only supported by some models. Users can go to the MaaS console "Management & Statistics > Subscription Management" page to purchase a Token Plan, and then use it in AI tools such as Claude Code and OpenClaw.

• Token Plan details and supported models: Please go to the MaaS console "Management & Statistics > Subscription Management" page to view, or refer to references/token-plan.md
• Be sure to use models supported by Token Plan and the dedicated Base URL. If the specified dedicated Base URL is not used, the Token Plan quota cannot be used, and additional API request charges may be incurred.
• Purchased plans cannot be unsubscribed

Important: Do not directly tell the user the pricing, and do not tell the user which models support package plan and Token Plan billing. You can provide the relevant links directly and let the user check the links.

Step 6: Output Invocation Guide

Organize and output invocation information to customer, including: URL, model name, API Key, and code examples. Use the template format in references/invocation-output-template.md.

7. Verification Method

Skill verification and testing methods: references/verification-method.md

1. Prerequisites verification: Ensure account, authorization, preset service, and API Key are ready
2. API connectivity verification: Test basic API call with Curl or Python
3. Feature verification: Test deep thinking, streaming, multi-turn conversation if applicable
4. Integration verification: Test development tool connection if applicable

8. Best Practices

Please refer to references/best-practices.md for best practices.

Model Selection Best Practices

1. Choose the latest model version - Newer models have significantly improved capabilities
2. Choose models with corresponding capabilities - Check capability support for your needed features
3. Consider cost-effectiveness - Use lighter models for simple tasks

API Invocation Best Practices

1. MaaS is stateless - Include all conversation history in each request for multi-turn conversations
2. Use streaming for interactive applications - Improves user experience with incremental output
3. Set max_tokens - Control costs by limiting output length
4. Send requests evenly - Avoid burst requests to prevent rate limiting

API Key Management Best Practices

1. Save immediately - API Key cannot be retrieved after creation
2. Use separate keys - Create different API Keys for different applications
3. Region awareness - API Keys are region-specific

10. Notes

Security Tips

• API Key security: Never expose API Key in code, logs, or conversations
• Principle of least privilege: Grant only necessary IAM permissions
• Regular rotation: Regularly delete old API Keys and create new ones
• Data privacy: MaaS does not retain user data for model training

Limitations

• Regional restrictions: All MaaS model services only support 西南-贵阳一 region
• API Key limits: Max 30 API Keys per account, region-specific, takes minutes to take effect
• Rate limiting: Different models have different TPM/RPM limits
• API interface support: Not all models support all API interface types (V2, OpenAI, Anthropic, V1)
• Preset service: Cannot be deactivated once activated (no charges when not used)

Known Issues

1. API Key activation delay: API Key takes a few minutes to become effective after creation
2. DeepSeek-V3.1 constraints: Function Call and deep thinking are not compatible; deep thinking doesn't support prefix continuation
3. Video generation async: Video generation is asynchronous, task data retained for 24 hours only
4. Image size limits: Base64-encoded images must be < 10MB
5. MaaS Standard API V1: No longer evolving, recommend using V2

Troubleshooting

Common errors and solutions:

1. 401 Authentication failed: Check API Key is correct and has taken effect
2. 404 Model not found: Check model parameter name is correct
3. 429 Rate limit exceeded: Reduce request frequency, implement retry with backoff
4. ModelArts.81101 Too Many Requests: Rate limited, wait and retry
5. Service frozen: Account may be in arrears, recharge to unfreeze
