Preamble
Welcome to the Universe API Service Agreement!
This "Universe API Service Agreement" (hereinafter referred to as "this Agreement") is a legal agreement entered into between the operator of the Universe API platform (hereinafter referred to as "we," "us," or "the Service Provider") and you (hereinafter referred to as "the User," "the Developer," or "the Customer") regarding the provision and use of Universe API technical services.
This Agreement, together with the "Universe API User Agreement" and the "Universe API Privacy Policy," constitutes the complete understanding between you and us regarding your use of the Service. In the event of any conflict among these documents, this Agreement shall prevail.
Please read and fully understand all terms of this Agreement before using the Service. By registering, logging in, or using the Service, you acknowledge that you have fully understood and agree to be bound by this Agreement.
1. Service Overview
1.1 Service Content
Universe API provides developers with large language model API services, which primarily include:
| Service Category | Specific Content |
|---|---|
| Model Inference Service | Provides API access to multiple proprietary large language models, including Universe 3.0, Universe 3.0 Pro, Universe 4.5, and others |
| Development Tools | Provides development toolkits including Python SDK, Java SDK, OpenAI-compatible interface, and more |
| Management Platform | Provides a console for account management, API Key management, usage statistics, and billing inquiries |
| Technical Support | Provides technical support channels including online documentation, FAQ knowledge base, and ticket system |
1.2 Service Features
- Pay-As-You-Go: Charges are based on actual Token consumption, with no upfront fees or monthly commitments.
- Elastic Invocation: Flexibly scale your usage based on business needs without applying for resource quotas in advance (subject to rate limits).
- Multi-Model Selection: Offers models at different capability tiers to meet the requirements of various business scenarios.
- Compatible Interfaces: Provides invocation methods compatible with mainstream interface protocols, lowering the barrier to entry for developers.
2. Service Level Agreement (SLA)
2.1 Availability Commitment
We commit that the monthly availability of Universe API services shall be no less than 99.5%.
Availability is calculated as follows:
Monthly Availability = (Total Minutes in Month - Unavailable Minutes in Month) / Total Minutes in Month x 100%
Definition of Unavailable: A minute is considered unavailable if all your API requests within the same minute return 5xx error codes or experience connection timeouts. Service unavailability caused by the following reasons shall not be counted as unavailable time:
- Scheduled system maintenance (announced 24 hours in advance);
- Force majeure events;
- Causes attributable to the User (e.g., expired API Keys, insufficient balance, malformed request formats, etc.);
- Requests exceeding rate limits.
2.2 Service Compensation
If the monthly service availability falls below the committed standard, you may apply for service compensation via a support ticket in the following month:
| Monthly Availability | Compensation Plan |
|---|---|
| 99.0% - 99.5% | Credit 5% of the month's spending to your account balance |
| 95.0% - 99.0% | Credit 15% of the month's spending to your account balance |
| Below 95.0% | Credit 30% of the month's spending to your account balance |
Compensation is issued as account balance and is not withdrawable as cash. Compensation claims must be filed within 30 days of the incident.
2.3 Performance Metrics
| Metric | Description |
|---|---|
| Time to First Token (TTFT) | Under normal network conditions, the first Token is typically returned within hundreds of milliseconds, depending on the model version and system load |
| Throughput | Stable Token generation speed is guaranteed within rate limits |
| Concurrency Support | Concurrent invocation quotas are provided based on account tier |
The above performance metrics are reference values. Actual performance may be affected by network conditions, request parameters, system load, and other factors.
3. Service Access and Usage
3.1 Access Methods
| Access Method | Description |
|---|---|
| HTTP API | RESTful-style HTTP interface supporting both streaming and non-streaming responses |
| Python SDK | Official Python client library that encapsulates API invocation details |
| Java SDK | Official Java client library, suitable for developers in the Java ecosystem |
| OpenAI-Compatible Interface | Compatible with the OpenAI API invocation format, enabling quick migration and integration |
For detailed access methods and code examples, please refer to the Interface Documentation.
3.2 Authentication Mechanism
- All API requests must include a valid API Key for identity authentication.
- API Keys should be transmitted via HTTP Headers or request parameters and must not be hardcoded in front-end code or public repositories.
- You may create, manage, and revoke API Keys in the console, with support for multiple Keys in parallel.
3.3 Rate Limits
To ensure service quality and fair usage, we impose the following limits on API invocations:
| Limit Type | Description |
|---|---|
| Request Rate Limit (RPM) | Maximum number of requests allowed per minute |
| Token Rate Limit (TPM) | Maximum number of Tokens allowed to be consumed per minute |
| Concurrent Request Limit | Maximum number of requests being processed simultaneously |
Specific limit quotas are determined by account tier and model version, as displayed in the console. To request a higher quota, you may apply through the console or contact our business team.
