Unified AI API Gateway
One API to govern enterprise AI: connect supported global and China-based models, and apply routing, budget, key-management, metering and audit policies centrally.
One API for supported global and China-based models
Applications talk only to the gateway, which handles authentication, budgets, policy routing, metering and audit; the model side connects to supported global and China-based providers. Figures below are an indicative simulation.
- Enterprise 1,000,000
- Dept · R&D 420,000
- Staff · Engineer A 60,000
- Key · ide-prod 20,000
A control plane for enterprise AI
Departments sign up for their own provider accounts, keys end up in code, and finance reconciles several invoices at month end — this is where most enterprises land once model usage scales. Uncontrolled budgets, unclear ownership and provider lock-in share one cause: calls do not pass through a governed entry point.
The GSS Unified AI API Gateway brings enterprise model traffic into one control plane. Applications talk only to the gateway; the gateway applies authentication, budget validation, policy routing, metering and audit before requests reach providers; the model side connects to supported global and China-based providers.
Four core values
| Value | How |
|---|---|
| Integrate once | One API to supported global and China-based models; compatible applications replace only the endpoint and key |
| Control spend before it occurs | Enterprise → department → staff → key budgets enforced before each request; stopped at the limit |
| Allocate cost by team and application | Every call has an owner; cost rolls up by department / application / model and exports for reconciliation |
| Maintain traceable access and usage records | Key creation, use, change and revocation plus every call are logged end to end and filterable |
What the gateway does in the request path
- Application side: agent applications (customer service · marketing · ticketing), enterprise applications (CRM · OA · ERP · knowledge base), new business lines added as needed.
- Gateway: authentication → budget and quota validation → policy routing → metering → audit trail.
- Model side: supported global and China-based providers. Overseas models are reached over GSS cross-border connectivity and GSS PoPs with an auditable path.
Multi-level budgets, enforced before spend
Enterprise total → department → staff → each API key. Rule: allocation at any level may not exceed what that level holds; over-allocation is rejected; each call is validated in real time and stopped at the limit. Budget is a pre-request policy, not a month-end reconciliation.
Monitor usage, cost allocation and model performance
| Module | Capability |
|---|---|
| Usage and cost | Multi-dimensional aggregation · export · overspend alerts |
| Contract orders | Quota issued to the enterprise account per order |
| Model pricing | Transparent prices for supported models |
| Accounts and departments | Enterprise / department / staff tiers, budget ownership |
| Key wizard | Step-by-step creation, mandatory department ownership |
The dashboard shows this month’s usage, call count, tokens (input and output counted separately) and remaining budget in real time; department detail can be filtered by model and period and exported. Once cost is attributed to departments and applications, business value is assessed by the enterprise against its own output.
Manage the full lifecycle of every API key
- Create — name → department → authorised providers → budget → expiry.
- Use — mandatory department ownership; model scope bounded by provider.
- Rotate — external keys recommended to expire at 90 days, reminder 7 days ahead.
- Revoke — one-click recovery when staff leave or projects close; budget released automatically.
- Audit — creation, use and changes logged end to end.

Onboarding path
- Assess — confirm interfaces, authentication, network and security-review requirements; check the compatibility list.
- Connect — compatible applications switch endpoint and key to the gateway.
- Allocate — build multi-level budgets and keys, scoped by provider.
- Operate — usage and cost visible in real time; GSS maintains routing policies and the compatibility list.
Migration time depends on application interfaces, security review and deployment scope; we provide a plan after assessment. The gateway is delivered alongside GSS cross-border connectivity, managed operations and AI infrastructure — where the model runs, how traffic travels, where compute sits and who operates it are owned by one team.

Platform capability matrix
Three categories are stated for each area — supported today, configurable, and integrations that require assessment. Support is defined by the compatibility list for the current release.
Unified access
One API to supported global and China-based providers, protocol-compatible.
- Supported: chat and completion interfaces of mainstream global and China-based providers
- Configurable: provider priority, model aliases, regional endpoints
- Requires assessment: provider-specific features (tool calling, multimodal) item by item
Budgets and quotas
Multi-level budgets enforced before spend, not at month end.
- Supported: four budget levels (enterprise / department / staff / key), over-allocation rejected
- Configurable: alert thresholds, reset periods, freeze policies
- Requires assessment: budget sync with your finance systems
Policy routing
Policy-based switching across configured model endpoints.
- Supported: routing rules by provider / model / department, endpoint failure switching
- Configurable: cost-first, latency-first, region-first policies
- Requires assessment: feature-equivalence mapping across providers
Keys and audit
Every key has an owner, an expiry and a record.
- Supported: key wizard, mandatory department ownership, one-click revocation, end-to-end audit
- Configurable: rotation period, reminder timing, export format
- Requires assessment: integration with your SIEM / IAM
Observability
Usage, cost allocation and model performance in one view.

Delivery process
Assess and connect
Confirm interface compatibility, authentication, network and security-review requirements. Compatible applications migrate by switching the endpoint; timing depends on interfaces, security and deployment scope.
Allocate budgets and keys
Build the enterprise → department → staff → key budget tree along the org chart; department ownership is mandatory and each key's model scope is bounded by provider.
See usage and cost
Usage, call count, tokens and remaining budget are visible in real time; filter by department / application / model / period and export for reconciliation.
Govern continuously
Overspend alerts and automatic blocking, scheduled key rotation and recovery, monthly cost roll-up; GSS maintains routing policies and the compatibility list.

FAQ
What does the gateway add over the providers' own consoles?
A provider console manages one provider, one ceiling and one invoice. The gateway manages several supported providers from one place, enforces enterprise → department → staff → key budgets before spend, rolls cost up by department / project / key automatically and offers end-to-end, multi-dimensional call auditing.
Do we have to change application code?
Not for compatible applications — replace the endpoint and key with those issued by the gateway. Migration time depends on interfaces, authentication, network and security review; we provide a plan after assessment.
How are budgets enforced?
The enterprise holds the total budget, splits it to departments, departments split to staff, and it lands on each key. Allocation at any level may not exceed what that level holds; each call is validated in real time and stopped at the limit.
What happens to a key when someone leaves or a project closes?
One-click revocation in the console; the budget is released back to the parent level. Creation, use, change and revocation are all logged. External keys are recommended to expire at 90 days with a reminder 7 days ahead.
Which models are supported?
See the compatibility list for the current release, which states provider, model, protocol, feature and deployment support and is updated per release. Ask us for the latest list.
How are overseas models kept stable?
Overseas calls travel over GSS cross-border connectivity and GSS PoPs in Hong Kong / Tokyo / Singapore / Los Angeles with an auditable path. Policy-based switching across configured endpoints lets traffic move to another configured endpoint when one provider rate-limits or fails.
How is it paid for?
Quota is issued to the enterprise account against contract orders and managed by GSS, so you no longer contract with multiple overseas providers separately.
Is this a GSS product?
The GSS Unified AI API Gateway is operated by GSS, available as a managed service or deployed in your data centre / dedicated cloud, and delivered together with GSS connectivity, managed operations and AI infrastructure services.
