A branded AI API portal is useful only when a developer can move from “I found a service” to “my first request succeeded” without receiving credentials over chat or guessing which URL to call.
This guide presents a practical onboarding flow for an Ace Data Cloud white-label API site. The business goal is legitimate resale: you operate the brand, catalog, pricing, documentation, and customer support; customers discover the offer and make valid purchases under the applicable distribution rules. It is not a promise of guaranteed income, a separate gateway, or a separate tenant identity system.

The architecture: separate discovery from execution
A clean onboarding flow has two surfaces:
- Page domain: the branded portal where customers browse services, compare prices, read documentation, register, and manage their account.
- API base URL: the endpoint applications call with a customer-owned API key.
Do not treat these as interchangeable. A documentation page is not a base URL, and an API endpoint is not an onboarding page. Use placeholders in reusable instructions:
Portal: https://developers.example.com
Base URL: https://api.example.com
Docs: https://developers.example.com/docs/example-service
API Key: obtained by each customer from their own console
If you later configure custom domains, obtain the required CNAME targets from your own console. Never copy DNS values from another tenant or a tutorial screenshot.
Step 1: create the smallest viable developer portal
Sign in with the operator account and open Site Management. Create a site with a recognizable brand name and a short prefix. According to the current setup guide, the prefix uses 3–32 lowercase letters, digits, or hyphens; it cannot begin or end with a hyphen or contain consecutive hyphens.
Start with only the essentials:
| Area | Minimum useful configuration |
|---|---|
| Site settings | Name, one-sentence description, logo, favicon |
| Homepage | Clear audience and primary use case |
| Catalog | A few services you can explain and support |
| Pricing | Customer-visible prices reviewed before launch |
| Documentation | One complete quickstart per promoted service |
| Support | A real contact route and response expectations |
| Legal | Terms and privacy information appropriate to your operation |
A system-provided domain is ideal for initial validation. Open it in a private browser window and verify the homepage, catalog, docs, and login entry before introducing DNS and HTTPS variables. Basic creation can be quick when the operator is already signed in and has a name and prefix ready, but domain setup and production readiness are separate work.
Step 2: publish one onboarding contract
Customers should not need a video call to identify the four inputs required by their application. Put this contract in the service documentation:
Base URL: <YOUR_API_BASE_URL>
API key: <CUSTOMER_API_KEY>
Service: <PUBLIC_SERVICE_OR_MODEL_NAME>
Docs: <YOUR_SERVICE_DOCUMENTATION_URL>
Preserve the public service or model identifier required by the technical documentation. Renaming it for marketing while silently changing the value expected by code creates avoidable failures.
Also distinguish supported integration styles. A native endpoint, an OpenAI-compatible interface, and MCP are different contracts. For a first onboarding session, choose the one the customer actually needs instead of asking them to test every available interface.
Step 3: make credential ownership explicit
The customer should register or sign in from your page domain and then create a key in their own console. The operator’s key must never become a shared credential.
A safe onboarding checklist is:
- create a separate key for each customer project and environment;
- store it in server-side secrets or a secure tool configuration;
- never place it in browser code, screenshots, public repositories, or support chat;
- use a descriptive key name, expiration, usage limit, and allowed-API restrictions when the console and service support them;
- do not confuse an account token with an application API key.
The current credential form supports fields for a name and controls such as usage limits, expiration, and allowed APIs. Catalog visibility is not authorization: hiding a service from the storefront does not by itself constrain an otherwise valid key.
This white-label model uses a shared underlying identity system; it should not be described as delivering an independent tenant identity database. Your value is the operated experience around brand, selection, pricing, documentation, acquisition, and support.
Step 4: validate with the smallest billable request
Before a customer runs a batch, long video, or other expensive job, ask them to review the current price and send the smallest meaningful request shown in the service documentation.
A generic server-side configuration might look like this:
export AI_BASE_URL="https://api.example.com"
export AI_API_KEY="replace-with-the-customer-owned-key"
Do not invent a universal request body: paths, parameters, synchronous responses, and asynchronous task polling vary by service. Copy the minimum example from the selected service’s current documentation and replace only the documented base URL, key, and required inputs.
Acceptance requires two observations:
- the request reaches a terminal successful result; and
- the corresponding usage record appears in the customer console with the expected service and consumption.
For asynchronous media APIs, a task ID means “submitted,” not “completed.” Poll exactly as that service’s documentation specifies.
Step 5: turn onboarding into an operating loop
Monetization happens only when acquisition leads to attributed customers who complete valid purchases under the current distribution rules. Therefore, measure a funnel you can improve:
qualified visit → registration → docs viewed → key created
→ first successful request → usage record → valid purchase → repeat usage
Do not advertise guaranteed profit, fixed daily earnings, or a universal per-call commission. Commercial results depend on customer acquisition, support quality, pricing, service fit, and the rules currently shown in the operator console.
After the test, the customer can disable or delete a test-only key once they verify it is not used by production. For support, request the timestamp, path, status code, and a safe request identifier—never the complete authorization header.
The key design choice is simple: launch a narrow, verifiable path before a broad catalog. One well-documented service with secure customer-owned credentials and a measurable first-call checklist is more operable than dozens of listings that customers cannot integrate.
