The AI Stats Gateway gives you a single, unified API surface for accessing multiple model providers. Follow this guide to create an API key, send your first request, and adopt the conventions that keep integrations production ready.

​
Before you begin

Make sure you have the following in place:
  • An AI Stats account with Gateway access.
  • At least one API key generated from your dashboard.
  • An HTTP client such as curl, fetch, or axios.
  • A model ID supported by the Gateway (for example gpt-5-nano-2025-08-07).

​
1. Create and store an API key

  1. Log in to the AI Stats dashboard.
  2. Navigate to Gateway -> API Keys.
  3. Create a new key, give it a descriptive name, and copy the generated value.
  4. Store the key securely using your secret manager or environment variables:
# .env
AI_STATS_API_KEY="aistats_v1_sk_<kid>_<secret>"
Tip Rotate keys regularly and remove any that are no longer needed. This keeps access scoped and auditable.

​
2. Choose an endpoint and model

Pick the endpoint that matches your use case. The Gateway normalizes payloads across providers, so request shapes are consistent:
EndpointWhen to use it
/v1/chat/completionsConversational interfaces, agents, and assistants.
/v1/responsesMulti-step reasoning and structured responses.
/v1/messagesAnthropic-compatible messages API.
/v1/moderationsSafety and content policy checks.
/v1/images/generationsImage generation from text prompts.
Refer to the API Reference for the complete list of supported parameters and responses.

​
3. Send a request

Here is a minimal curl example using the chat completions endpoint: 
curl https://api.phaseo.app/v1/chat/completions \
    -H "Authorization: Bearer $AI_STATS_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
        "model": "gpt-5-nano-2025-08-07",
        "messages": [
            { "role": "system", "content": "You are a helpful assistant." },
            { "role": "user", "content": "Explain the benefits of AI." }
        ]
    }'

​
4. Configure environments

Store your API key in environment variables for different environments: 
# .env.local
AI_STATS_API_KEY="aistats_v1_sk_<kid>_<secret>"
AI_STATS_BASE_URL="https://api.phaseo.app/v1"
When making requests, always include the Authorization header with your API key: 
Authorization: Bearer $AI_STATS_API_KEY
