Quickstart

Create an OpenGateway API key, call Chat Completions with curl or the OpenAI SDK, check the public model catalog, and review your request in the dashboard.

1. Create an API key#

Sign in to the OpenGateway dashboard, open API Keys, and choose Create new key. Copy the key when it is shown; you cannot view it again after closing the dialog. Keep it in a server-side environment variable:

Bash
export OPENGATEWAY_API_KEY="YOUR_API_KEY"

See API keys for key management and security guidance.

2. Make a request with curl#

Send a Chat Completions request to the shared base URL. This example uses the current openai/gpt-5-mini model ID.

Bash
curl "https://apis.opengateway.ai/v1/chat/completions" \
  -H "Authorization: Bearer $OPENGATEWAY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-5-mini",
    "messages": [{"role": "user", "content": "Say hello in one sentence."}]
  }'

3. Use the OpenAI SDK#

Point the SDK at OpenGateway and use a model ID from the catalog.

Python#

Python
import os


from openai import OpenAI


client = OpenAI(
    api_key=os.environ["OPENGATEWAY_API_KEY"],
    base_url="https://apis.opengateway.ai/v1",
)


response = client.chat.completions.create(
    model="openai/gpt-5-mini",
    messages=[{"role": "user", "content": "Say hello in one sentence."}],
)
print(response.choices[0].message.content)

TypeScript#

TypeScript
import OpenAI from "openai";


const client = new OpenAI({
  apiKey: process.env.OPENGATEWAY_API_KEY,
  baseURL: "https://apis.opengateway.ai/v1",
});


const response = await client.chat.completions.create({
  model: "openai/gpt-5-mini",
  messages: [{ role: "user", content: "Say hello in one sentence." }],
});
console.log(response.choices[0].message.content);

4. Inspect the catalog and dashboard#

GET /v1/models is public and does not require a key. Use it to check current model IDs, modalities, and supported endpoints:

Bash
curl "https://apis.opengateway.ai/v1/models"

The public response does not include pricing. Browse Models for model details and current pricing. After making a request, open the dashboard and usage and logs to inspect activity. See billing for credit and payment information.
