Sample code and API for GLM-5.3 Flash
GonkaGate accepts OpenAI-compatible requests and sends them to Gonka Network.
Get your API key
Create an API key from your GonkaGate dashboard and set it as an environment variable:
Create API keyexport GONKAGATE_API_KEY=gp-your-api-keyMake your first request
Use zai-org/glm-5.3-flash.
GonkaGate provides an OpenAI-compatible chat completions API for Gonka Network models. You can call it directly or use common OpenAI SDKs.
Set the base URL to https://api.gonkagate.com/v1 and pass your GonkaGate API key in the Authorization header.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://api.gonkagate.com/v1",
apiKey: process.env.GONKAGATE_API_KEY
});
const response = await client.chat.completions.create({
model: "zai-org/glm-5.3-flash",
messages: [
{ role: "user", content: "What is the meaning of life?" }
]
});
console.log(response.choices[0].message.content);Using third-party SDKs
For SDK and framework setup examples, see SDK documentation and integrations.
Enable streaming
Add "stream": true to your request body to receive responses as server-sent events:
curl -N https://api.gonkagate.com/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $GONKAGATE_API_KEY" \
-d '{
"model": "zai-org/glm-5.3-flash",
"stream": true,
"messages": [
{"role": "user", "content": "Hello"}

Parameters
| Name | Type | Default | Description |
|---|---|---|---|
| reasoning | map | — | Controls reasoning behavior for models that support thinking tokens, including reasoning effort and whether reasoning is included in the response. |
| max_tokens | integer | — | Sets the upper limit for the number of tokens the model can generate in response. |
| temperature | float | 1 | Influences the variety of the model's responses. |
| top_p | float | 1 | Limits choices to the smallest set of likely tokens whose probabilities add up to this value. |
| seed | integer | — | Samples deterministically when supported, so repeated requests with the same seed and parameters can return the same result. |
| presence_penalty | float | 0 | Adjusts how often the model repeats specific tokens already used in the input. |
| response_format | map | — | Requests a specific output format when the model supports it. |
| tools | array | — | Tool calling parameter following OpenAI's tool calling request shape. |
| tool_choice | string or object | — | Controls which tool, if any, is called by the model. |
| logprobs | boolean | — | Requests output-token log probabilities when supported. |
| top_logprobs | integer | — | Specifies how many most likely tokens to return at each token position, each with an associated log probability. |
