GLM 5.2 API Key: Create and Use a glm52.site API Key

If you are searching for a GLM 5.2 API key, the practical path on this site is to start from the GLM 5.2 API access page, sign in, and open the API console from there.

The API access flow on glm52.site is built for developers who want to move beyond one-off playground prompts and connect GLM 5.2 to coding tools, internal agents, evaluation harnesses, and product prototypes.

Where to create a GLM 5.2 API key

Use the site API page:

Plan GLM 5.2 API access

After login, manage keys in the API console:

Open the API console

The API console lets you create named keys for production, staging, and experiments. The full secret is shown only once, so copy it into your server-side secret manager when it is created.

glm52.site API endpoint

Use the glm52.site chat completions endpoint:

https://glm52.site/api/v1/chat/completions

Example request:

curl https://glm52.site/api/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_GLM52_API_KEY" \
  -d '{
    "model": "glm-5.2",
    "messages": [
      { "role": "user", "content": "Review this React component for bugs." }
    ]
  }'

For JavaScript server code:

const response = await fetch("https://glm52.site/api/v1/chat/completions", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    Authorization: "Bearer " + process.env.GLM52_API_KEY,
  },
  body: JSON.stringify({
    model: "glm-5.2",
    messages: [
      { role: "user", content: "Generate a pricing page headline." },
    ],
  }),
});

const data = await response.json();

Keep the key server-side

Do not put a GLM 5.2 API key in browser JavaScript, public GitHub repositories, mobile app bundles, or static front-end config. Treat it as a production secret.

Recommended setup:

• create one key per app, environment, or customer
• store the key as GLM52_API_KEY in server-side environment variables
• route browser requests through your own backend
• revoke leaked keys from the API console immediately
• track usage against your glm52.site credit balance

Credits and billing

API usage on this site is connected to the GLM 5.2 credit system. Use GLM 5.2 Pricing or the live pricing page to compare monthly plans, prepaid top-ups, playground usage, and API-ready credit balances.

If you are not ready to create an API key yet, test prompts first in the GLM 5.2 Playground. Once a prompt pattern works, move it into the API workflow through API access.
