Access Preparation

Obtain refresh_token from Zhipu

Enter Zhipu Qingyan and start a random conversation, then press F12 to open the developer tools. Find the value of tongyi_sso_ticket in Application > Cookies, which will be used as the Bearer Token value for Authorization: Authorization: Bearer TOKEN

Agent Access

Open a window of Agent Chat, the ID in the url is the ID of the Agent, which is the parameter of model.

Multiple Account Access

You can provide multiple account chatglm_refresh_tokens and use , to join them:

Authorization: Bearer TOKEN1,TOKEN2,TOKEN3

The service will pick one each time a request is made.

Docker Deployment

Please prepare a server with a public IP and open port 8000.

Pull the image and start the service

docker run -it -d --init --name step-free-api -p 8000:8000 -e TZ=Asia/Shanghai vinlic/step-free-api:latest

check real-time service logs

docker logs -f glm-free-api

Restart service

docker restart glm-free-api

Shut down service

docker stop glm-free-api

Docker-compose Deployment

version: '3'

services:
  glm-free-api:
    container_name: glm-free-api
    image: vinlic/glm-free-api:latest
    restart: always
    ports:
      - "8000:8000"
    environment:
      - TZ=Asia/Shanghai

Render Deployment

Attention: Some deployment regions may not be able to connect to Kimi. If container logs show request timeouts or connection failures (Singapore has been tested and found unavailable), please switch to another deployment region!

Attention: Container instances for free accounts will automatically stop after a period of inactivity, which may result in a 50-second or longer delay during the next request. It is recommended to check Render Container Keepalive

1. Fork this project to your GitHub account.

2. Visit Render and log in with your GitHub account.

3. Build your Web Service (New+ -> Build and deploy from a Git repository -> Connect your forked project -> Select deployment region -> Choose instance type as Free -> Create Web Service).

4. After the build is complete, copy the assigned domain and append the URL to access it.

Vercel Deployment

Note: Vercel free accounts have a request response timeout of 10 seconds, but interface responses are usually longer, which may result in a 504 timeout error from Vercel!

Please ensure that Node.js environment is installed first.

npm i -g vercel --registry http://registry.npmmirror.com
vercel login
git clone https://github.com/LLM-Red-Team/glm-free-api
cd glm-free-api
vercel --prod

Native Deployment

Please prepare a server with a public IP and open port 8000.

Please install the Node.js environment and configure the environment variables first, and confirm that the node command is available.

Install dependencies

npm i

Install PM2 for process guarding

npm i -g pm2

Compile and build. When you see the dist directory, the build is complete.

npm run build

Start service

pm2 start dist/index.js --name "glm-free-api"

View real-time service logs

pm2 logs glm-free-api

Restart service

pm2 reload glm-free-api

Shut down service

pm2 stop glm-free-api

Notification

Nginx Anti-generation Optimization

If you are using Nginx reverse proxy glm-free-api, please add the following configuration items to optimize the output effect of the stream and optimize the experience.

# Turn off proxy buffering. When set to off, Nginx will immediately send client requests to the backend server and immediately send responses received from the backend server back to the client.
proxy_buffering off;
# Enable chunked transfer encoding. Chunked transfer encoding allows servers to send data in chunks for dynamically generated content without knowing the size of the content in advance.
chunked_transfer_encoding on;
# Turn on TCP_NOPUSH, which tells Nginx to send as much data as possible before sending the packet to the client. This is usually used in conjunction with sendfile to improve network efficiency.
tcp_nopush on;
# Turn on TCP_NODELAY, which tells Nginx not to delay sending data and to send small data packets immediately. In some cases, this can reduce network latency.
tcp_nodelay on;
#Set the timeout to keep the connection, here it is set to 120 seconds. If there is no further communication between client and server during this time, the connection will be closed.
keepalive_timeout 120;

Token Statistics

Since the inference side is not in glm-free-api, the token cannot be counted and will be returned as a fixed number!!!!!
