Other language examples

If you are not using Python SDK, you can call the REST API directly from any language.

Node.js

Copyconst apiKey = "sixfinger_xxx";

const response = await fetch("https://sfapi.pythonanywhere.com/api/v1/chat", {
  method: "POST",
  headers: {
    "X-API-Key": apiKey,
    "Content-Type": "application/json"
  },
  body: JSON.stringify({ message: "Hello from Node.js" })
});

const data = await response.json();
console.log(data.response);

Java

CopyOkHttpClient client = new OkHttpClient();

String json = "{"message":"Hello from Java"}";
RequestBody body = RequestBody.create(json, MediaType.parse("application/json"));

Request request = new Request.Builder()
    .url("https://sfapi.pythonanywhere.com/api/v1/chat")
    .addHeader("X-API-Key", "sixfinger_xxx")
    .post(body)
    .build();

try (Response response = client.newCall(request).execute()) {
    System.out.println(response.body().string());
}

C#

Copyusing System.Net.Http;
using System.Text;

var client = new HttpClient();
client.DefaultRequestHeaders.Add("X-API-Key", "sixfinger_xxx");

var content = new StringContent("{"message":"Hello from C#"}", Encoding.UTF8, "application/json");
var res = await client.PostAsync("https://sfapi.pythonanywhere.com/api/v1/chat", content);
var body = await res.Content.ReadAsStringAsync();

Console.WriteLine(body);

Go

Copypackage main

import (
    "bytes"
    "fmt"
    "io"
    "net/http"
)

func main() {
    payload := []byte(`{"message":"Hello from Go"}`)

    req, _ := http.NewRequest("POST", "https://sfapi.pythonanywhere.com/api/v1/chat", bytes.NewBuffer(payload))
    req.Header.Set("X-API-Key", "sixfinger_xxx")
    req.Header.Set("Content-Type", "application/json")

    resp, _ := http.DefaultClient.Do(req)
    defer resp.Body.Close()

    b, _ := io.ReadAll(resp.Body)
    fmt.Println(string(b))
}
