Python requests-bibliotheek voor API's

Een schema dat een verzoek aan de Art Institute of Chicago API toont

Python requests-bibliotheek voor API's

Importeer de bibliotheek
```
import requests
```

Geef een URL op

url = "https://api.artic.edu/api/v1/artworks/search"

Geef queryparameters op
```
querystring = {"q":keyword}
```

Haal de response op

response = requests.request("GET", url, params=querystring)

¹ https://api.artic.edu/docs/#quick-start

De functie verpakken

import requests

def get_artwork(keyword):
    url = "https://api.artic.edu/api/v1/artworks/search"
    querystring = {"q":keyword}
    response = requests.request("GET", url, params=querystring)
    return response.text

Context toevoegen

response = client.chat.completions.create(
    model="gpt-4o-mini",

    messages=[
{"role": "system",
 "content": "You are an AI assistant, a specialist in history 
    of art. You should interpret the user prompt, and based on it extract one 
    keyword for recommending artwork related to their preference."},

{"role": "user", 
 "content": "I don't have much time to visit the museum and would 
    like some recommendations. I like the seaside and quiet places."}
],
