Where can I find api links?

Question

Python

Where can I find api links for the discord bot?
That is, in order for the bot to display random photos of something, for example, cats, on command.
Like this command:
@bot.command()
async def fox(ctx):
response = requests.get(' https://some-random-api.ml/img/fox ') # Get-request
json_data = json.loads(response.text) # Extract the JSON

embed = discord.Embed(color = 0xff9900, title = 'Random Fox') # Create an Embed
embed.set_image(url = json_data['link']) # Set the Embed image 'a
await ctx.send(embed = embed) # Send Embed

The problem is that I can't find a link like this: https://some-random-api.ml/img/fox .
