Quick start

Keep API keys secret. Use them on your server only.

cURL

curl 'https://isthisimageai.org/api/v1/detect' \
  -H "Authorization: Bearer $ISTHISIMAGE_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -F 'image=@photo.jpg'

Python

import os, uuid, requests

with open("photo.jpg", "rb") as image:
    response = requests.post(
        "https://isthisimageai.org/api/v1/detect",
        headers={"Authorization": "Bearer " + os.environ["ISTHISIMAGE_API_KEY"],
                 "Idempotency-Key": str(uuid.uuid4())},
        files={"image": ("photo.jpg", image, "image/jpeg")}, timeout=120)
print(response.status_code, response.json())

Node.js

import { readFile } from 'node:fs/promises';

const form = new FormData();
form.set('image', new Blob([await readFile('photo.jpg')], { type: 'image/jpeg' }), 'photo.jpg');
const response = await fetch('https://isthisimageai.org/api/v1/detect', {
  method: 'POST',
  headers: { Authorization: 'Bearer ' + process.env.ISTHISIMAGE_API_KEY,
             'Idempotency-Key': crypto.randomUUID() },
  body: form
});
console.log(response.status, await response.json());
