Model Response Comparator API

Category: developer

Compare how different AI model personas (GPT-4, Claude, Gemini) respond to the same prompt side-by-side.

Endpoint

POST https://anythingtext.com/api/tools/modelcompare

API Key Required Content-Type: application/json

API Key

This API requires an API key. No login or OAuth is needed. Generate your key from the API Keys section in your dashboard settings.

Include the X-API-Key header in all API requests:

X-API-Key: atk_your_api_key_here

Rate Limiting

API requests are limited to 60 requests per minute per user. If you exceed this limit, the API returns a 429 Too Many Requests response.

Every response includes rate limit headers:

When rate limited, the response body contains:

{ "error": "Rate limit exceeded. Maximum 60 requests per minute.", "retryAfter": 42, "limit": 60 }

Code Samples

const response = await fetch('/api/tools/modelcompare', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ prompt: 'Explain recursion to a beginner' })
});
const data = await response.json();
console.log('GPT-4:', data.gpt4);
console.log('Claude:', data.claude);
console.log('Gemini:', data.gemini);

import requests

response = requests.post('https://anythingtext.com/api/tools/modelcompare',
    json={'prompt': 'Explain recursion to a beginner'})
data = response.json()
print('GPT-4:', data['gpt4'])
print('Claude:', data['claude'])
print('Gemini:', data['gemini'])
