Getting Started

The CEORater API is public-keyed. Anyone can use it with the shared public key CEORATER_PUBLIC_V1. You can pass this key in the x-api-key header or as an api_key query parameter.

1. Quick browser test

Paste this URL into your browser to fetch Apple Inc. (AAPL) as raw JSON: 

https://ceorater-api.onrender.com/v1/company/AAPL?format=raw&api_key=CEORATER_PUBLIC_V1

2. cURL example

curl -i "https://ceorater-api.onrender.com/v1/company/AAPL?format=raw&api_key=CEORATER_PUBLIC_V1"

3. Minimal Python example

import requests

BASE_URL = "https://ceorater-api.onrender.com"
API_KEY = "CEORATER_PUBLIC_V1"

resp = requests.get(
    f"{BASE_URL}/v1/company/AAPL",
    params={"format": "raw"},
    headers={"x-api-key": API_KEY},
    timeout=10,
)
resp.raise_for_status()
print(resp.json())

Authentication

Public (free) key: CEORATER_PUBLIC_V1. Send it in the x-api-key header. We may rotate this key; if requests stop working, check the API Viewer for the current key.

All API requests require authentication using an API key. You can authenticate in two ways:

Option 1: Header (Recommended)

x-api-key: your_api_key_here

Option 2: Query Parameter

GET /v1/companies?api_key=your_api_key_here

401 Unauthorized: Missing or invalid API key

Endpoints
