Here’s a simple JavaScript code example for calling the OpenCorporates API to retrieve data about a specific company:

const fetch = require('node-fetch');

const apiKey = 'YOUR_API_KEY';
const companyName = 'example-corp';
const url = `https://api.opencorporates.com/v0.4/companies/search?q=${companyName}&api_token=${apiKey}`;

fetch(url)
    .then(response => response.json())
    .then(data => {
        console.log('Company Data:', data);
    })
    .catch(error => {
        console.error('Error fetching data from OpenCorporates API:', error);
    });

Make sure to replace 'YOUR_API_KEY' with your actual OpenCorporates API key before running the code. This example demonstrates how to initiate a search for a specific company and log the retrieved data to the console.

How to Get an OpenCorporates API Key

The OpenCorporates API requires an api_token on every request — there is no unauthenticated access.

1. Go to the API account signup page.
2. Choose your account type. Free API accounts are available if your project publishes the data under an open licence with share-alike attribution; commercial use needs a paid plan that removes the open-data restriction.
3. Complete the self-serve signup — your API token is issued to your account immediately.
4. Copy the token from your API account dashboard.

Free accounts are rate-limited to roughly 50 requests/day and 200 requests/month; higher limits depend on your plan. Check current tiers on the API accounts page.

Pass the token as the api_token query parameter:

https://api.opencorporates.com/v0.4/companies/search?q=acme&api_token=YOUR_API_TOKEN

Keep your token private — anyone with it can consume your quota.
