One Platform
Unlimited APIs
Unified access to multiple API services through a single interface. One account, one authentication system, centralized management for all your API needs.
// Access any API through unified endpoints
const headers = {
'Authorization': 'Bearer YOUR_API_KEY',
'Content-Type': 'application/json'
};
// Send SMS
await fetch('https://api.apiharness.com/v1/sms/send', {
method: 'POST', headers,
body: JSON.stringify({ to: '+1234567890', message: 'Hello!' })
});
// Convert currency
await fetch('https://api.apiharness.com/v1/currency/convert?from=USD&to=EUR&amount=100', { headers });
// Convert file format
await fetch('https://api.apiharness.com/v1/files/convert', {
method: 'POST', headers, body: formData
});Why API Harness?
