Authentication

Indexed uses API key authentication. You will need to obtain a key before making requests:

1. Open the official documentation at the link below.
2. Look for the sign-up / API-key section and create an account.
3. Copy your key and send it with every request (the docs show the exact header or query parameter to use).

Keep the key server-side and never commit it to public repositories.

HTTPS & CORS

Getting Started

2. Obtain an API key (see Authentication above).
3. Make a test request with curl or your favourite HTTP client, sending the key as documented.

Rate Limits & Notes

• Rate limits, quotas, and free-tier terms are defined by the provider — always check the official documentation for Indexed before scaling up.
