Authentication

All requests to the MoneyLine API must include a valid API key. Pass your key via the x-api-key header on every request. Requests without a valid key will be rejected with a 401 status code.

Getting an API Key

Create a free account on the sign-up page.
Open your dashboard.
Click Create Key to generate a new API key.

Your key will look something like ml_live_abc123.... Keep it secret — treat it like a password.

Example Request

Include the x-api-key header with your key in every request:

Authenticated request

curl -H "x-api-key: ml_live_abc123..." \

Error Responses

If your API key is missing or invalid, the API returns a 401 Unauthorized response:

401 — Invalid or missing key

{
  "success": false,
  "error": {
    "code": 401,
    "message": "Valid API key required. Pass x-api-key header."
  }
}

If your key is valid but your plan does not include the requested resource, the API returns a 403 Forbidden response:

403 — Tier-gated resource

{
  "success": false,
  "error": {
    "code": 403,
    "message": "Your plan does not include access to this resource."
  }
}
