Question: Are the 500 free requests on a monthly basis?
Answer: No, the 500 requests are for one time, without a date of expiry. That means you can use them in one day or one year.

Question: What happens after I spend the 500 free requests?
Answer: Your account will be suspended, or if you want to proceed using our services you can upgrade to a paid model.

Question: Can I use these 500 requests on all your APIs or just some?
Answer: You can make requests to all our APIs with the same API key, and you can do it 500 times before your account is depleted.
