The Perplexity API is prepaid and billed separately from any Perplexity subscription, so you must add API credits before your key can make billed calls. Your key is shown only once when you create it, so copy it right away — you cannot view it again later.

​
Add API credits

The Perplexity API draws from a prepaid API credit balance that is separate from any Perplexity subscription. Add a payment method and load credits before creating a key.
