Connect Perplexity with API Key – StackOne Hub

Link a Perplexity account in the StackOne Hub using API Key. End-user guide to authorize the integration and start using Perplexity actions.

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.

1. Sign in to the Perplexity API Console

   Sign in to the Perplexity API Console.

   • In the left sidebar under Group, click Billing.
2. Add a payment method and buy credits

   On the Billing page, the API credit balance shows your remaining balance. Add a payment method, then load credits.

   • Click Add payment method, enter your card details, and save it.
   • The Buy more credits button is disabled until you have filled in valid card details and saved a payment method. Only after the payment method is successfully added does the Buy more credits button become enabled.
   • Click Buy more credits and choose an amount to load (there is no minimum; a small amount is enough to start).
