Question 1

How do I use the Perplexity API?

Accepted Answer

Create an LLM Gateway API key and point any OpenAI-compatible SDK at https://api.llmgateway.io/v1. Set the model to perplexity-search-fast. On pay-as-you-go keys, perplexity/perplexity-search-fast pins every request to Perplexity; DevPass coding plans do not support provider pinning. You do not need a separate Perplexity account or SDK.

Question 2

Which Perplexity models are available?

Accepted Answer

LLM Gateway serves 3 Perplexity models: Perplexity Search Fast, Perplexity Search, Sonar. Each model page lists per-token pricing, context window and capabilities.

Question 3

Does Perplexity train on API data?

Accepted Answer

No. Perplexity's published policy states that API traffic is not used for model training.

Question 4

Where is Perplexity based?

Accepted Answer

Perplexity is headquartered in United States. LLM Gateway shows each provider's location and data policy so you can route by compliance requirements.

Question 5

What happens if the Perplexity API is down?

Accepted Answer

When you request a model without a provider prefix, LLM Gateway retries failed requests on other providers that serve the same model, so an outage at Perplexity does not have to take your app down. Send X-No-Fallback: true with a provider-pinned model when every request must reach Perplexity.
