Perplexity API FAQ
Everything you need to know about estimating and optimizing your API costs.
The Perplexity API (also known as the Sonar API) allows developers to integrate Perplexity’s advanced AI search and synthesis capabilities into their own applications. It provides access to various models, including standard Sonar for fast lookups and Sonar Pro for complex, multi-step research with detailed citations.
API costs are primarily based on token usage, which is divided into input tokens (your prompt and context) and output tokens (the AI’s response). Different models have different per-million-token rates. Additionally, because the API performs live web searches, there is a small per-request fee applied to queries that utilize online search capabilities.
Sonar is the standard model optimized for speed and cost-efficiency, making it ideal for everyday search queries and simple synthesis. Sonar Pro is a more advanced model designed for complex research, offering deeper reasoning, larger context windows, and more comprehensive citations, but it comes at a higher cost per token.
Yes, by default, the Perplexity Sonar models perform live web searches to retrieve up-to-date information and generate responses with inline citations. You can toggle the search functionality on or off depending on your use case, though disabling search may reduce the per-request fee.
To optimize costs, use the standard Sonar model for simple queries instead of Sonar Pro. Keep your prompts concise to minimize input tokens, and use system prompts to format outputs efficiently. Caching frequent responses and batching requests where possible can also significantly reduce your overall monthly spend.
Perplexity occasionally offers trial credits for new API accounts, and Pro subscribers may receive a small monthly API credit. However, for sustained usage, the API is a paid service billed based on your actual token consumption and search requests.
