On EmpirioLabs, Perplexity Advanced Deep Research is billed pay as you go: Input $12.00 per 1M prompt tokens; Output $60.00 per 1M generated tokens; Web Search Call $0.012 per call. The live rate card on this page always matches what the API charges.
Yes. Perplexity Advanced Deep Research serves the OpenAI-compatible Chat Completions API, so existing OpenAI SDKs work by pointing base_url at https://api.empiriolabs.ai/v1 and setting the model id to perplexity-advanced-deep-research.
Yes. The EmpirioLabs playground runs Perplexity Advanced Deep Research in the browser with the same parameters the API exposes, so you can test prompts before writing code.
