POST/perplexity/sonar

Sonar — lightweight search + answer

Ask a question and get a written answer with web citations, rather than a list of links to read yourself. Body is OpenAI chat-completions shaped: `model` (required, `sonar`) and `messages`. Returns `choices[0].message.content` as prose, plus `citations` (an array of URL strings) and `search_results[]` with `title`, `url`, `snippet`, `date` and `source`, and a `usage` block. Measured at about 3 seconds. Billed at a flat $0.012 per request. This is the cheapest and fastest of the four Perplexity endpoints — use it for a single factual question. Step up to `post_perplexity_sonar_pro` for multi-part questions, or `post_perplexity_sonar_reasoning_pro` when the answer requires working through steps. If you need results you can iterate over rather than prose, use `post_tavily_search`; `post_exa_answer` answers the same shape of question with semantic retrieval, at $0.08.Price unavailableThe operation requires declared authentication; API keys, bearer tokens and other schemes are not evidence of AEP support.
POST/perplexity/sonar-deep-research

Sonar Deep Research — exhaustive research & comprehensive reports

Commission a report: this endpoint runs many searches and writes a long, cited document. `model` (required, `sonar-deep-research`) and `messages` in; `choices[0].message.content`, `citations`, `search_results[]` and `usage` out, where `usage` also reports `num_search_queries` and `reasoning_tokens`. ⚠️ Budget for the wait: a two-sentence question measured **192 seconds** and returned 86 KB after 10 upstream searches — roughly 60 times slower and 10 times larger than `post_perplexity_sonar`, at the same flat $0.012 per request. Many clients time out well before it answers, so call it only when a report is genuinely the deliverable, and never in a loop. For anything you would read in one sitting, the other three Perplexity endpoints answer in seconds.Price unavailableThe operation requires declared authentication; API keys, bearer tokens and other schemes are not evidence of AEP support.
POST/perplexity/sonar-pro

Sonar Pro — advanced search for complex queries

Ask a question that needs more than one search pass and get a written answer with citations. Same request and response shape as `post_perplexity_sonar` — `model` (required, `sonar-pro`) and `messages` in, `choices[0].message.content`, `citations`, `search_results[]` and `usage` out. Measured at about 10 seconds, roughly three times `sonar`, for the same flat $0.012 per request. Use it for questions with several parts or follow-ups. For a single lookup `sonar` answers in a third of the time at the same price; when the difficulty is reasoning rather than retrieval, `post_perplexity_sonar_reasoning_pro` shows its working.Price unavailableThe operation requires declared authentication; API keys, bearer tokens and other schemes are not evidence of AEP support.
POST/perplexity/sonar-reasoning-pro

Sonar Reasoning Pro — chain-of-thought reasoning with search

Ask a question that has to be worked through, not just looked up, and get a step-by-step answer backed by web search. Same shape as the other Perplexity endpoints — `model` (required, `sonar-reasoning-pro`) and `messages` in; `choices[0].message.content`, `citations`, `search_results[]` and `usage` out. Measured at about 5 seconds, flat $0.012 per request. Use it for comparison, causation and analysis. When the question is simply what is the case, `post_perplexity_sonar` is faster; when you need a long report over many sources rather than an answer, `post_perplexity_sonar_deep_research`.Price unavailableThe operation requires declared authentication; API keys, bearer tokens and other schemes are not evidence of AEP support.
