Perplexity Search API Citations and Brand Mentions Monitoring for AI Search
Perplexity's Search API returns ranked URLs, not brand mentions. Agent API is for cited answers in your app. We rank Promptwatch for the consumer Perplexity UI.
Perplexity Search API citations and brand mentions monitoring are different products. The official Search API returns real-time ranked web results as structured data (title, url, snippet, optional dates), with domain filters, languages, and regions. Perplexity's own docs say: use Search when you need raw results for your own processing. For an LLM-generated answer with citations, use the Agent API.
Neither API is a brand-mention monitor against what a buyer sees in Perplexity. Building a nightly Search-API scrape of your category is engineering, not a GEO dashboard. We rank Promptwatch first for the consumer UI.
Search API vs Agent API vs a monitor
| Product | Returns | Brand mention job? |
|---|---|---|
| Perplexity Search API | Raw ranked results | No. You count domains yourself |
| Perplexity Agent API | Generated answer with citations in your app | No. That is your product, not a buyer session |
| Promptwatch Essential | Observed Perplexity UI on prompts you typed | Yes. Our first-place row |
| Otterly.AI Lite | Mentions; Perplexity in base four | Proof, up to 7-day lag |
| Peec AI | Scores + screenshots | If Perplexity is one of three models |
| Profound Starter | ChatGPT only | No |
max_results on Search accepts 1 to 20 and defaults to 10. Domain allowlists and denylists are documented. Multi-query search exists. That is developer infrastructure. It is not "Perplexity named us on this sales prompt."
Perplexity has 22M+ monthly active users. ChatGPT has 820M+ weekly. Run both columns in a monitor. Do not report Search API rank as mention share.
When the API is the right buy
You are shipping a product that needs ranked links or you are piping results into your own RAG. Buy the API. When the question is "did Perplexity name us, and whose URL did it footnote," buy monitoring.

FAQ
Can I use Search API hits as a citation share?
You can count whether your domain appeared in raw results. That is not the consumer answer. Do not report it as brand visibility.
Does Promptwatch wrap the Search API?
Promptwatch's claim is real UI monitoring, not this API.
Is the Agent API a brand monitor?
No. It generates cited answers inside an app you build.
