The Perplexity API gives you cited search answers with one call. It is the cheapest way to add grounded retrieval to a product — and the limits are worth understanding.
Most teams that want grounded answers in their product set out to build a RAG pipeline: crawl, chunk, embed, store, retrieve, rerank, generate. The Perplexity API replaces all of that with one HTTP call. You send a question; you get back an answer with citations. For the first version of a product, it can compress a quarter of work into an afternoon.
The API does not expose chunking, indexing, or reranking knobs. Your corpus must fit in the request context if you want it weighted, and that context is bounded. For a high-volume product where retrieval quality is the moat, you eventually move to your own pipeline — but you've shipped to real users in the meantime.
| Need | Perplexity API | Build your own RAG |
|---|---|---|
| Time to first answer in production | Hours | Weeks |
| Cost at 1M queries/mo | Higher | Lower with optimization |
| Citation reliability | Battle-tested | You own the bugs |
| Domain-specific corpus weight | Limited | Full control |
| Compliance / data residency | Constrained | You decide |
