Fetchium vs Perplexity API: Retrieval vs Inference-Bundled Search

Perplexity is a $20B company (2025) with an excellent consumer AI search product. Their API bundles LLM inference into every call — great if you want AI answers, not suitable if you want raw evidence to feed your own LLM. Fetchium is pure retrieval: you get the evidence, you pick the model, you control the cost.

Different product categories

Perplexity API is an AI answer engine — you ask a question, it searches + reasons + answers. Fetchium is a retrieval API — you ask for evidence, it searches + extracts + cites. They solve different problems. This comparison is most useful if you're deciding whether to use Perplexity as your search layer in an AI application, or to use a retrieval API + your own LLM.

Verified Perplexity API Pricing

Perplexity API pricing has two components: a per-request search fee + token costs. Both vary by model and search depth. There is no free tier.

Request fees (per 1K):

Sonar (low depth)$5/1K
Sonar Pro (medium)$10/1K
Sonar Pro Search (high)$22/1K

Plus token costs:

Sonar input tokens$1/M tokens
Sonar Pro input$3/M tokens
Sonar Pro output$15/M tokens

Source: perplexity.ai/api, March 2026. A typical Sonar query with 2K input + 500 output tokens costs: $5/1K request + $0.002 + $0.0075 = ~$5.01/1K total minimum.
