Fully closed search-grounded API; no weights, source, or self-host path.

• https://docs.perplexity.ai/ recorded 2026-08-13

  Sonar, Search API, Embeddings API and Agent API documented as hosted endpoints with token and per-request pricing. No weights, source release, self-host or on-premise option documented anywhere.

Perplexity publishes no standalone request or developer count for the Sonar API, though its own documentation confirms the API is a core developer surface. Independent reporting puts the parent consumer app at mass scale, but that figure covers app usage rather than API traffic, so the API's traction here is inferred from that platform scale rather than measured directly.

• https://docs.perplexity.ai/ recorded 2026-08-13

  Sonar, Search API, Embeddings API and Agent API documented as first-class developer surfaces. No request, developer or customer figure appears anywhere in the docs.

• https://www.perplexity.ai/api-platform recorded 2026-06-04

  Vendor API-platform page positioning Sonar for developers. The host answers HTTP 403 to the fetcher, so this source keeps its earlier access date.

Perplexity's Agent API composes a cited answer directly, and the same platform exposes raw ranked results too, combining discovery with a synthesized response. That marks the frontier of the category; other composed-answer products are compared against Perplexity or against Grounding with Bing Search.

  The Available APIs list: "Agent API - Get web-grounded answers with built-in citations in one call" and "Search API - Get raw, ranked web search results with advanced filtering and real-time data", both under the Perplexity API.
