Our Verdict
Sonar is the API to pick when answers must be current and sourced. It pairs an LLM with live web search and returns inline citations through an OpenAI-compatible interface you can integrate in an afternoon. Pricing is per request and token, plus a search component on live lookups, so bills track how much retrieved context each answer pulls in. It is deliberately not a general-purpose generator — creative writing and closed-context reasoning are better served elsewhere. For research assistants, news summaries, and fact-checked chat, it is the most direct path.
