## Recommendation: Linkup For a product that can't tolerate hallucinated answers, **Linkup** is my pick. Its decisive advantage is *verifiable* factuality, not just marketing: it holds SOTA on OpenAI's SimpleQA (92% F-score among sub-second search APIs; Research tops SealQA-0), and — critically — it ships an **open-source eval harness** (`LinkupPlatform/eval-simpleQA`) so those numbers are independently reproducible. Its `sourcedAnswer` mode returns an answer *with* inline citations and the supporting source URLs, and it also returns ranked raw sources, so your GPT-4o agent can ground on and cite primary sources rather than trusting a black-box answer. Simple REST + API key fits the repo's existing `fetch`-based tool pattern in `lib/ai/tools/financial-tools.ts`. ## Main alternatives considered | Provider | Strength | Why not chosen | |---|---|---| | **Exa** | Best neural/semantic discovery; high third-party SimpleQA (~94.9% on its slow *Research* API); `/answer` + highlights | Optimized for conceptual discovery over short-form factuality; fast-search citation guarantees thinner than Linkup's reproducible numbers | | **Perplexity Sonar** | Returns `citations`+`search_results`; **SEC
