AI semantic web search API for developers

FreemiumVerifiedSummarizationAnalyticsResearch AssistantCitation GeneratorLiterature ReviewData AnalysisAI AssistantNatural Language Processing

Provides an AI‑driven semantic search API that interprets natural language queries and returns ranked results from the open web or a developer‑supplied document set. The service builds vector embeddings for each query and index entry, enabling meaning‑based matching rather than keyword overlap. Features include intent detection, relevance tuning knobs, multi‑language support for over 30 languages, real‑time indexing of newly added content, and customizable ranking callbacks. Responses are delivered in JSON with snippets, confidence scores, and source URLs. Developers building site search, e‑commerce catalogs, or internal knowledge bases use the API to replace brittle keyword filters with intent‑aware results. Typical use cases include embedding search bars in SaaS dashboards, powering chatbot retrieval layers, and surfacing relevant policy documents for compliance teams. The free tier grants up to 5,000 queries per month and basic analytics; paid upgrades raise limits, add SLA guarantees, and unlock priority processing. Billing is monthly and tied to request volume, so costs scale with traffic. Compared with traditional search services like Algolia or Elasticsearch, Exa Search adds AI semantics without requiring complex query DSLs. Integration is straightforward: a REST endpoint accepts POSTed JSON, and SDKs for JavaScript, Python, and Go handle token generation and response parsing. Security features include API‑key authentication, IP whitelisting, and GDPR‑compatible data handling. A built‑in dashboard shows query latency, error rates, and usage trends, helping teams monitor performance. Because the engine operates on vector similarity, it excels at finding related concepts even when exact terms differ.
