Its core product is a search API with a large independent index, where queries can be semantic, keyword-based or configured for latency versus depth, and results come back with clean text, highlights and grounded citations rather than noisy page markup. On top of search, Exa offers a contents endpoint for extracting page content, an agent endpoint and websets for finding sets of entities that match a description, along with monitors and integrations such as an MCP server. Search runs in tiers (roughly fast, balanced and deep) so developers can trade latency against research quality, and the same API supports verticals like code, finance, companies, people and news. Exa markets itself to teams building AI assistants, coding agents, GTM and sales tooling, recruiting and finance research, and reports very large indexed document volumes and heavy token savings from its highlight-based content extraction. The company emphasises enterprise readiness with SOC 2 Type II, GDPR, CCPA and HIPAA-aligned controls and zero data retention options. **Pricing & Plans:** Freemium: free API usage to start plus usage-based pricing, with custom enterprise plans available. Confirm current rates on the pricing page. - **Semantic and keyword search API:** Run natural-language or keyword queries against a large independent web index with filters for domain, date and category. - **Token-efficient contents:** Return cleaned page text and AI-extracted highlights so agents receive the most relevant excerpts instead of entire pages. - **Agent and deep research endpoints:** Choose fast, balanced or deep search modes so an assistant can answer instantly or run longer grounded research. - **Structured enrichment:** Extract structured outputs such as company details, people and other entities for list building and data pipelines. - **Crawling and integrations:** Crawl URLs, track changes with monitors, and connect Exa to agents and IDEs through an MCP server and SDKs. **Strengths:** Purpose-built for AI agents, not retrofitted from consumer search; Token-efficient highlights reduce context cost meaningfully for LLM applications; Structured enrichment plus search in one platform covers many pipelines; Strong compliance posture including SOC 2 Type II and zero data retention options **Limitations:** Pricing is usage-based and requires monitoring to control spend at scale; Requires developer effort since it is primarily an API rather than a point-and-click app; Access to the deepest research modes costs more than fast lookups [Profile (Markdown)](https://openaitools.app/tool/exa-ai.md) ## StackRef StackRef is an independent consulting practice run by Keith McDuffee, a CISSP-certified cloud architect with more than 20 years across infrastructure, DevOps, and security, currently also a Senior Director of DevOps and Application Security. The consulting side provides hands-on help designing, securing, and optimizing cloud environments on AWS, GCP, and Azure, with an emphasis on being precise and clear about requirements rather than over-charging or over-complicating. Alongside consulting, StackRef offers its own designed, self-hosted, end-to-end internal hackathon manager. This product supports the hackathon lifecycle with features such as sandbox environments, AI-assisted scoring, and team collaboration, making it useful for organizations that want to run internal innovation events on their own infrastructure rather than a third-party SaaS.
