AI-Powered API for Advanced Web Search, Content Extraction, and Answers

Usage Based

Description

Exa provides developers with powerful API access for interacting with web content. Its core offering is an API that enables sophisticated web searches using various methods, including semantic (neural) search, traditional keyword search, or an automatic mode that selects the best approach. Developers can leverage this API to retrieve specific content from webpages, such as full text, AI-generated highlights, or summaries produced by large language models.

Beyond search and content retrieval, the Exa API can generate direct answers to queries, backed by citations from the source web content. The platform operates primarily on a pay-as-you-go pricing model, charging based on the volume of requests for search, content extraction, and answers, with introductory free credits available. For larger-scale needs, Exa offers custom enterprise plans featuring higher usage limits, tailored configurations, enhanced security options like zero data retention, dedicated support, and volume discounts.
