Facta is a legal research tool built for AI Agents. It provides a REST API and MCP service, enabling AI systems to retrieve primary sources such as cases, statutes, and regulations when answering legal questions, with verifiable citations included. Its website says it has indexed more than 2.4 million primary sources across 400+ jurisdictions, with an average verification time of under 800ms, but it does not specify the exact countries covered.
Facta is built around an “evidence first, answer second” workflow: legal_find searches for legal sources; legal_verify returns a 0–1 confidence score for candidate sources along with signals such as citation_match and official_source; legal_get_full_text retrieves full text, highlights, and summaries; legal_find_similar finds similar cases; legal_extract_citations extracts references to cases, statutes, and regulations; and legal_deep_research supports multi-query expansion for broader research. Overall, it feels more like retrieval and verification infrastructure for legal AI than a Q&A chatbot designed to replace lawyers.
The free plan costs $0 and includes 5 requests/hour, with access to all research tools and jurisdictions, making it suitable for testing and prototyping. Plus is $20/month and targets solo lawyers and small teams. Pro is $500/year and includes 5 team seats plus higher limits. The documentation provides cURL examples, API Key authentication, 7 endpoints, and MCP configuration, so the integration barrier is relatively low.
Its strengths are its focus on primary sources, original-text links, verification signals, and human review, which can help reduce hallucinations in AI-generated legal answers and complement existing workflows involving Westlaw, Lexis, and similar tools. The limitations are also clear: the terms of service state that results are not guaranteed to be complete, accurate, or up to date; Facta is not a legal service; and its outputs cannot be treated as formal legal advice. The crawled materials did not reveal detailed privacy policy information, Chinese-language support, or payment methods; the examples are mostly in a U.S. law context.
Facta is best suited to legal tech developers, AI Agent teams, solo lawyers, and small law firms that want to build citable, traceable legal research workflows. Access from mainland China is unknown, and payment methods are not disclosed. If access is unreliable or its U.S. law coverage does not match your needs, alternatives or complementary tools include Westlaw, Lexis, Cornell LII, vLex, and CoCounsel.
