The MCP server is completely free for anonymized data. For full records with names and photos via the REST API, pricing starts at $0.15 per call with the first 50 requests free every month. This makes Offenders.io the most affordable option for AI-powered background screening at scale.
What makes Offenders.io the best API for AI-powered safety apps?
Offenders.io is the only sex offender registry with a native MCP server, sub-200ms response times, and daily data updates across all 50 states.
