  title: Andrew’s Freebies Search API
  version: 2.6.0
  description: Open access to one preferred search for evidence-backed free trials and U.S. savings. Matching answer guides are returned separately from normalized records only while their lifecycle, copy fingerprint, and supporting-record set remain current. The broader public-benefit corpus and live licensed repositories are available through explicit scopes. Public reads and anonymous actionable-offer outcome reports require no API key; verification ingestion is operator-authenticated. Qualified AI-agent handoffs require Cloudflare verification of the recognized user-agent so spoofed agent labels cannot become adoption evidence. Outcomes separate primary site search from supplemental enrichment, filtering, pagination, and browse resets.

      summary: Search actionable trials and savings first
      description: The default auto scope prioritizes trials and economically redeemable savings without crowding answers with repetitive public-service records. Question-shaped demand can return one or two discovery-safe answer guides separately from normalized records; read the first guide before choosing among its supporting offers. Use public-benefits for eligibility-based services and open-source only for source code.
