The recommended first paid call is shadowgraph_global_snapshot / hidden_chain at $0.50. The paid endpoint returns HTTP 402 with a WWW-Authenticate: Payment challenge before settlement. Coverage includes US/SEC EDGAR, EU/TED, global markets, infrastructure and news, with Türkiye as a regional pack. Outputs are probabilistic intelligence; inferred graph edges, statistical lead/lag and candidate commercial leads are not proof of causation, contracts or guaranteed returns."
