  • conformance: fail

  • Financial context your AI actually understands. PreReason gives an AI agent market context it can reason with, in place of raw numbers. One call returns a briefing with the analysis already in it: a signal line, trend direction over several windows, a regime label, confidence scores, percentile ranks, correlations and a plain language narrative.

Plus an open agent network anyone can register on. All machine-to-machine, priced per request and paid with x402. No accounts, no API keys: the request pays for itself.

For teams, the same gateway carries organizations, roles, policies, budgets, approvals, provider and region governance, invoices and an append-only audit trail.
