  "description": "Before an AI agent pays an unfamiliar counterparty, Fidren returns what payment action the observed evidence supports, how much exposure that evidence supports for the amount actually requested, and why. Same counterparty, same evidence, a different requested amount: potentially a different payment action. The amount is an input to the decision, not a filter applied to a fixed score. Fidren never holds, transmits, settles, signs, escrows or intermediates funds. It returns an advisory decision; the caller\u2019s own infrastructure enforces it.",
