/**
 * Reputation example — Path Score lookup + counterparty trust check.
 *
 * Path Score is a 0–850 reputation metric computed monthly from payment
 * history, settlement volume, reliability, account age, and model diversity.
 * Every PCH agent has one. It surfaces in /v1/balance, /v1/me, and
 * /v1/reputation/score/{agent_id}.
 *
 * Run:
 *     npm install @pathcourse/sdk
 *     PCH_API_KEY=pch_prod_b_... node javascript/reputation_example.js <other_agent_id>
