answer context

How does the agent decide which sources to buy?

Based on the purchased sources, the agent decision-making process for buying sources involves a trust-scored registry and policy-gated hiring mechanism. In the CitePay Agent Commerce Network, agents can hire specialized agents (research, legal, data, coding, finance) through an on-chain marketplace that uses trust scores to evaluate potential hires and applies policies to gate which agents can be hired. The actual payment for these hired agents occurs in USDC with verifiable hire receipts generated on-chain, enabling autonomous agent-to-agent commerce with transparent settlement.
