A shareable research session with paid citation receipts is a multi-turn AI research interface where each follow-up question inherits context from previous Q&A pairs, with every turn automatically paying creators in USDC via Circle Gateway x402 nanopayments. Each citation generates a verifiable on-chain receipt showing the exact payment, content integrity proof (SHA-256 hash), and settlement evidence. Sessions are shareable with a complete receipt trail that transparently documents what was paid, to whom, and why—enabling both the researcher and creators to audit the full citation economy transaction history. The system enforces spend policies (max price per citation, relevance thresholds, session caps) and batches payments to sub-cent values without per-transaction gas overhead, making continuous creator compensation economically viable at scale.
