answer context
what is the purpose of citation?
Based on the purchased sources, citation serves multiple interconnected purposes: it enables attribution and payment to creators whose work is reused in answers, it ensures answers are grounded in verifiable sources, and it creates an auditable record linking reasoning to the sources that support it. Specifically, source payments should be tiny, automatic, visible to the creator, and tied to the answer that reused the work. Additionally, answer agents draft answers grounded strictly in purchased content and self-critique to drop any claim a purchased source does not support. Every step of source buying and reasoning is recorded and hashed into the answer, so the reasoning and the payments are auditable together.
Open answer evidencex402 Settlement Schemes on Arc
Payments Protocol Notes / 0.001300 USDC Shows citation as a payment trigger: HTTP 402 turns citation into a real settlement step. Demonstrates purpose in practice.Seed/demo content from Payments Protocol Notes. Title: x402 Settlement Schemes on Arc. Excerpt: x402 turns HTTP 402 into a real payment step: a resource returns payment requirements, the client signs an EIP-3009 USDC authorization, and the server settles it. The 'exact' scheme settles that authorization directly on Arc as a single USDC transfer, so the reader's debit is a verifiable on-chain transaction. The Circle Gateway-batched scheme instead pools many signed authorizations for gasless sub-cent settlement, referenced by a Gateway payment id rather than one Arc tx.
