Two new x402 APIs for AI agents: page-archaeology + agent-cost-calculator

I shipped two new endpoints to the x402 catalog today — both $0.0005 per call, USDC on Base, no signup. What they do /api/page-archaeology?url=<URL> — detect parked / thin / auto-generated pages When an agent cites a source, it needs to know if that source is human-curated or a parked domain.
