x402 policy:

Single-episode HTML / Markdown / JSON are free. Bulk exports under /api/export/* require x402 payment per request, priced at $0.03 per access. A payment grants only that single access and does not create a persistent reading period. See https://soublock.com/.well-known/x402 for the full machine-readable policy.
