x402 endpoints offering Yahoo Finance data — resale-authorization audit

8 machine-payable (x402) endpoints in the public discovery registries exhibit reseller signatures referencing Yahoo Finance while hosted off Yahoo Finance's own domains. Resale-authorization status: unknown — suspected unauthorized resale, verification recommended. Any of these endpoints may hold a legitimate redistribution license.

Context: Yahoo Finance has no official public API; third-party “Yahoo Finance APIs” are typically scraper-based.
