x402 endpoints offering xAI (Grok) data — resale-authorization audit

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