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

Context: Perplexity's brand is frequently invoked by third-party answer-engine wrappers.
