x402 endpoints offering Etherscan data — resale-authorization audit

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

Context: Etherscan's API terms restrict redistribution; its paid Pro tier exists for commercial use.

Scan of 23,376 unique x402 endpoints on 2026-07-05, sources: Coinbase Bazaar + GoPlausible registry. Payment counts come from the registries' own published 30-day quality signals. Evidence bullets are automated signature matches — see the methodology for signal definitions, false-positive modes, and the dispute path. If you are on Etherscan's API or trust team and want the full evidence set or a re-verification, open an issue — it's free.
