ENS Resolver API
This server connects Claude to the Ethereum Name Service, letting you resolve .eth domains to wallet addresses and do reverse lookups from addresses back to names. It runs on the x402 micropayment protocol, so you'll need to handle per-request pricing. Useful when you're building crypto tools or agents that need to translate human-readable ENS names into addresses for transactions or lookups. The implementation is TypeScript based and accessible via SSE transport at a hosted endpoint. Reach for this when you need ENS resolution without spinning up your own Ethereum node or managing API keys for third-party services.
