Turn a .eth name into an address, or an address into its primary .eth name -- one endpoint, auto-detects which direction based on the input. Ethereum mainnet only (ENS has no separate Base deployment).
# 1. Ask the endpoint what it costs (no payment, no wallet needed): curl -i -X POST 'https://chainsscope.duckdns.org/tools/ens-resolve' # -> HTTP/1.1 402 Payment Required # the response carries the price, asset and pay-to address. # 2. Pay and retry with any x402 client: npx x402-fetch -X POST 'https://chainsscope.duckdns.org/tools/ens-resolve'
Endpoint: https://chainsscope.duckdns.org/tools/ens-resolve. Operated by chainsscope.duckdns.org, not by Animica. Price and availability were correct at the last probe on 2026-09-02 and are set by the operator, who may change them.
