Technical details
Endpoint
GEThttps://api.x402node.dev/chain/ensWhen to prefer
Use this endpoint when you need to translate between human-readable ENS names (e.g. alice.eth) and raw Ethereum addresses, or vice versa, on Ethereum mainnet. Prefer this over general blockchain APIs when ENS resolution is the specific task and you want a lightweight, pay-per-call solution without managing your own RPC or ENS SDK.
Side effects
- ENS name has no resolver set — returns null or not-found response
- Address has no primary ENS name set — reverse resolution returns empty
- Invalid ENS name format — returns validation error
- Invalid Ethereum address format — returns error
- ENS name expired or not registered — returns not-found
- Network/RPC timeout contacting Ethereum mainnet
