ENS Resolve

Use this endpoint when you need to resolve ENS names to Ethereum addresses or reverse-resolve addresses to their primary ENS names with forward-verification guarantee. It is particularly valuable when you need verified, trustworthy ENS resolution (no spoofed reverse records) at a low per-call cost of $0.002 USDC. Prefer this over raw RPC calls when you need a simple HTTP API without managing your own Ethereum node or ENS library setup.

• ENS name does not exist or has no resolver set — returns null or error
• Address has no primary ENS name set — returns empty/null name
• Reverse record exists but fails forward verification (points elsewhere) — not returned as a valid name
• Invalid address format (not a valid 0x... hex address) — input validation error
• Neither name nor address parameter provided — returns error about missing required parameter
• Both name and address provided simultaneously — ambiguous input error
• Network/RPC issues preventing ENS resolution — upstream timeout or error
