ENS lookup API prices: forward, reverse and verified names
Published 2026-10-24 · Updated 2026-10-24
The 2026-10-24 public listing snapshot contains 55 ENS resolution offers on 47 hosts: lowest USD 0.001, median USD 0.005, highest USD 0.1 per listed lookup unit. Tanod costs USD 0.002 per forward or reverse lookup. These are advertised prices, not tested quality or live quotes.
Forward resolution maps a name to an address. Reverse resolution reads a name claimed by an address. A verified primary name additionally resolves that name forward and compares the resulting address with the original. A reverse record alone is not proof of identity.

“Not stated” means the listing does not explicitly promise the feature; it does not mean unsupported. Capabilities are seller descriptions, not delivery tests. Read the current payment requirements before paying. Batch-capable listings can charge per name or per address, so a batch is not assumed to cost one lookup.
Free alternative: a public RPC plus a library
Use a no-key public Ethereum RPC such as PublicNode Ethereum with an open-source (MIT) library such as viem or ethers. Ordinary onchain reads do not require a wallet, a signature or an onchain transaction fee. The RPC operator can rate-limit or change access; “free” is not an availability guarantee.
With viem, normalize a name before getEnsAddress. For reverse names, use getEnsName and resolve its result forward with getEnsAddress; compare addresses before displaying it as verified. Unicode normalization, wildcard resolvers and CCIP-Read support vary by library and configuration. Offchain resolvers may cause additional HTTP requests. Do not treat a displayed name as a safe payment destination.
Which lookup do you need?
Tanod's ENS resolve endpoint accepts one ASCII name or address on Ethereum mainnet. Reverse responses include verified; a name may still be present when that flag is false. For text records, contenthash and other-chain addresses, use the separate ENS records endpoint at USD 0.003 per call, not the lookup rate above.
Sources and comparison limits
Prices and feature statements come from the CDP Bazaar and PayAI discovery feed fetched 2026-10-24. Only public USDC-priced name/address resolution offers are included. Duplicate URLs are combined at the lowest listed USDC price; repeated paths with the same host, description and price count once. Non-resolution tools and templated bulk catalogs are excluded. Tanod is not included in the third-party summary. ENS records, name availability and namehash utilities are different work and are not pooled into these statistics.
