How this service works
ENS forward/reverse resolution: name->address and address->name. Deterministic, Ed25519-signed.
Output
Returns the resolved Ethereum address for a given ENS name (forward lookup) or the ENS name for a given Ethereum address (reverse lookup), cryptographically signed with Ed25519 for authenticity. On upstream failure, no charge is applied.
Example use cases
Verify wallet identity in transactions
“Before I send funds to vitalik.eth, can you resolve that ENS name to the actual Ethereum address so I can confirm it's correct?”
Find human-readable name for address
“I have this wallet address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 but I don't know who it belongs to. Can you reverse-resolve it to see if there's an ENS name associated with it?”
Batch check ENS domain validity
“I have a list of ENS names that users submitted to my dapp. Can you resolve each one to verify they're all pointing to valid Ethereum addresses?”
Technical details
Endpoint
POSThttps://rpc-ens.hergertsynthora.com/serviceWhen to prefer
Use this endpoint when you need to resolve ENS names to addresses or reverse-resolve addresses to ENS names within an AI agent or automated workflow. Particularly useful when you want a signed, verifiable result and need pay-per-use pricing with no subscription commitment. The first 3 calls per wallet are free, making it low-risk to try. Prefer this over raw RPC calls when you need a simple HTTP POST interface without managing an Ethereum node.
Side effects
- ENS name does not exist or has no resolver set — returns an error indicating unresolvable name
- Address has no reverse ENS record — returns null or empty name
- Upstream ENS node is unreachable — returns failure with no charge applied
- Invalid input format (malformed ENS name or non-checksummed address) — validation error
- Rate limit exceeded beyond the 3 free calls without a wallet header — payment or header required
