How this service works
Resolve a Basename (name.base.eth on Base) to its address, or an address to its verified primary Basename (reverse record checked forward).
Output
Returns a JSON object with three fields: 'red' (the network, e.g. 'base'), 'basename' (the resolved .base.eth name, or null), and 'direccion' (the resolved 0x wallet address, or null). Both forward (name→address) and reverse (address→name) lookups are supported; the reverse result is verified to confirm the forward record matches.
Example use cases
Paying someone by Basename
“I want to send crypto to alice.base.eth — can you look up what 0x address that basename resolves to so I can send the payment to the right place?”
Verifying a user's identity
“Someone told me their Base wallet is 0x2211d1D0020DAEA8039E46Cf1367962070d77DA9 and their basename is jesse.base.eth — can you check whether that address actually has jesse.base.eth as its verified primary basename?”
Displaying human-readable sender name
“I received a transaction from 0xAbC123...in my app and want to show the sender's name instead of the raw address — can you do a reverse lookup and find if this wallet has a .base.eth basename?”
Technical details
Endpoint
POSThttps://api.vextorium.com/basename-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve Base blockchain usernames (.base.eth) to wallet addresses or vice versa, specifically on the Base (Coinbase L2) network. Prefer this over generic ENS resolvers when dealing exclusively with Basename identities rather than mainnet .eth names. Ideal for payment flows, identity verification, and user-facing display of wallet names in Base ecosystem applications.
Side effects
- Basename not registered or expired — returns null for address field
- Address has no verified primary Basename set — returns null for basename field
- Invalid input format (neither a valid .base.eth name nor a 0x address) — likely returns an error or null results
- Name registered but no forward-confirmed reverse record — reverse lookup returns null to prevent spoofing
- Network issues reaching Base RPC — may return an error or timeout
