How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns a list of token balances associated with the queried wallet address on the X Layer network. Each entry typically includes the token contract address, token symbol or name, raw and/or formatted balance amounts, and decimals. If contract addresses are specified, results are filtered to only those tokens.
Example use cases
DeFi portfolio audit on X Layer
“What tokens does the wallet 0xDeAdBeEf0000000000000000000000000000cafe hold on X Layer? I want to see everything in that address.”
Verify token receipt on X Layer
“Did the wallet 0x1234567890abcdef1234567890abcdef12345678 receive any of the token at contract 0xaabbccdd11223344556677889900aabbccddee00 on X Layer yet?”
Filter specific holdings for compliance
“Check which of these three token contracts — 0xAAA..., 0xBBB..., 0xCCC... — the wallet 0xUser1234... actually holds a balance in on X Layer.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/xlayer/token/balancesWhen to prefer
Use this endpoint when you need fast, pay-per-call token balance lookups specifically on the X Layer (OKX) network without maintaining your own RPC node. Prefer it over general-purpose blockchain RPCs when you want a simple REST API interface rather than raw JSON-RPC calls, and when querying a portfolio of specific tokens for a given wallet. It is ideal for lightweight agents that need on-demand balance checks without subscription overhead.
Side effects
- Invalid or malformed owner wallet address returns an error or empty result
- Unknown contract addresses return zero balance or are omitted
- X Layer network congestion or RPC unavailability may cause timeouts
- Non-checksum Ethereum addresses may be rejected
- Empty contractAddresses array may return all tokens or require at least one entry depending on implementation
