Output

Technical details
Endpoint
POSThttps://twin.unykorn.org/chain/live-balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to check a wallet's native coin and multiple ERC-20 token balances atomically in a single API call, avoiding multiple round-trips. It is ideal for portfolio snapshots, treasury monitoring, or any agent workflow where latency and call cost matter across 10 major EVM chains. Prefer it over individual per-token balance calls or block explorer scraping when you need live, programmatic, pay-per-call access without API key setup.
Side effects
- Invalid or malformed wallet address (not a valid 0x EVM address) — returns validation error
- Invalid ERC-20 contract address in the tokens array — may return zero balance or error for that token
- Unsupported chain name — returns error; only the 10 listed chains are supported
- More than 10 ERC-20 addresses provided — rejected by schema validation
- Chain node unavailability or RPC timeout — returns upstream error
- Payment not settled via x402 — returns 402 Payment Required
