How this service works
OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana, Algorand and Polygon via x402.
Output
A JSON object containing: native ETH balance, balances for up to 20 ERC-20 tokens (defaulting to USDC, WETH, cbBTC), transaction count (nonce), a heuristic wallet_class label (one of: ghost, newcomer, steady, degen, whale), and reverse ENS name if set for the address on Base.
Example use cases
DeFi credit check before lending
“Before I approve this loan request, check the Base wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — what are its ETH, USDC, and cbBTC balances, how many transactions has it made, and is it classified as a whale or newcomer?”
Whale alert monitoring
“I want to know if the address 0xAbCd1234...5678 on Base is a whale — pull its full token balances including WETH and cbBTC, its transaction count, and its wallet class right now.”
Bot detection for airdrop eligibility
“Check 0x1234abcd...ef on Base: is this a ghost or a real active wallet? I need its tx count, ETH balance, and wallet class to decide if it qualifies for the airdrop.”
Technical details
Endpoint
GEThttps://api.losbeto.xyz/chain-balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single enriched snapshot of a Base wallet — combining raw balances, activity level, and a pre-computed wallet classification — rather than making separate RPC calls for each data type. Ideal for DeFi agents doing credit profiling, airdrop eligibility checks, whale detection, or onboarding KYC-lite flows where wallet behavior matters as much as raw balance.
Side effects
- Invalid or malformed address returns an error — must be a valid EVM 0x address
- Unsupported network (non-Base chain) may return empty or incorrect results
- More than 20 tokens requested exceeds the batch limit
- Unregistered ENS returns null for reverse ENS field
- RPC timeout on Base may cause delayed or failed response
- Invalid token contract addresses in the tokens parameter return zero balances
