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
Returns a JSON object containing native ETH balance, up to 20 ERC-20 token balances (defaults to USDC, WETH, cbBTC), transaction count (nonce), a heuristic wallet_class label (ghost/newcomer/steady/degen/whale), and reverse ENS name if set — all fetched via batched eth_call on Base.
Example use cases
DeFi portfolio snapshot for agent
“Can you pull the full token portfolio for wallet 0xAbCd1234...5678 on Base — I want to see ETH, USDC, WETH and cbBTC balances and whether it's classified as a whale or degen.”
Wallet activity audit before airdrop
“I need to know the transaction count and wallet class for 0x1234abcd...ef56 — I want to make sure it's not a ghost wallet before I include it in the airdrop list.”
ENS resolution with balance context
“Look up the reverse ENS name and current ETH balance for wallet address 0xDead...Beef on Base so I can display it in our portfolio dashboard.”
Technical details
Endpoint
GEThttps://markets.losbeto.xyz/chain-balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, keyless, pay-per-call wallet balance snapshot on Base with built-in wallet classification and ENS resolution — especially useful for AI agents that need on-chain context without managing API subscriptions. Prefer over alternatives when you want batched multi-token balances plus intelligence metadata (wallet class, nonce, ENS) in a single call, and when paying with USDC via x402 is acceptable.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported chain or Solana address may not resolve on Base
- Token list exceeding 20 tokens may be truncated or rejected
- Wallet with no on-chain activity returns zero balances and ghost classification
- Payment failure via x402 results in 402 response before data is returned
- ENS not set returns null for reverse ENS field
