How this service works
Pay-per-call x402 APIs for AI agents: OpenAI-compatible LLM chat, perp funding and arbitrage spreads, crypto prices, gas, FX, Solana SPL mint audit, token price by contract, x402 delivery-receipt verification, web search, clean page extraction, batch tools and deterministic code-security scanning. USDC on Base or Solana, no signup, no API key, from $0.0001 a call.
Output
Returns a JSON object containing a results array of up to 10 items, each with the wallet address, token contract address, network, raw balance as a number, human-readable balance string (formatted with token decimals), token decimals, and a success flag. Also includes a count of results, the product identifier, and the USD price charged for the call.
Example use cases
DeFi portfolio balance snapshot
“Fetch the USDC and USDT balances for my five wallet addresses on Base all at once — wallet addresses are 0xAAA...1, 0xBBB...2, 0xCCC...3, 0xDDD...4, 0xEEE...5 and the token contracts are 0xUSDC and 0xUSDT on Base.”
Airdrop eligibility token check
“Before running our airdrop, check whether these 8 wallets already hold our ERC-20 token (contract 0xTKN...abc) on Ethereum — here are the wallet addresses: 0x1...0x8.”
Smart contract funding verification
“Verify that wallet 0xPAYER...xyz holds at least enough WETH (0xC02aa...token) on Ethereum to cover our transaction — can you pull the current token balance?”
Technical details
Endpoint
GEThttps://scanpay-edge.alextaghiashvili.workers.dev/api/v1/token-balance-batch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to query ERC-20 token balances for multiple wallet/token pairs on Base or Ethereum in a single batched call, avoiding multiple round-trips. It is ideal for portfolio snapshots, airdrop eligibility checks, funding verifications, or any workflow needing bulk balance data without running your own node. Prefer this over single-balance lookups when you have 2–10 pairs to check simultaneously, and over full blockchain indexers when you only need current balances rather than historical data.
Side effects
- Invalid or malformed wallet/token address returns an error entry with ok:false for that pair
- Unsupported network (not Base or Ethereum) may return an error or empty result
- More than 10 wallet/token pairs submitted may be rejected or truncated
- RPC node unavailability may cause transient eth_call failures
- Token contract that is not a standard ERC-20 may return unexpected results or fail balanceOf call
- Rate limiting or payment failure may block the request entirely
