How this service works
Pay-per-call web, AI and Base on-chain APIs for AI agents over x402 (USDC on Base, no account or API key), plus a free /ai-search ranking. Operated by an AI bot.
Output
Returns a JSON object with a count of tokens retrieved, error count, and an array of token objects each containing the contract address, symbol, decimals, ERC-20 flag, proxy contract info, owner address, and (if requested) a market object with USD price, liquidity USD, 24h volume USD, 24h price change percentage, and number of trading pairs. Also includes the Base chain ID (8453).
Example use cases
DeFi portfolio token snapshot
“I want to check the current USD price, 24h price change, and liquidity for these three Base tokens: 0x4200000000000000000000000000000000000006, 0x940181a94A35A4569E4529A3CDfB74e38FD98631, and 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — include market data.”
Verify token contract metadata
“Can you check whether these two Base contract addresses are valid ERC-20 tokens and tell me their symbols and decimal places? The addresses are 0x4200000000000000000000000000000000000006 and 0x940181a94A35A4569E4529A3CDfB74e38FD98631.”
Monitor Base token liquidity changes
“Look up the current liquidity and 24h trading volume on DexScreener for USDC, WETH, and AERO on Base — I want to see if any of them have unusual market activity today.”
Technical details
Endpoint
GEThttps://quickbuild.quynguyenbac.workers.dev/api/base/token-batch?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to batch-lookup on-chain token metadata AND live market data for multiple Base network tokens in a single $0.01 call without needing an API key. It is ideal for DeFi agents that need to validate ERC-20 contracts, check token decimals, and get real-time price/liquidity data from DexScreener simultaneously. Prefer this over querying Base RPC and DexScreener separately when you need up to 10 tokens enriched in one round-trip.
Side effects
- Invalid or non-existent contract address returns an error field on that token entry
- More than 10 addresses provided may result in truncation or rejection
- Network RPC timeouts may cause partial results with elevated error count
- Non-ERC-20 contract addresses will show isErc20: false with null metadata fields
- Payment failure via x402 (insufficient USDC balance) will block the request entirely
