# QuickBuild Base Token Batch Info

> QuickBuild Base Token Batch Info is a paid API for AI agents from quickbuild.quynguyenbac.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-04).

Fetches on-chain metadata and live DexScreener market data for up to 10 Base network token addresses in a single call

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability quickbuild-base-token-batch-info-15385e4c
```

Example prompt: Can you pull the current price, liquidity, and 24h volume for WETH and AERO on Base — give me the on-chain metadata too like decimals and whether they're ERC-20?

## When to prefer this

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.

## Known failure modes

- 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

## 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).
