## 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 xx402-base-token-batch-diligence-api-26fe1e4c
```

Example prompt: Can you run a batch token diligence check on 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on the Base network — screen it for risk, liquidity, and holder patterns using the last 100 blocks, and tell me whether it belongs in the buy, review, or avoid bucket?

## When to prefer this

Choose this endpoint when an AI agent needs rapid, structured on-chain due-diligence for up to 3 Base network ERC20 tokens before executing a trade, rebalance, or investment decision. It is purpose-built for autonomous DeFi agents that need risk classification (buy/review/avoid buckets), liquidity signals, and holder analysis in a single call paid via x402 microtransaction. Prefer this over generic blockchain explorers or manual on-chain queries when you need a pre-packaged risk verdict with decision evidence rather than raw chain data.

## Known failure modes

- Invalid or non-existent token address returns empty or error results
- Exceeding limit of 3 token addresses may result in truncation or rejection
- window_blocks below 100 or above 1000 returns a validation error
- Payment not accepted or x402 payment failure returns 402 with no data
- Newly deployed tokens with insufficient on-chain history may return sparse risk signals
- Rate limiting or provider downtime may return 5xx errors

## How this service works

Paid Base token, wallet, DeFi, chain-read, x402 buyer/seller discovery, and specialized Bitcoin 15-minute Up/Down prediction-market data packets for autonomous agents and risk tools.

## Output

Returns a structured JSON object including: a summary, batch decision, priority queue of tokens, best candidates, risk breakdown per token, a review queue, an avoid queue, high-risk token list, manual review tokens, risk level counts, bucket counts, liquidity/flow/holder source statuses, buyer next action guidance, next paid call recommendations, and a not-financial-advice disclaimer.
