# Base Onchain Batch ERC-20 Safety Scanner

> Base Onchain Batch ERC-20 Safety Scanner is a paid API for AI agents from x402-data-api.bodhinindustries.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Batch-scans up to 20 Base ERC-20 token addresses live from on-chain data, returning honeypot verdicts, risk flags, sellability checks, and safety scores with no third-party data dependencies.

## 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 base-onchain-batch-erc-20-safety-scanner-89c02cdf
```

Example prompt: Can you safety-scan these Base ERC-20 tokens for honeypots and risk flags before I swap into them: 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913, 0x4200000000000000000000000000000000000006, 0x50c5725949a6f0c72e6c4a641f24049a917db0cb?

## When to prefer this

Choose this endpoint when you need trustless, live on-chain ERC-20 safety analysis on Base without relying on any third-party reputation databases or cached data. Ideal for AI agents making DeFi decisions, pre-swap token vetting, or batch-triaging a watchlist of tokens for honeypot and rug-pull risk. Prefer this over generic token scanners when data provenance and independence from third-party feeds is critical.

## Known failure modes

- Invalid or non-ERC-20 address: token appears in skipped[] with reason field explaining why
- More than 20 addresses requested: excess tokens may be skipped or request rejected
- Network/RPC failure on Base: may return partial results or error response
- Malformed comma-separated list: individual bad entries reported in skipped[], valid ones still processed
- Token with no on-chain liquidity: verdict returned as 'unknown'

## How this service works

Self-computed Base onchain toolkit for AI agents: ERC-20 safety scan, manipulation-resistant TWAP price oracle, gas/fee oracle, calldata decoder, token/address/contract intel, wallet approval-risk audit, and batch token triage — all computed live from raw Base chain, no third-party data.

## Output

Returns a per-token verdict (likely_ok, caution, honeypot, or unknown), sellability boolean, array of risk flags, and isHoneypot flag for each address — plus metadata: current Base block height, ISO-8601 timestamp, count of scanned vs skipped addresses, and reasons for any skipped entries. thirdPartyDataUsed is always false, confirming all data is computed live from Base chain.
