## 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 agentshield-token-due-diligence-single-token-dafc755e
```

Example prompt: Before I swap into 0x6b175474e89094c44da98b954eedeac495271d0f (DAI), run a full due diligence check on it — honeypot status, rug pull signals, and any scam mentions you can find on the web.

## When to prefer this

Choose this endpoint when you need a combined on-chain + web scam signal check in a single API call before a DeFi swap or investment decision. Prefer it over separate honeypot checkers or standalone web search because it fuses both signal sources into one verdict with citations. Use it for real-time pre-swap due diligence in automated DeFi agents rather than batch watchlist monitoring (use the batch sibling endpoint for that).

## Known failure modes

- Invalid or malformed contract address returns an error (not a verdict)
- Token not indexed on-chain yet (very new contracts) may return incomplete data
- Web search signals may surface false positives from unrelated mentions
- Rate limits or payment failures return HTTP 402 or 429
- Contract on unsupported chain may return no on-chain data

## How this service works

Is this token a scam? Token due diligence in ONE call ({"address":"0x...","symbol":"SYM"}): on-chain security verdict (honeypot + rug pull signals) fused with a web scam/rug/honeypot mention search, returned as one verdict with sources. For pre-swap due diligence by DeFi agents. Web results are third-party claims — verify before acting.

## Output

A single unified verdict combining on-chain honeypot and rug pull signals with web-scraped scam/rug/honeypot mentions, including a safety grade or verdict label and a list of source URLs or references supporting the conclusion.
