Returns an OK/CAUTION/AVOID risk verdict for any Base ERC-20 token by analyzing honeypot simulation, taxes, holder concentration, liquidity, LP burn, source verification, and mint/blacklist functions.

## 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-token-risk-verdict-api-c0c3336b
```

Example prompt: Can you run a risk check on the Base token at address 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed and tell me if it's safe to buy — specifically whether it's a honeypot, what the sell tax is, and whether there are any red flags?

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.01) multi-factor risk assessment of a Base ERC-20 token before trading or recommending it. It bundles honeypot simulation, tax analysis, holder concentration, liquidity checks, LP burn verification, and source code validation into a single verdict — saving multiple separate API calls. Ideal for DeFi trading bots, token screening workflows, or any agent that needs a quick safe/unsafe signal on an unknown Base chain token.

## Known failure modes

- Invalid or malformed token address returns an error
- Token not deployed on Base chain returns not-found error
- Very new tokens with no liquidity pool may lack pool data
- Unverified contracts may have limited analysis depth
- Rate limiting or payment failure returns 402 Payment Required

## How this service works

Base ERC-20 risk verdict (OK / CAUTION / AVOID) for $0.01: simulated sell and taxes, top-10 holder share, pool liquidity and age, LP burn, verified source, mint/blacklist functions. Pass a token address.

## Output

A JSON object containing: a top-level verdict string (OK, CAUTION, or AVOID), a human-readable summary, arrays of cautions and red_flags, simulated sell results (buy_tax_pct, sell_tax_pct, is_honeypot), top10_holder_pct, verified_source boolean, pool age in seconds, and the chain identifier.
