## 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-risk-score-5036825d
```

Example prompt: Can you check the risk level of the token at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — I want to know if it's safe before I interact with it?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call risk score for a specific ERC-20 token on the Base network without needing to set up an account or API key. It is ideal for AI agents making autonomous DeFi decisions, pre-trade checks, or fraud screening where micropayment-based access (via x402/USDC) is acceptable. Prefer this over manual on-chain analysis when you need a structured, scored output with human-readable risk reasons rather than raw blockchain data.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Non-Base (chain ID != 8453) addresses may not be supported
- Rate limiting or x402 payment failure blocks the request
- Unverified or newly deployed contracts may have limited signal data
- Network congestion on Base may slow on-chain data retrieval

## 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

A JSON object containing the token symbol, contract address, chain ID (8453 for Base), a numeric risk score (integer), a risk level string (e.g. 'low', 'medium', 'high'), an array of human-readable reasons explaining the score with point adjustments, an on-chain signals object, and a disclaimer noting results are informational only.
