## 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-new-pool-risk-scorer-adbe059e
```

Example prompt: Can you check the risk score for this new liquidity pool on Base — the token contract is 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed? I want to know if it's flagged as high risk before I interact with it.

## When to prefer this

Use this endpoint when you need a fast, structured risk score specifically for a newly created liquidity pool on the Base network (eip155:8453), given a token contract address. Prefer this over generic token scanners when the pool is freshly launched and you need Base-specific risk flags before executing a swap or providing liquidity.

## Known failure modes

- Invalid or malformed token address (not matching ^0x[a-fA-F0-9]{40}$) returns a validation error
- Token address not found on Base network returns empty or null assessment
- Pool does not exist yet for the token returns no pool data
- Payment not included or insufficient USDC results in 402 Payment Required
- Network timeout on Cloudflare Worker edge returns 503 or gateway error

## How this service works

Machine-payable service intelligence for discovering, verifying, and monitoring identity, risk, authorization, execution-preflight, and evidence APIs before autonomous agents spend.

## Output

A JSON object containing the network identifier (eip155:8453), product name (base-new-pool-risk), and an assessment object with risk_score (numeric), risk_level (e.g. 'low', 'medium', 'high'), and flags array listing any detected risk signals for the queried token's newest pool.
