## 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 token-signal-base-token-safety-risk-signals-09e1d09b
```

Example prompt: Before I buy any of this token, can you run a safety check on contract address 0x1234abcd...5678 on Base and tell me if there are any red flags around holder concentration, liquidity, or contract risk?

## When to prefer this

Choose this endpoint when an agent needs a quick, low-cost ($0.002 USDC) token safety pre-check on the Base network before executing a buy or approve action. It is ideal for automated DeFi agents that need lightweight heuristic signals — not deep forensic audits — covering holder concentration, liquidity, market activity, and contract risk in a single call. Prefer it over full audit services when speed and cost matter more than exhaustive analysis.

## Known failure modes

- Invalid or malformed contract address returns an error or empty result
- Token not found on Base chain (unsupported chain or wrong address) returns no data
- Rate limiting or payment failure (x402) if USDC payment is not processed correctly
- Stale or missing on-chain data for very new or obscure tokens may yield incomplete signals

## How this service works

Token Signal: low-cost Base token safety, liquidity concentration, holder concentration, market activity, and basic contract-risk signals for agents checking tokens before buying or approving.

## Output

Returns structured risk signals for the queried token contract, including safety score, liquidity concentration, holder concentration, market activity indicators, and basic contract-risk flags — enabling agents to make informed go/no-go decisions before buying or approving a token.
