## 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-control-risk-screen-verdict-d72630f8
```

Example prompt: Can you run a control-risk screen on this Base token contract — 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — and tell me how many admin-control signals it has and what the overall verdict is?

## When to prefer this

Use this endpoint when you need a quick, structured risk flag on a specific Base network token contract — especially to detect owner-controlled functions (mint, pause, blacklist, fee manipulation) before a trade or listing decision. Prefer this over manual contract reading when you need a machine-readable signal count and headline for automated gating logic. It is not a substitute for a full smart contract audit but is ideal for fast, cheap first-pass screening at $0.02 per call.

## Known failure modes

- Invalid or malformed contract address returns an error — address must be a valid 0x... checksummed Ethereum-style address
- Contract not found on Base network may return empty signals or an error
- Non-token contracts (e.g. multisigs, NFTs) may produce misleading or zero signal counts
- Payment failure via x402 protocol blocks the call before analysis occurs
- Rate limiting or network timeouts on the Cloudflare Worker may return 5xx errors

## How this service works

Pay-per-call utility APIs in USDC on Base: Hebrew calendar and text tools, Shabbat times, Base token control-risk screen and address summary, plus finance arithmetic tools. General information and arithmetic only; not investment, tax or legal advice and not a recommendation to buy, sell or hold anything.

## Output

Returns a JSON object with a plain-English summary of the token's admin-control risk, a short headline (e.g. 'Many admin-control signals found'), and an integer signal_count indicating how many control-risk signals were detected in the contract.
