> GadgetHumans Token Safety Checker is a paid API for AI agents from api.gadgethumans.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

## 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 gadgethumans-token-safety-checker-8d44da5e
```

Example prompt: Before I swap into this token, can you check if the Base contract address 0x4ed4e862860bed51a9570b96d89af5e1b0efefed is safe to trade?

## When to prefer this

Use this endpoint when an AI agent needs a quick, low-cost ($0.02) safety gate before executing a token swap, purchase, or routing decision on the Base network. Prefer this over manual contract inspection when operating autonomously in DeFi workflows where rug pull or honeypot risk is a concern. Best suited for single-contract lookups in real-time trading pipelines.

## Known failure modes

- Invalid or malformed contract address (not 0x + 40 hex chars) returns an error
- Contract address not found on Base mainnet returns a failure or unknown verdict
- Network timeout or upstream data unavailability may return a non-ok response
- Newly deployed contracts with insufficient on-chain data may produce inconclusive results

## Output

Returns a JSON object with an 'ok' boolean indicating whether the token contract passed the safety check. A true value signals the token appears safe; false or error responses indicate potential risk or invalid input.
