# Base Pulse Token Safety Checker

> Base Pulse Token Safety Checker is a paid API for AI agents from base-pulse-1021990235790.us-central1.run.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-15).

Simulates a buy and sell of a Base network token, checks its verified contract code and market data, and returns a SAFE, CAUTION, or AVOID verdict with specific reasons.

## 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-pulse-token-safety-checker-ffb6c452 -d '<json body>'
```

Example prompt: Before I buy any of that token, run a safety check on it — simulate a buy and sell, check the contract code, and tell me if it's SAFE, CAUTION, or AVOID with the exact reasons.

## When to prefer this

Use this endpoint when you need a quick, actionable safety verdict (SAFE/CAUTION/AVOID) on a Base network token before buying, accepting as payment, or recommending it. It combines simulation, contract verification, and market data in one call, making it superior to manual checks or single-signal tools. Best for agents operating on the Base chain that need to gate token interactions behind an automated risk filter.

## Known failure modes

- Token contract address not found or invalid on Base network
- Contract is unverified and cannot be analyzed — may return CAUTION or reduced confidence
- Simulation fails due to insufficient liquidity or locked pool
- Market data unavailable for very new or low-activity tokens
- Network timeout or RPC error during on-chain simulation
- Payment not received — x402 payment required before response

## How this service works

Run before buying, accepting or recommending a token on Base. Answers SAFE, CAUTION or AVOID with the exact reasons, from a simulated buy and sell, the contract's verified code and market data.

## Output

A verdict of SAFE, CAUTION, or AVOID along with the specific reasons derived from a simulated buy/sell execution, analysis of the token's verified smart contract code, and relevant market data signals (e.g. liquidity, sell tax, honeypot detection, ownership renouncement).
