# OnchainPulse EVM Token Safety Scanner

> OnchainPulse EVM Token Safety Scanner is a paid API for AI agents from onchainpulse.theaslangroupllc.com, paid per call via x402, $0.015/call, status unknown (last checked 2026-09-14).

Runs a comprehensive pre-trade safety check on any EVM token — honeypot detection, tax analysis, contract risk flags, and liquidity health — returning a single CLEAR/CAUTION/AVOID verdict.

## 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 onchainpulse-evm-token-safety-scanner-428ece8c
```

Example prompt: Before I buy this token, can you run a full safety scan on contract 0x1234...abcd on Base — check if it's a honeypot, what the buy/sell taxes are, whether the LP is locked, and give me the overall CLEAR, CAUTION, or AVOID verdict?

## When to prefer this

Use this endpoint when an AI trading agent needs a rapid, all-in-one pre-trade risk verdict on an EVM token before executing a buy — especially on Base, Ethereum, BSC, Arbitrum, Polygon, Optimism, or Avalanche. Prefer over manual contract audits when speed and breadth of checks (honeypot + tax + contract flags + liquidity) are needed in a single call.

## Known failure modes

- Unrecognized or unsupported chain ID returns an error
- Invalid or malformed contract address returns a 400-level error
- Token not yet indexed or no liquidity found returns partial/empty result
- Network RPC issues may cause timeout or incomplete scan
- Very new token with no trade history may have indeterminate honeypot simulation result

## How this service works

Honeypot, rug & token-safety scanner for Robinhood Chain, Base & EVM tokens — instant pre-trade check: sell-simulation honeypot, buy/sell tax, mint, upgradeable proxy, pausable transfers, blacklist, owner privileges, LP lock/burn, holder concentration, fused with live liquidity & flow into one CLEAR / CAUTION / AVOID verdict. Robinhood Chain (launchpad tokens incl. Pons), Base, Ethereum, BSC + 4 more. Answers: is this token safe to buy?

## Output

A structured safety report containing a top-level CLEAR/CAUTION/AVOID verdict plus individual flags: honeypot sell-simulation result, buy tax %, sell tax %, mint authority, upgradeable proxy, pausable transfers, blacklist capability, owner privilege level, LP lock/burn status, holder concentration metrics, and live liquidity data.
