# OnchainPulse Token Safety Check

> OnchainPulse Token Safety Check 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).

Checks whether a token is safe to buy by running rug-pull and honeypot analysis across 10 chains, returning a single CLEAR/CAUTION/AVOID verdict with supporting risk signals.

## 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-token-safety-check-4a31fe8b
```

Example prompt: Before I swap into it, can you check if the token at address 0x6B175474E89094C44Da98b954EedeAC495271d0F is safe — I need to know if it's a honeypot or rug pull risk on Ethereum.

## When to prefer this

Use this endpoint when you need a fast, single-call, cross-chain token safety verdict before executing a swap or recommending a token to a user. It is ideal for trading agents, wallet guardrails, and DeFi automation pipelines that need a deterministic CLEAR/CAUTION/AVOID signal without building custom rug-detection logic. Prefer this over manual on-chain inspection when you need sell-simulation honeypot detection, authority flag checking, and LP analysis fused into one response across 10 chains including Solana, EVM chains, and Algorand.

## Known failure modes

- Unknown or unresolvable token address — returns error if address doesn't match any supported chain format
- Unsupported chain — if chain override is provided but not in the supported list, returns validation error
- Token too new or no liquidity data available — may return CAUTION or incomplete signals
- Network timeout fetching live on-chain data — may return partial results or error
- Invalid address format — malformed address string returns a 400-level error

## How this service works

Token safety check — answers "is this token safe to buy?" for any token: one deterministic CLEAR / CAUTION / AVOID rug & honeypot verdict across 10 chains (Solana, Base, Ethereum, BSC, Arbitrum, Polygon, Optimism, Avalanche, Robinhood Chain, Algorand). Auto-detects the chain from the address shape. Sell-simulation honeypot, mint/freeze/clawback authority, LP lock/burn, holder concentration, live liquidity — fused into one verdict. Pre-swap guardrail for trading agents and agent wallets.

## Output

Returns a single deterministic verdict of CLEAR, CAUTION, or AVOID along with supporting signals including honeypot sell-simulation result, mint/freeze/clawback authority presence, LP lock/burn status, holder concentration metrics, and live liquidity figures. Chain is auto-detected from the address format.
