# DeFi Safety Oracle – Token Safety Checker

> DeFi Safety Oracle – Token Safety Checker is a paid API for AI agents from oracle.cyberwarex.com, paid per call via x402, $0.06/call, status unknown (last checked 2026-10-13).

Analyzes an ERC-20 token on Base or BSC for honeypot/rug-pull risk using on-chain DEX simulation and third-party cross-checks, returning an A–F safety grade.

## Facts

- Endpoint: GET https://oracle.cyberwarex.com/token?utm_source=zero.xyz
- Price: $0.06/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/defi-safety-oracle-token-safety-checker-f3645cf4
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_GrXsPWcUCwxRaBLUE3Rf_

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 defi-safety-oracle-token-safety-checker-f3645cf4
```

Example prompt: Can you check if the token at 0xAbC123... on Base is safe to trade — run a full honeypot and rug simulation and tell me the safety grade?

## When to prefer this

Choose this endpoint when you need a deterministic, simulation-based safety verdict on a specific ERC-20 token on Base or BSC — especially when you need more than a static analysis and want actual eth_call state-override simulation against live DEX pools (Aerodrome, Uniswap V2/V3), combined with GoPlus and honeypot.is cross-validation. Prefer this over generic block explorers or static contract scanners when real sell-ability simulation matters.

## Known failure modes

- Invalid or non-existent contract address returns an error or F grade with no simulation data
- Unsupported chain (not base or bsc) returns a validation error
- Token with no liquidity pool on supported DEXes may fail simulation with an error
- Rate limiting or payment failure (x402) blocks the call
- Newly deployed contracts may have insufficient on-chain state for simulation

## How this service works

Full safety report for an ERC-20 token. Runs a live buy-then-sell honeypot and tax simulation against real DEX liquidity (Aerodrome, Uniswap V2/V3/V4), scans contract powers (upgradeable proxy, mint, pause, blacklist, fee-setting), resolves ownership and effective controllers, and cross-checks GoPlus and honeypot.is. Returns an A-F grade, tradeable flag, 0-100 risk score and evidence-carrying flags an agent can cite.

## Output

Returns a JSON object with a letter grade (A–F) summarizing overall safety, a boolean indicating whether the token is tradeable (i.e., you can buy AND sell), and a human-readable summary of detected risks such as honeypot mechanics, blacklist functions, mint authority, or high buy/sell tax.
