# Token Safety & Contract Risk API
[](https://token-safety.api.klymax402.com/mcp)
[](https://x402.org)
[](LICENSE)
Token contract safety scanner -- honeypot, tax, proxy, blacklist, ownership. Rug-pull protection for agents. Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the [klymax402](https://klymax402.com) marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
## Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
```json
{
"mcpServers": {
"token-safety": {
"url": "https://token-safety.api.klymax402.com/mcp"
}
}
}
```
## Quickstart -- HTTP (x402)
```bash
curl "https://token-safety.api.klymax402.com/api/check?address=0x0000000000000000000000000000000000dEaD"
# -> 402 Payment Required, with an x402 payment challenge in the response body
```
Any x402-aware client ([`@x402/fetch`](https://www.npmjs.com/package/@x402/fetch), [`x402-agent-tools`](https://www.npmjs.com/package/x402-agent-tools), ATXP) handles the 402 -> sign -> retry cycle automatically.
## Tools
| Tool | Method | Path | Price | Description |
|---|---|---|---|---|
| `token_check_safety` | GET | `/api/check` | $0.008 | Check token contract safety and risk score |
### `token_check_safety`
Use this when you need to check if a token is safe before buying or interacting with it. Returns a comprehensive safety report in JSON.
**Parameters**
| Name | Type | Required | Description |
|---|---|---|---|
| `address` | string | yes | Token contract address (e.g. 0x...) |
| `chain` | string | no | Chain to check on: 'ethereum' or 'base' (default: ethereum) |
**Returns**
- `isHoneypot` -- whether the token traps buyers (cannot sell)
- `ownershipRenounced` -- whether the contract owner has renounced control
- `isProxy` -- whether the contract is upgradeable (proxy risk)
- `buyTax` -- percentage tax on buy transactions
- `sellTax` -- percentage tax on sell transactions
- `maxTxPercent` -- maximum transaction size as percent of supply
- `liquidityLocked` -- whether liquidity is locked
- `hasBlacklist` -- whether contract has a blacklist function
- `holderCount` -- total number of token holders
- `riskScore` -- overall risk score (0=safe, 100=dangerous)
Example response:
```json
{"isHoneypot":false,"ownershipRenounced":true,"isProxy":false,"buyTax":0,"sellTax":0,"maxTxPercent":100,"liquidityLocked":true,"hasBlacklist":false,"holderCount":15420,"riskScore":12}
```
**When to use**: buying any new or unknown token. Essential for rug-pull protection and due diligence.
**Not for**: token prices (use `dex_get_swap_quote`), wallet balance (use `wallet_get_portfolio`), holder distribution (use `token_get_holder_analysis`).
