Skill that runs a pre-trade safety check on Base ERC-20 tokens (honeypot/sellability, measured transfer tax, owner/mint/pause flags, liquidity, SAFE/CAUTION/AVOID verdict) by curling the Grey Ridge x402 API's free preview endpoint. Skill-only: no tools, hooks or env vars.

## Good to know before installing

The skill has the agent run `curl` against Grey Ridge Signals Group LLC's API (x402-data-api.sigrunner.workers.dev, the same service as api.greyridgesignals.ai) with the token address and, for the swap gate, trade side and USD size; each response carries a paid URL that the skill tells the agent it can call with an x402 client (suggesting `npm i x402-fetch viem`), paying $0.01 USDC per call on Base from whatever wallet that client is given, and it mentions an unpinned `pip install git+https://github.com/rezearcher/greyridge-x402-tools` helper that the user installs themselves. Its verdict is a heuristic, not financial advice.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install greyridge-token-safety
```

2. Said no? Turn it on later:

```bash
hermes plugins enable greyridge-token-safety
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
