Why raw data, not scores

A score is a liability. If a token rugs after we score it 8/10, someone blames us. Raw facts (is_honeypot, buy_tax, top_10_holder_rate, liquidity_usd) are verifiable on-chain. The buyer pays for data, keeps the judgment.

Payment

x402 v2, exact scheme:

• network: eip155:5042 (Arc mainnet)

• asset: USDC (0x3600…0000) via EIP-3009 transfer-with-authorization

• facilitator: Circle (https://api.circle.com/v1/facilitator/x402)

Send the signed payment in the X-PAYMENT header (base64url JSON). A missing or invalid payment returns 402 with paymentRequirements in WWW-Authenticate: x402 ….

Run your own

Node 20+, no database, no Docker:

cd token-security-mcp
npm i
echo 'SELLER_PRIVATE_KEY=0x…   # receives USDC' > .env
node security-server.js      # listens :3000

Put it behind a Cloudflare Tunnel (free) for a public URL. That is exactly how the live endpoint above is hosted.
