If you're building a crypto app, a trading bot, a DeFi dashboard, or an AI agent that touches wallets or tokens, you need security signals baked in — not bolted on after something goes wrong.

RelayShield Security Intelligence is a single REST API that gives you:

• Wallet risk scoring: Multi-chain (EVM, Solana, TON)
• Token honeypot + rug pull detection: Before your users ape in
• NFT contract risk scanning: Ownership, minting, verification flags
• SIM swap detection: Live carrier-layer data via Twilio Lookup v2
• Email breach checking: 13B+ compromised records

No SDKs. Plain JSON in, plain JSON out. Available on RapidAPI (subscription) or x402 USDC micropayments on Base (pay per call, no subscription needed).

Quickstart — Wallet Risk in Python

import requests

url = "https://relayshield-security-intelligence.p.rapidapi.com/v1/wallet-risk"

payload = { "address": "0xYourWalletAddress" }
headers = {
    "x-rapidapi-key": "YOUR_RAPIDAPI_KEY",
    "x-rapidapi-host": "relayshield-security-intelligence.p.rapidapi.com",
    "Content-Type": "application/json"
}

response = requests.post(url, json=payload, headers=headers)
print(response.json())

Works with EVM addresses, Solana public keys, and TON wallet addresses — the API auto-detects chain type.

Quickstart — Token Security (Honeypot Check)

payload = {
    "chain_id": "1",  # Ethereum mainnet — use 8453 for Base
    "contract_address": "0xTokenContractAddress"
}

response = requests.post(
    "https://relayshield-security-intelligence.p.rapidapi.com/v1/token-security",
    json=payload,
    headers=headers
)
print(response.json())

Returns honeypot status, buy/sell tax flags, ownership renounced, hidden owner, and more.

Pay Per Call with x402 (No Subscription Needed)

If you're building an agent or a low-volume integration and don't want a monthly subscription, the PAYG endpoints accept x402 USDC micropayments on Base:

x402 flow:

1. Call the endpoint with no payment header → receive 402 + PAYMENT-REQUIRED
2. Pay USDC on Base to the address in the response
3. Retry with X-PAYMENT header containing payment proof
4. API verifies via Coinbase x402 facilitator → returns result

Use Cases

• DeFi dashboard: Screen every inbound token for honeypots automatically
• Trading bot: Run wallet-risk on counterparties before executing swaps
• AI agent: Give your Claude/GPT agent live security intelligence via MCP or direct API
• Wallet app: Alert users when their SIM is swapped before their 2FA is compromised
• Portfolio tracker: Flag high-risk wallets and scam tokens in real time

MCP Server (Claude / AI Agents)

If you're building with Claude or want to use these signals inside Claude Desktop:

pip install relayshield-mcp

Exposes all endpoints as native MCP tools — no API calls to write.
