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: Endpoint Price /v1/payg/wallet-risk $0.15 USDC /v1/payg/token-security $0.10 USDC /v1/payg/nft-security $0.10 USDC /v1/payg/wallet-screen-batch $0.50 USDC (up to 10 addresses) /v1/payg/breach $0.10 USDC /v1/payg/sim-swap $0.25 USDC x402 flow: Call the endpoint with no payment header → receive 402 + PAYMENT-REQUIRED Pay USDC on Base to the address in the response Retry with X-PAYMENT header containing payment proof 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.
