🔍 What It Does

SicariusGuard performs 12 layers of safety analysis on any Solana SPL token or NFT:

On-Chain Safety (Layers 1-5)

Layer	Source	Detection
🔓 Mint Authority	Raw SPL mint bytes	Can deployer print infinite tokens?
🧊 Freeze Authority	SPL layout offset 46	Can deployer freeze any wallet?
⚠️ Token-2022 Extensions	Extension type scan	PermanentDelegate, TransferHook, ConfidentialTransfers
🍯 Honeypot Detection	Jupiter sell simulation	Can you actually sell this token?
📊 Holder Concentration	`getTokenLargestAccounts`	Top 5 wallets controlling >50% supply?

LP & Token Maturity (Layers 6-8)

Layer	Source	Detection
🔒 LP Lock/Burn	Raydium V4 byte decode + GeckoTerminal	Is liquidity locked, burned, or unlocked?
⏰ Token Age	Helius enhanced RPC	Newborn (<24h)? Young (<7d)? Mature?
⚖️ Unified Scoring	5-axis weighted engine	Combined risk across all layers

Intelligence & Reputation (Layers 9-12)

Layer	Source	Detection
📈 Market Intel	Birdeye API	Liquidity, volume, wash trading, manipulation
🔎 Wallet Reputation	Helius Identity + Funded-By	Is the deployer a known scammer?
🕵️ Deployer Recon	DAS + Enhanced TX	Serial rugger? Burner wallet? Dead token history?
🖼️ NFT Intelligence	Helius DAS + Magic Eden	Counterfeit collection? Unverified creators? Pricing anomaly?

5-Axis Weighted Risk Scoring

hljs language-scss

finalScore = (onChain × 0.45) + (lpLock × 0.15) + (age × 0.05) + (market × 0.22) + (reputation × 0.13)

0       → SAFE
1-15    → CAUTION
16-50   → HIGH_RISK
51-100  → CRITICAL

Weight	Source	What It Catches
45%	On-chain safety	Mint/freeze authority, honeypots, extensions, supply
15%	LP lock analysis	Unlocked liquidity, unburned LP tokens, lock duration
5%	Token age	Newborn tokens (<24h), recently deployed
22%	Birdeye market data	Low liquidity, wash trading, price manipulation

💰 x402 Payment Protocol

SicariusGuard implements the x402 HTTP Payment Required protocol for machine-native micropayments. AI agents can pay per API call with SOL — no registration, no API keys, no accounts.

How It Works

hljs language-markdown

1. Agent hits /v1/scan → gets 402 + payment instructions
2. Agent sends SOL to treasury wallet
3. Agent retries with X-PAYMENT: <tx_signature>
4. Server verifies on-chain → returns safety data

Pricing

Endpoint	Price (SOL)	Description
`/v1/check`	0.001	On-chain safety check
`/v1/scan`	0.002	Full 12-layer scan
`/v1/honeypot`	0.0005	Honeypot simulation
`/v1/holders`	0.0005	Holder analysis
`/v1/nft-check`	0.001	NFT safety check

Example (Paid Request)

hljs language-bash

# Step 1: Get pricing + treasury address
curl https://sicarius-guard-640545264957.us-east4.run.app/v1/pricing

# Step 2: Send SOL to treasury address (returned in pricing response)
solana transfer <TREASURY_ADDRESS> 0.002

# Step 3: Use tx signature as payment proof
curl -X POST https://sicarius-guard-640545264957.us-east4.run.app/v1/scan \
  -H "Content-Type: application/json" \
  -H "X-PAYMENT: <your_tx_signature>" \
  -d '{"mint": "DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263"}'

Security

On-chain verification — Every payment is verified against Solana mainnet
Replay protection — Each tx signature can only be used once
Amount validation — Exact SOL amount must match endpoint pricing
Freshness check — Transactions older than 10 minutes are rejected
Verified live on mainnet — Tested with real SOL transfers

Access Tiers

Tier	Auth Method	Rate Limit
Free	None	100 calls/day per IP
x402 Pay-Per-Call	`X-PAYMENT` header (SOL tx sig)	Unlimited

🔧 Configuration

Variable	Description	Default
`HELIUS_RPC_URL`	Solana RPC endpoint (Helius recommended)	`https://api.mainnet-beta.solana.com`
`PORT`	API server port	`3400`
`HOST`	Bind address	`0.0.0.0`
`BIRDEYE_API_KEY`	Birdeye API key (optional, enriches scans)	—
`TREASURY_WALLET`	SOL payment recipient (x402)	—
`CACHE_TTL_SECONDS`	Cache duration	`300`
`FREE_TIER_CALLS_PER_DAY`	Free tier rate limit	`100`
`UPSTASH_REDIS_REST_URL`	Upstash Redis URL for persistent rate limiting	—
`UPSTASH_REDIS_REST_TOKEN`	Upstash Redis auth token	—

📊 Performance

Tested with 50-token bulk scan on Solana mainnet:

Metric	Value
Success rate	50/50 (100%)
Avg response time	5.4s
x402 payment verification	Verified live on mainnet

📦 Tech Stack

Runtime: Node.js 22+ (ESM)
Language: TypeScript 5.9
Blockchain: @solana/web3.js (direct RPC, no wrapper SDKs)
API: Express 5
MCP: @modelcontextprotocol/sdk
Market Data: Birdeye API v3
NFT Data: Magic Eden v2 API (free tier)
Wallet Intel: Helius DAS / Identity / Funded-By APIs
Pool Data: GeckoTerminal API + Raydium V4 byte decode

🛡️ Why SicariusGuard?

Most token safety tools rely on third-party APIs that can be gamed. SicariusGuard reads raw mint account bytes directly from the blockchain — the same data the Solana runtime uses to execute transactions. No middleman, no stale data, no API that can be fooled.

💰 x402 Payment Protocol

SicariusGuard implements the x402 HTTP Payment Required protocol for machine-native micropayments. AI agents can pay per API call with SOL — no registration, no API keys, no accounts.

How It Works

hljs language-markdown

1. Agent hits /v1/scan → gets 402 + payment instructions
2. Agent sends SOL to treasury wallet
3. Agent retries with X-PAYMENT: <tx_signature>
4. Server verifies on-chain → returns safety data

Pricing

Endpoint	Price (SOL)	Description
`/v1/check`	0.001	On-chain safety check
`/v1/scan`	0.002	Full 12-layer scan
`/v1/honeypot`	0.0005	Honeypot simulation
`/v1/holders`	0.0005	Holder analysis
`/v1/nft-check`	0.001	NFT safety check

Example (Paid Request)

hljs language-bash

# Step 1: Get pricing + treasury address
curl https://sicarius-guard-640545264957.us-east4.run.app/v1/pricing

# Step 2: Send SOL to treasury address (returned in pricing response)
solana transfer <TREASURY_ADDRESS> 0.002

# Step 3: Use tx signature as payment proof
curl -X POST https://sicarius-guard-640545264957.us-east4.run.app/v1/scan \
  -H "Content-Type: application/json" \
  -H "X-PAYMENT: <your_tx_signature>" \
  -d '{"mint": "DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263"}'

Security

On-chain verification — Every payment is verified against Solana mainnet
Replay protection — Each tx signature can only be used once
Amount validation — Exact SOL amount must match endpoint pricing
Freshness check — Transactions older than 10 minutes are rejected
Verified live on mainnet — Tested with real SOL transfers

Access Tiers

Tier	Auth Method	Rate Limit
Free	None	100 calls/day per IP
x402 Pay-Per-Call	`X-PAYMENT` header (SOL tx sig)	Unlimited

🔧 Configuration

Variable	Description	Default
`HELIUS_RPC_URL`	Solana RPC endpoint (Helius recommended)	`https://api.mainnet-beta.solana.com`
`PORT`	API server port	`3400`
`HOST`	Bind address	`0.0.0.0`
`BIRDEYE_API_KEY`	Birdeye API key (optional, enriches scans)	—
`TREASURY_WALLET`	SOL payment recipient (x402)	—
`CACHE_TTL_SECONDS`	Cache duration	`300`
`FREE_TIER_CALLS_PER_DAY`	Free tier rate limit	`100`
`UPSTASH_REDIS_REST_URL`	Upstash Redis URL for persistent rate limiting	—
`UPSTASH_REDIS_REST_TOKEN`	Upstash Redis auth token	—

📊 Performance

Tested with 50-token bulk scan on Solana mainnet:

Metric	Value
Success rate	50/50 (100%)
Avg response time	5.4s
x402 payment verification	Verified live on mainnet
