How this service works
Keyless off-chain and on-chain data for AI agents. No API key, no signup - payment is the only gate. Pay-per-call in USDC on Base via x402.
Output
A JSON object containing: a risk_score (0–1 float), a risk_band label (e.g. 'low'/'medium'/'high'), the network (eip155:8453 for Base), the token_address, and a factors object with liquidity_usd, pair_age_hours, top1_holder_pct, top5_holder_pct, contract_verified (bool), high_risk_functions (count + list), and ownership_renounced (bool).
Example use cases
Evaluate token safety before swapping
“I'm about to swap into a Base token but want to make sure it's not a rug pull. Can you check the risk score, liquidity age, top holder concentration, and whether the contract is verified for address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913?”
Screen DeFi portfolio for red flags
“I hold several tokens on Base. Can you pull the risk assessments for these addresses and flag any that have high holder concentration, unverified contracts, or dangerous functions? [0x4200000000000000000000000000000000000006, 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, 0xd9aAEc860b8A672B100b131B396175bB5dF1b5b1]”
Audit contract security for partnerships
“We're considering a partnership with a Base token project. Can you give me a comprehensive breakdown of the risk factors — including whether ownership is renounced, if there are any high-risk functions in the contract, holder concentration levels, and overall risk band for their token at 0xd9aAEc860b8A672B100b131B396175bB5dF1b5b1?”
Technical details
Endpoint
GEThttps://lion-x402.lionmaster-operations.workers.dev/api/x402/token-risk-indicators-jsonWhen to prefer
Use this endpoint when you need a fast, pre-computed multi-factor risk assessment for a specific Base chain token without setting up API keys. Ideal for agents performing DeFi due diligence, wallet risk checks, or token screening pipelines that pay per call via x402 USDC micropayments. Prefer over manual on-chain queries when you want a single normalized risk_score plus human-readable risk_band alongside holder and contract factors in one call.
Side effects
- Payment not received or invalid x402 payment header — returns 402 Payment Required
- Invalid or non-existent token address — may return empty factors or error object
- Token not deployed on Base — endpoint only covers eip155:8453, wrong chain returns error or null data
- Rate or node issues on the underlying RPC — may return 503 or partial data
