How this service works
tokenSafety — insight tier ($0.04 USDC)
Output
Returns a structured JSON object containing: overall safety score (0-100), verdict string (e.g. SAFE), verdict explanation, list of risk flags, key risk factors, key positive factors, token metadata (name, symbol, price, market cap), chain, contract address, whether it's listed on CoinGecko, data freshness timestamp, model used, data sources, and pointers to higher-tier upgrade paths.
Example use cases
Example prompt
“Can you check whether the Ethereum token at contract address 0x6B175474E89094C44Da98b954EedeAC495271d0F is safe — give me the safety score, verdict, and any major risk flags?”
Technical details
Endpoint
GEThttps://express-legacy-production.up.railway.app/crypto/token-safety/insightWhen to prefer
Use this insight-tier endpoint (vs. the $0.001 quick tier) when you need richer safety context — including verdict explanations, key positive factors, and structured risk flags — but don't yet need the full forensic/audit-level analysis of the pro ($1.00) or analysis tiers. Ideal for pre-trade due diligence, portfolio screening, or alerting workflows where moderate depth and low cost ($0.04) are both important.
Side effects
- Invalid or unsupported contract address format — returns error or empty result
- Unsupported chain value — enum validation failure
- Token not found on CoinGecko or DefiLlama — may return limited data or low confidence score
- Payment not processed (x402) — 402 Payment Required response
- Rate limiting or upstream data source unavailability — delayed or partial response
