How this service works
Fresh crypto narrative research with market context and verifiable source URLs. Free BTC sample; custom radar $0.02/call via x402 USDC.
Output
Returns a JSON object with: ok (boolean), symbol, product name, a plain-English verdict string, liquidity description, risk_level (e.g. low-medium), numeric risk_score, arrays of red_flags and green_flags, holder_concentration summary, and a disclaimer stating it is automated research and not financial advice.
Example use cases
Pre-trade token safety check
“Before I buy some PEPE, can you run a quick due diligence on it? I want the risk score, liquidity, and any red flags — in English please.”
DeFi contract risk assessment
“I found this token with contract address 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 — can you check its on-chain security and holder concentration for me?”
Crypto narrative and liquidity research
“Can you do a token DD on SOL focusing on liquidity? Give me the verdict, green flags, and overall risk level in English.”
Technical details
Endpoint
GEThttps://x402donghang.duckdns.org/x402/v1/token-ddWhen to prefer
Choose this endpoint when you need a fast, structured, AI-generated risk snapshot for a specific crypto token, especially when you want a machine-readable verdict (risk score, flags, holder concentration) rather than a lengthy narrative. Particularly useful for agents automating pre-trade screening or building crypto research pipelines. Supports both English and Chinese output. Prefer alternatives if you need real-time price data, order book depth, or official audit reports.
Side effects
- Unknown or very new token symbol with no on-chain data — may return empty flags or inconclusive verdict
- Invalid or malformed contract address — may fail validation or return generic analysis
- Token with extremely low liquidity may produce unreliable liquidity assessments
- Payment not received via x402 — request blocked with 402 Payment Required
- Network timeout or model inference failure — returns error response
