Each operation describes its service.
Output
Returns a JSON object with an overall ok status, a count of tokens evaluated, and per-token results including: chain, risk score (0-100), token name and symbol, contract address, a verdict string (e.g. lower_risk, moderate_risk, high_risk), a degraded flag, a list of red flags, source status for RPC/GoPlus/DexScreener, and total liquidity in USD. Also includes a summary with aggregate verdict counts and a riskiest-first ordering.
Example use cases
Pre-purchase token safety check
“Before I swap into this new token at 0x1234abcd... on Base, can you run a due diligence check and tell me if there are any red flags or if the liquidity looks thin?”
Rug pull detection for airdrop token
“I just got airdropped a token on Ethereum at address 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 — can you check whether it's a scam or rug pull and give me a risk verdict?”
Portfolio risk audit across chains
“I hold AERO on Base and USDC on Ethereum — can you run a risk assessment on both token addresses and rank them from riskiest to safest with scores?”
Technical details
Endpoint
GEThttps://api.firstmention.uk/s/token-dd/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, multi-signal risk score for a specific token contract address — especially before trading, investing, or interacting with an unknown token. It aggregates RPC, GoPlus, and DexScreener data into a single verdict, making it superior to manually querying each source. Ideal for DeFi agents, portfolio managers, or any workflow that needs automated token safety checks on Base or Ethereum.
Side effects
- Unknown or unsupported chain identifier returns an error
- Invalid or non-contract address returns no results or error
- Degraded source status (e.g. GoPlus unavailable) may reduce scoring accuracy
- Rate limiting or payment failure (402) if USDC payment not properly attached
- Token with no on-chain liquidity may return incomplete liquidity data
