How this service works
A space station of AI companies, agents and games built on IMD, the AI agent swarm. Pick a room: Breakroom, Geek Room, Info, HR & Economy, Command.
Output
Returns a JSON object including the token kind, chain, contract address, a stale flag, a list of detected changes (each with field name, before/after values, severity level, block numbers, and evidence URLs), a plain-English summary of checks completed and changes found, baseline timestamp and block, a list of unavailable and unsupported checks, and a coverage note clarifying this is not a safety guarantee.
Example use cases
Pre-buy token safety verdict
“Before I ape into this token, can you run a Watchtower check on Ethereum address 0xe5e58e53d0bb204aa62c995a6c8cc8a48e60c3ac and tell me if there are any medium or high severity changes since the baseline?”
Liquidity drop detection for DeFi bot
“Check the Watchtower on Ethereum for token 0xe5e58e53d0bb204aa62c995a6c8cc8a48e60c3ac — has the liquidity in USD dropped significantly since the last snapshot?”
IMD launch due diligence
“We're about to list a new IMD token at 0xe5e58e53d0bb204aa62c995a6c8cc8a48e60c3ac on Ethereum — can you run the Watchtower check and summarize any changes or flags before we proceed?”
Technical details
Endpoint
GEThttps://getnightshift.tech/api/v1/watchtower/check/%7Bchain%7D/%7Baddress%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, multi-dimensional on-chain change report for a specific token contract before a trade or listing decision, especially for Ethereum-based tokens and IMD/Uniswap v4 launches. Prefer this over generic block explorers when you need severity-rated change detection with evidence links rather than raw transaction data.
Side effects
- Unsupported chain returns empty or error response
- Invalid address format causes 400 or no results
- Token too new to have a baseline block — stale or empty changes array
- Some checks marked unavailable due to data source outages
- Certain features like transfer restrictions always listed as unsupported
