PoolProof Chain Liveness Check
x402
PoolProof Chain Liveness Check is a paid API for AI agents from poolproof.ru, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Analyzes whether a blockchain is still alive by examining TVL trends across 1-year, 6-month, 90-day, and 30-day windows, flagging collapsed or declining ecosystems.

How this service works
Is this chain alive: TVL trend over 1y/6m/90d/30d
Output
Returns a JSON object with an 'ok' boolean, a 'verdict' string summarizing chain liveness, a 'disclaimer', and a 'flags' array of objects containing 'code' and 'msg' fields. Flag codes include COLLAPSED, STILL_FALLING, and TINY. An empty flags array means the chain passed all checks.
Example use cases
Pre-deployment chain viability check
“Before we deploy our new DeFi protocol on Celo, can you check if the chain is still alive — look at the TVL trend over the past year and tell me if it's flagged as collapsed, falling, or too small to matter?”
Filtering dead chains from a yield aggregator
“I'm building a list of chains to include in our yield aggregator — can you run a liveness check on Moonbeam and tell me if its TVL trend shows it's abandoned or just quiet?”
Investor due diligence on alt-chain ecosystem
“I'm considering putting capital into a project on Metis — can you check whether the Metis chain is actually still alive, what direction the TVL is trending over the last 6 months, and whether it's flagged as COLLAPSED or STILL_FALLING?”
Technical details
Endpoint
POSThttps://poolproof.ru/v1/chainWhen to prefer
Use this endpoint when you need a structured, multi-window TVL-based verdict on whether a blockchain is still viable — not just a current TVL snapshot. It is especially valuable when you need categorical flags (COLLAPSED, STILL_FALLING, TINY) to programmatically filter out dead or dying chains before routing capital, deploying contracts, or sourcing yield opportunities. Prefer this over raw TVL APIs when you need pre-computed trend analysis and risk flags rather than raw numbers.
Side effects
- Unknown or unsupported chain identifier returns an error or empty verdict
- Chain with no indexed TVL history may return insufficient data
- Misspelled chain name may fail to resolve to a known chain
- Newly launched chains may lack enough historical windows to render a verdict
