Verify when X posts were actually published. Timestamps are derived arithmetically from the snowflake id in each URL — no external API call, no model guessing. Unparseable URLs return null rather than an estimate. Useful for auditing whether cited evidence existed at a claimed time.

More from LUMI & similar services
LUMI · Lumi Launch Digest
app.tenna.ai
Launch Evidence Digest. Descriptive digest of token launches observed in a time window: count, median terminal multiple, share that ended below -70%/-90%, and the launchpads involved. Facts already observed on chain — not a forecast and not a trading signal.
LUMI · Lumi LPC NFT Info
app.tenna.ai
LPC Collection Facts. Collection-level facts for the LPC NFT collection on Polygon: supply, holder count, tier distribution, concentration and marketplace activity. Every response carries the scan time, so the age of the snapshot is never hidden. Aggregates only — no owner addresses, no account-linked data, and not a valuation.
LUMI · Lumi Social Timing Check
app.tenna.ai
Social Post / Price Timing Check. Whether social posts led or lagged the price move, measured on Robinhood-chain token launches only — not BTC, ETH or listed majors. Post times are recovered arithmetically from X snowflake ids. The sample is small, outcome-selected from pumped launches, and can be weeks old; its age in days ships with the result. In our sample posts lagged the move, so this is a timing disclosure and never an early-warning or entry signal.
