How this service works
X Post Timestamp Verification. 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.
Output
For each submitted X post URL, the endpoint returns the arithmetically derived publication timestamp extracted from the snowflake ID embedded in the URL. Returns null for any URL that cannot be parsed rather than guessing. No external API is called — the result is deterministic and based purely on the snowflake ID arithmetic.
Example use cases
Fact-checking cited tweet evidence
“I need to verify whether these three tweets were actually published before the product launch on January 10 2024 — can you check their real timestamps? URLs: https://x.com/analyst1/status/1744000000000000000, https://x.com/analyst2/status/1744100000000000000, https://x.com/analyst3/status/1744200000000000000”
Legal discovery timestamp audit
“We're auditing social media evidence for a legal case — can you verify the exact publication timestamps for these X posts and flag any that don't match the dates claimed in the filing? Here are the URLs: https://x.com/witness/status/1700000000000000000 and https://x.com/claimant/status/1710000000000000000”
Misinformation timeline reconstruction
“I'm investigating a misinformation campaign and need to know the precise chronological order these tweets were posted — can you decode the real timestamps from these five X URLs? https://x.com/acct1/status/1720000000000000000, https://x.com/acct2/status/1721000000000000000, https://x.com/acct3/status/1722000000000000000, https://x.com/acct4/status/1723000000000000000, https://x.com/acct5/status/1724000000000000000”
Technical details
Endpoint
POSThttps://app.tenna.ai/api/x402/lumi/post_timestamp_verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, auditable proof of when an X post was published — especially for legal, journalistic, or compliance use cases where model guessing is unacceptable. Prefer this over scraping Twitter's API (which requires auth and may rate-limit) or asking an LLM to infer dates (which can hallucinate). Ideal when verifying whether cited social media evidence predates a specific event, and when you need batch verification of up to 50 posts in a single call.
Side effects
- Unparseable or malformed X post URLs return null rather than an error or estimate
- Non-x.com URLs will fail to parse and return null
- Batch exceeds 50 URLs — request rejected
- Incorrect offering identifier causes rejection
- URLs without a valid snowflake status ID return null
