The dataset. Free. Cite it.

• /data/claims.json: 346 claims. Each has a stable claim_id, the verdict, the first and current deadline, and a timeline of every statement (first, restated, goalpost_moved) with its quote and source URL.
• /data/predictions.json: 463 statements, one per time he said it. Ids never change; group by claim_id.
• /data/changelog.json: what changed and when (new claims, verdicts, moved deadlines). Poll it to stay current.
• /data/schema.json: field definitions and status values. Every file carries retrieved (build date) and schema_version.
• Each page URL is https://twoweeks.lol/predictions/<slug>/; an old statement URL redirects to its claim page at #<slug>.

Method. A claim counts only if Musk said it himself (post, video, interview, blog or earnings call) and it names or implies a date. "Said" is the date of that source; "deadline" is the date he gave, before any goalpost move. Verdicts follow the definitions on the methodology page; every count on this page is computed from the same file you can download.
