• products.codex.events / products.claude.events — newest first.
• date is the announcement date (UTC). ts is the exact post time when known; records imported from public archives have null.
• scope: all, paid, Max, Pro+Max, Plus+Pro+Business, affected — parsed from the announcement text.
• url links to the original post. Records without a link came from an archive; the posting account is in source.

Example

const r = await fetch("https://agentresets.com/api/resets.json").then(r => r.json());
const last = r.products.codex.events[0];
console.log(`Last Codex reset: ${last.date} (${last.scope})`);
