Permit data
Last verified .
/data/permits.json is the only permit record file we publish. Each record is one we maintain: a title, park, status, last-verified date, stale-after date, the short window sentence, how to apply, official source URLs, the next window we print, conditions, an alerts link, and a weather link when we have one. A record can also include typical_season when the dates are a usual pattern and not a confirmed season. That object keeps typical: true and guaranteed: false. Unpublished records are included so the calendar can name them. They have "published": false and "url": null.
The file does not include raw Recreation.gov payloads, facility inventory dumps, or third-party copies. It leaves out internal working notes, weather-grid coordinates, and verification paths. It does not include affiliate URLs.
The shape is the permit schema. Responses are application/json with X-Content-Type-Options: nosniff. The HTML page for a published record remains the citation. Use the page URL, the last-verified date, and the official source next to the fact.
