Global Entry wait-times API

Free, read-only JSON — no authentication, no key. Use it in apps, research, or AI assistants. Attribution appreciated: link to haya.merrowa.com.

Endpoints

• GET /api/locations.json — every enrollment center with current interview wait (wait_days), slots in the next 30 days, group-booking availability (group_wait_days — days until N slots fall within one 60-minute window), programs offered, and contact details. Refreshed weekly.
• GET /scarcity.json — compact wait-time data keyed by center id (the same feed our location pages refresh from).
• GET /llms.txt — plain-text service description for LLMs.

Example

curl -s https://haya.merrowa.com/api/locations.json | jq '.locations[0]'

Notes

• Freshness: wait numbers are probed weekly from the public CBP scheduler; wait_data_as_of carries the probe timestamp. wait_days: null means no open interview is listed; a center missing from the weekly probe has null in all wait fields.
• Serving: static files behind a CDN — cheap to poll, but there's no point polling more than daily. No CORS headers; fetch server-side.
• License: CC BY 4.0. Source data is the public CBP Trusted Traveler scheduler; Haya is not affiliated with CBP or DHS.
