Use the Lostalgia API to read the lost and found items on the map from your own app or website. It gives the same public information anyone sees on the map, without names or contact details.

OpenAPI description 1.0.0 (YAML) ↗
All versions and support dates ↗
Free plan: all the read endpoints, 100 requests a day per key (UTC). Leave at least 1 second between requests. Every response tells you how many are left.
Paid plans with higher limits are coming later.
Version 1.0.0 is supported until 31 December 2026.
Keep your key secret. Use the data only to help return lost items: never to contact, identify or track people. Show “Data from Lostalgia” with a link to each item, keep copies for 24 hours at most, and stop showing an item within 24 hours after it leaves the map. See the Terms of Use.
