List check-ins

Returns the global check-in feed, newest first, optionally narrowed by the filters below. Records are anonymized: each carries the fully expanded location (with its restaurant), but no user field, so the feed cannot be attributed to members. For a member’s own history use GET /users/me/check_ins.

Chef’s warning - The user filter is gone. Passing user= (or user_id=) is silently ignored and returns the full unfiltered list — and since records carry no user field, there is nothing to match client-side either. Filter by restaurant or location.

Tasting note - All filters are optional. A bare GET /check_ins returns the full paginated set (~15.7k records in staging), so page deliberately when you omit filters.

Auth: API key in X-API-Key — no user token needed. Two requirements beyond the header:

The key must carry the read:checkins scope. Key scopes are set in the body of the key-mint request; the app’s allowed_scopes are not inherited, so a key minted with an empty body gets 403 here even if its app lists read:checkins.
Send a non-empty User-Agent. The edge rejects a missing or empty User-Agent with a 403 HTML body, but any non-empty value — including SDK and curl defaults — passes.

Auth state	Response
No `X-API-Key` header	`401` `MISSING_API_KEY`
Key without `read:checkins`	`403` `insufficient_scope`
Key with `read:checkins`	`200`

Filters

Parameter	Type	Notes
`restaurant`	UUID	Returns check-ins at any location of this restaurant.
`location`	UUID	Returns check-ins at this specific location.
`created_after`	ISO 8601 timestamp	Visits created on/after this instant. Epoch seconds rejected.
`created_before`	ISO 8601 timestamp	Visits created before this instant.
`page`	integer	Zero-indexed. Default `0`.
`page_size`	integer	Default `50`.

Combinations AND together. ?restaurant={uuid}&created_after=2026-06-01T00:00:00Z returns only that restaurant’s check-ins since the cutoff.

Tasting note - The filter key is the bare resource name, same trap as /memberships: restaurant, not restaurant_id. Unknown filter names (restaurant_id, location_id, user, user_id) are silently ignored and return the unfiltered set. A well-formed UUID that matches nothing is not an error — it returns 200 with an empty list and total_count: 0.

Example

curl "https://api.staging.blackbird.xyz/flynet/v1/check_ins?restaurant={uuid}&created_after=2026-06-01T00:00:00Z" \
  -H "X-API-Key: $API_KEY"
