In your app

A function makes the call on the client it is given, so your code passes the real one and a test passes a fake.

Add the function

src/attract/get-photo-feed.ts

Call it

A script makes the client once and calls the function:
scripts/get-photo-feed.ts
Terminal
A route handler, a job or a queue worker calls it the same way.

Find the id

id is the document’s _id, from a list. Ask the list for only the fields you need: each row is a document’s id and those fields.
TypeScript
Pass row.id as id. See Find an id.

Required parameters

One object, e.g. getPhotoFeed({ id }); leave out the optional fields.
string
required
Required. The document’s _id: a full id names its own locale and mode (the draft’s …:en:draft, the published one’s …:en:published; no aposMode needed), a bare aposDocId takes the request’s (aposLocale, aposMode).
boolean | null | undefined
Optional. Leave it out and the site uses false. true: each area’s widgets come back rendered as HTML (_rendered), beside their data.
A PhotoFeed. PhotoFeed content type. Read its properties (photoFeed.title): each says whether the site always sends it. The example answer is the site’s wire JSON: one key differs from the property names (_id → id).
string
Always sent. Its title: the name it goes by in every list, and the heading of its page where it has one.
string
Always sent. The URL name: lowercase words joined by hyphens (letters outside a–z, even emoji, are kept).
Visibility
Always sent. Select whether this content is public or private. One of public, loginRequired; a newer site may send others, so keep a fallback.
string
Always sent. The document’s id. On a type with drafts it ends in its locale and mode (…:en:published, …:en:draft): the part before the first colon is its aposDocId, shared by both copies. The {_id} the type’s routes take.
string
Always sent. The document type’s name: always this type’s.
Date
Always sent. When it was created (ISO 8601). Format: an ISO 8601 date and time.
Date
Always sent. When it last changed (ISO 8601). Format: an ISO 8601 date and time.
string | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Which external photo store to draw from. Connections (bucket, region, keys) are set up once in Connections → Photo storage.
string | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Optional. The folder inside the bucket the dated folders live under — leave empty when they sit at the top level (e.g. “2026/May/31/…”).
FeedLayout | null
Sometimes sent: undefined when the site leaves it out, and it can be null. How deep the dated folders go. The month and day folder NAMES don’t matter — “May”, “05” and “5” are all understood — only the depth. One of ymd, ym, y, flat; a newer site may send others, so keep a fallback.
FeedDateRule | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Which dates this feed is allowed to pull from. Only the folders inside this window are ever listed, so a huge library stays cheap to sample. One of recentDays, thisYear, lastYears, range, all; a newer site may send others, so keep a fallback.
number | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Counting today. 5 means today and the four days before it. 1 to 365.
number | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Counting this one. 2 means this calendar year and last. 1 to 25.
Date | null
Sometimes sent: undefined when the site leaves it out, and it can be null. From. Format: an ISO 8601 date (YYYY-MM-DD).
Date | null
Sometimes sent: undefined when the site leaves it out, and it can be null. To. Format: an ISO 8601 date (YYYY-MM-DD).
FeedDistribution | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Spread samples one target count across as many different days as possible (best for a wide window). Every day takes the same number from each day in the window (best for a daily-update wall). One of total, perDay; a newer site may send others, so keep a fallback.
number | null
Sometimes sent: undefined when the site leaves it out, and it can be null. How many photos this feed shows. Each refresh replaces the whole set. 1 to 500.
number | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Taken from every day in the window — 10 from each of the last 5 days is 50 photos. 1 to 200.
boolean | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Remember which photos were used and prefer ones that haven’t been shown lately, so a big library keeps producing new sets. When a date window runs out of unseen photos it reuses the oldest ones rather than showing fewer.
number | null
Sometimes sent: undefined when the site leaves it out, and it can be null. The size of that memory. Bigger means longer before a photo can repeat; 0 turns the memory off. 0 to 20000.
FeedFormat | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Every photo is re-encoded on the way in — which also strips camera metadata (location, device) from what the site serves. One of webp, jpeg; a newer site may send others, so keep a fallback.
number | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Photos larger than this are scaled down. 2000 is plenty for a full-screen lightbox; the gallery tiles use much smaller generated sizes. 320 to 6000.
number | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Encoder quality, 40–100. 82 is a good balance; above 90 grows files fast with little visible gain.
FeedAspect | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Keep each photo’s own proportions (best for the Mosaic and Masonry layouts), or crop everything to one shape for a perfectly uniform wall. Crops are centered on the busiest part of the photo. One of original, 1:1, 4:3, 3:2, 16:9, 4:5; a newer site may send others, so keep a fallback.
string | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Optional. Describes what these photos generally show, for screen readers and the lightbox caption. Applied to each photo as it is imported — leave empty to import them without alt text.
boolean | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Master switch. When off, the feed keeps showing its current photos and only refreshes when you run it by hand.
FeedInterval | null
Sometimes sent: undefined when the site leaves it out, and it can be null. How often to fetch a fresh set. Change it anytime — no restart. One of 1, 2, 3, 4, 6, 12, 24, 48; a newer site may send others, so keep a fallback.
number | null
Sometimes sent: undefined when the site leaves it out, and it can be null. After a refresh the old photos stop being shown immediately, but their files are kept this long before being deleted — a safety margin for pages already sent to a browser and for CDN caches. 0 deletes them right away. 0 to 10080.
string | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Set automatically. The schedule paces the next refresh off this.
string | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Last result.
number | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Photos showing.
string | null
Sometimes sent: undefined when the site leaves it out, and it can be null. Why the last refresh failed, when it did. A failed refresh never empties the gallery — the previous photos keep showing.
boolean | null
Sometimes sent: undefined when the site leaves it out, and it can be null. In the archive: kept, but out of every list and off the site until it is restored. false (or null) for a live document.
Nothing to catch: the SDK retries what is safe, and throws the rest as the classes below; catch only what you want to react to (see Errors and testing).
400
The site refused what was sent: errors lists each field’s problem, siteMessage the first.Retried first: No. Read: errors (field → messages), siteMessage.
401
The API key is missing or refused (malformed, revoked, expired), or a signature its signing mode needs is missing or stale.Retried first: No. Read: siteMessage, errorName, data.
403
The key may not do this: a scope it lacks, or an address outside its allowlist. siteMessage names it.Retried first: No. Read: siteMessage, errorName, data.
404
Nothing matches, or the caller may not see it.Retried first: No. Read: siteMessage, errorName, data.
500
The site failed. Its logs say why.Retried first: No (only a 502, 503 or 504 is retried). Read: siteMessage, errorName, data.
no answer
No answer: DNS, a refused connection, TLS, or the timeout (15 s per attempt by default).Retried first: Yes, after 0.5 s then 1 s. Read: reason, neverConnected.
not sent
The client refused to send it (e.g. a path segment of ..); the site never saw it.Retried first: No. Read: reason (what to change).
any other
Any other status, or a success whose JSON doesn’t match this SDK version’s types (update the SDK).Retried first: No. Read: reason, status.
setup
sites.forSite('acme') named a slug your sites (createSiteClients()) don’t have.Retried first: No: nothing was sent. Read: message, slug.
setup
The client’s settings are wrong: no FETCHSKI_ATTRACT_URL (or baseUrl), or a malformed API key.Retried first: No: nothing was sent. Read: message (what to fix).

Behavior

  • Access: an API key with content:photo-feeds:read (or a master above it: content:photo-feeds:all, content:all, admin:all) reads the published documents. A signed-in person may call it as far as their own permissions allow; anyone else gets 404.
  • Rate limit: the key’s own reads-per-minute limit, set when the key is created (default 600); over it, 429 with Retry-After. The client waits and retries for you; you see RateLimited only if that runs out.
  • Retries: a read is safe to repeat: the client retries it on no answer, a 502/503/504 and a 429.
  • Timeout: 15 s per attempt by default; raise timeout (milliseconds) on the client for longer.
