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:A route handler, a job or a queue worker calls it the same way.
scripts/get-photo-feed.ts
Terminal
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
row.id as id. See Find an id.

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).Always sent. Its title: the name it goes by in every list, and the heading of its page where it has one.
Always sent. The URL name: lowercase words joined by hyphens (letters outside a–z, even emoji, are kept).
Always sent. Select whether this content is public or private. One of
public, loginRequired; a newer site may send others, so keep a fallback.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.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.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/…”).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.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.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.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.Sometimes sent:
undefined when the site leaves it out, and it can be null. From. Format: an ISO 8601 date (YYYY-MM-DD).Sometimes sent:
undefined when the site leaves it out, and it can be null. To. Format: an ISO 8601 date (YYYY-MM-DD).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.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.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.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.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.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.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.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.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.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.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.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.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.Sometimes sent:
undefined when the site leaves it out, and it can be null. Set automatically. The schedule paces the next refresh off this.Sometimes sent:
undefined when the site leaves it out, and it can be null. Last result.Sometimes sent:
undefined when the site leaves it out, and it can be null. Photos showing.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.Errors
Errors
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).
The site refused what was sent:
errors lists each field’s problem, siteMessage the first.Retried first: No. Read: errors (field → messages), siteMessage.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.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.Nothing matches, or the caller may not see it.Retried first: No. Read:
siteMessage, errorName, data.The site failed. Its logs say why.Retried first: No (only a 502, 503 or 504 is retried). Read:
siteMessage, errorName, data.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.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 status, or a success whose JSON doesn’t match this SDK version’s types (update the SDK).Retried first: No. Read:
reason, status.sites.forSite('acme') named a slug your sites (createSiteClients()) don’t have.Retried first: No: nothing was sent. Read: message, slug.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 seeRateLimitedonly 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.

It calls the function above with a fake client: the fake answers every call with a valid example, so nothing leaves your machine and no settings or key are needed. Run it withnode --test.
