Apple Podcasts has four public JSON APIs, no key required — and a fifth everyone assumes exists

Scraping Apple Podcasts looks like a browser job. The web player is a JavaScript app, show pages render client-side, and the reflex is to reach for Playwright.

You don't need it. Everything worth having sits behind four public JSON endpoints that take no key, no token and no cookie, and answer a plain GET from any IP. We built an Apple Podcasts scraper on exactly these — HTTP-only, no headless browser anywhere.

Here's the map, and the two failure modes that will ship silently if you don't look for them.

1. Charts

https://rss.marketingtools.apple.com/api/v2/us/podcasts/top/50/podcasts.json
Enter fullscreen mode Exit fullscreen mode

Swap us for any storefront (gb, de, jp). Returns feed.results as an ordered array — the rank is the array position, there is no rank field, which is easy to lose if you map the objects and drop the order. feed.updated carries a real freshness stamp; when we pulled it while writing this it was about a minute old.

Rows are thin: id, name, artistName, url, genres, artworkUrl100. No feed URL, no episode count, no description — join on id against endpoint 3 for those.

2. Search

https://itunes.apple.com/search?term=true+crime&media=podcast&country=us&limit=25
Enter fullscreen mode Exit fullscreen mode

The old iTunes Search API is still up and still free. media=podcast returns full show records — same shape as lookup — so a search doubles as a metadata fetch. No second call per hit.

3. Show metadata

https://itunes.apple.com/lookup?id=1434243584&country=us
Enter fullscreen mode Exit fullscreen mode

One full record: collectionName, artistName, primaryGenreName, genres, trackCount, releaseDate, artworkUrl600, content advisory — and feedUrl, the publisher's actual RSS feed, if you want to leave Apple's ecosystem entirely.

4. Episodes — the one that saves the most work

https://itunes.apple.com/lookup?id=1434243584&country=us&entity=podcastEpisode&limit=100
Enter fullscreen mode Exit fullscreen mode

One request returns the show record and its recent episodes together. In our check, limit=5 came back with resultCount: 6 — one wrapperType: "track" (the show) plus five wrapperType: "podcastEpisode" rows. Always filter on wrapperType instead of assuming results is homogeneous, and note you get the show metadata free in the same response.

Each episode row carries ~26 fields, and the valuable one is episodeUrl: the direct audio file. Not a player page — the actual MP3, usually on the publisher's CDN. Watch the naming: there is no audioUrl. The MP3 is episodeUrl, the human-readable Apple page is trackViewUrl. We had these backwards on the first pass and only caught it by reading a real output row instead of trusting the field name we expected.

limit caps out well short of "every episode ever", so treat this as a recent-episodes feed. For a full back catalogue, take feedUrl and parse the publisher's RSS.

5. Reviews, and why the feed looks broken when it isn't

https://itunes.apple.com/us/rss/customerreviews/id=1434243584/sortBy=mostRecent/page=1/json
Enter fullscreen mode Exit fullscreen mode

Up to 50 entries per page, roughly 10 pages deep. Everything is wrapped in {"label": ...} objects, so plan on an unwrapping helper, and when a feed has exactly one review, feed.entry is an object, not an array — normalize it or your .map() throws.

The real trap: this feed is full of holes. For a given id/storefront/sort, some page numbers return a well-formed but empty feed while later pages return a full 50 — page 1 empty and page 5 full is common. It's sticky rather than random (repeat the request, get the same empty result), which is exactly why it reads as an outage and sends people hunting for a fingerprinting fix.

The fix is not a browser and not UA rotation. Scan the whole 1–10 page range and skip the holes instead of breaking on the first empty page, then dedupe by review id. If you break on empty — which is the natural way to write pagination — you will conclude a show has zero reviews when it has hundreds.

(There is a second, separate effect: an iPhone/iPad User-Agent gets a different, independently paginated index over the same review pool. On one title, a curl sweep and an iOS sweep returned 50 and 200 unique reviews with zero overlap. Union both if you want maximum coverage.)

The endpoint that doesn't exist: genre charts

Every few weeks someone wants "top 50 Comedy podcasts in Germany". It looks like it should work — Apple has genre IDs, they appear in every record, and the older iTunes RSS generator did have genre-scoped chart feeds. So people guess at URLs. We tried the plausible shapes:

URL shape Result
.../top/5/genre=1489/podcasts.json 404
.../top/5/1489/podcasts.json 404
.../top-shows/5/genre=1489/podcasts.json 404
.../top/5/podcasts.json?g=1489 200 — same list, same order as the unfiltered chart

That last row is the whole problem. The query-param form doesn't error. It silently ignores your filter and hands back the overall chart. Build a "top comedy podcasts" pipeline on it and you get a plausible 200 with completely wrong data and no signal anything went wrong.

We proved it by diffing the two responses: same ids in the same order, and identical field-for-field once you drop feed.updated — which is a per-second freshness stamp, so a naive byte-comparison of two sequential requests can disagree for reasons that have nothing to do with your filter. That's worth knowing before you build the diff check this post is about to recommend: strip the timestamps before you compare, or you'll conclude a parameter worked when it did nothing.

There is no public deep-genre chart. The honest path is to pull the overall chart, join each id against lookup, and filter on primaryGenreName — accepting you can only surface genre leaders that already rank overall.

One more silent one: an invalid storefront (.../api/v2/zz/...) returns HTTP 500 with an HTML error page, not a JSON error. Pipe that straight into a JSON parser and your user gets a SyntaxError about an unexpected <, which tells them nothing about the actual problem — their country code. Sniff the status or content type first.

The general lesson

Two of the five findings above are negative results, and both would ship silently: the genre chart that 200s with wrong data, and the review pagination that reports zero because you stopped at the first hole.

When you're mapping an undocumented API, a 200 is not evidence that your parameter did anything. Change the parameter, diff the response against the unparameterized call, and if they're identical your filter was ignored. Same discipline on pagination: prove an empty page means "end of data" before you let it terminate your loop.
