itunes.lookup_podcast_episodes

stable Advanced

Recent episodes of an Apple Podcasts show (first row is the show).

GET /v1/itunes/lookup_podcast_episodes

What you get#

A list of Itunes results in Onekey's unified shape, in data (an array). An empty array is a normal, successful answer and is charged like any other; a source that reports "nothing found" as an error returns a free 404 not_found instead.

What it costs#

Advanced · 5 credits for a fresh fetch, charged only when it succeeds.
Free when served from cache (0.2 credit for a cached response over 100 KB).
Free if the request is invalid (never charged) or the source fails or reports not found (refunded).

Parameters#

Name	Type	Required	Default	What it is	Constraints
`id`	string	yes	(required)	iTunes/Apple id	max 12 chars; must match `[0-9]{1,12}`; trimmed
`country`	string	no	`us`	2-letter store country, e.g. us	max 2 chars; must match `[a-z]{2}`; trimmed, lowercased

Request#

curl "https://api.onekey.dev/v1/itunes/lookup_podcast_episodes?id=1200361736" \

Field mapping#

How this endpoint's source fields become Onekey's unified schema. Fields the source lacks come back as null.

Source path	Onekey field	Transform
`trackId`	`content.id`	`toString`
`trackName`	`content.title`	-
`description`	`content.text`	-
`trackViewUrl`	`content.url`	`safeUrl`
`episodeUrl`	`media.previewUrl`	`safeUrl`
`trackTimeMillis`	`ext.durationMs`	`toNumber`
`releaseDate`	`content.createdAt`	`toIsoDate`
`artistName`	`author.displayName`	-

Caching and freshness#

Fresh for about 1 hour. Repeat calls in that window are served from cache and are free.
Between 1 hour and 1 day the cached copy is still served instantly and marked stale: true while Onekey refreshes it in the background.
If the source is down when a refresh is needed, the last copy can be served for up to 3 days more (marked stale).
A "not found" is remembered for 5 minutes and is free.
The cache is shared across all customers, which is what keeps repeat calls cheap.

What can go wrong#

Status	Code	What to do
401	`unauthorized`	Check the `x-api-key` header.
402	`insufficient_credits`	Add credits; your balance must cover the price.
404	`not_found`	Unknown endpoint path.
422	`invalid_params`	Fix the parameters using the table above. Free.
429	`rate_limited`	Wait `Retry-After` seconds, then retry.
502	`upstream_error`	The source failed. Refunded; retry with backoff.

See Errors for the full list and retry guidance.
