What is the When Is The Next MCU Film API?

The When Is The Next MCU Film API is a free, key-free endpoint that returns how many days remain until the next Marvel Cinematic Universe release, along with its title, overview, poster image and release date, and the same details for the production after it.

This is a single-endpoint API and the shape reflects it: the next production is the top-level object itself, not nested under a key, with the one after it tucked into `following_production`. That flatness is convenient right up until you write a loop expecting a list, so read it as a two-element structure rather than a collection. `days_until` is computed server-side, which means the value is correct at the moment of the request and stale the next day.

Do not be fooled by the name. The `type` field in our capture returned `TV Show` for the next release and `Movie` for the one after, because the API tracks Disney+ series alongside theatrical films. Anything that says 'next film' in your UI will eventually be wrong. Ids are TMDB ids and poster URLs point at TMDB's w500 CDN, so linking out to a fuller record needs no extra lookup — though it does mean TMDB's attribution terms apply to the imagery.

Response fields

days_untilinteger: Whole days until the next release, computed server-side at request time. Recompute or refetch daily.
titlestring: Name of the next production. It sits at the top level, not inside a wrapper object.
typestring: `Movie` or `TV Show`. Despite the service's name, Disney+ series are included and are frequently the next release.
release_datestring: ISO `YYYY-MM-DD` date — genuinely parseable, unlike `days_until`, which is a derived value.
idinteger: TMDB id for the production, letting you link out or fetch a fuller record without a name search.
overviewstring: A short synopsis, sourced from TMDB.
poster_urlstring: Absolute TMDB image URL at w500 width. TMDB's attribution terms apply if you display it.
following_productionobject: The release after next, carrying the same field set including its own `days_until`.

Common errors and how to fix them

Stale days_until

The value was computed when you fetched it, not when you rendered it.

Fix: Cache for a few hours at most, or store `release_date` and compute the countdown client-side from the current date.

A TV series where you expected a film

The API tracks Disney+ shows as well as theatrical releases.

Fix: Read `type` and label your UI accordingly, or filter to `Movie` and use `following_production` when the next entry is a series.

A broken poster image

The TMDB CDN path changed, or the production has no artwork yet.

Fix: Guard against an empty or unreachable `poster_url` and fall back to a placeholder; unannounced projects often have none.

When Is The Next MCU Film API — frequently asked questions

Does the MCU countdown API need an API key?

No. It is a single public endpoint with no parameters, no key and no account. One GET returns the next release and the one after it.

Does it include Disney+ series or only films?

Both. The `type` field distinguishes `Movie` from `TV Show`, and a series is often the next release, so a UI that only ever says 'film' will be wrong periodically.

Where does the data come from?

TMDB. The `id` is a TMDB id and `poster_url` points at TMDB's image CDN, so you can link out to a full record without a search — and TMDB's attribution terms apply to any imagery you display.

How often should I call it?

At most a few times a day. `days_until` changes once per day and release schedules move rarely, so caching for several hours costs you nothing in accuracy.
