# /nhk/articles

`POST /api/nhk/articles`

Price: 5 credits

Get a full NHK news article by id or URL: headline, teaser, the complete body text in plain and markdown form, publish and update time, genre, region, topic tags, lead image, on-demand video with direct HLS stream links and duration, table of contents for live-updated articles and the list of related articles.

## How to use it

Fetch one NHK article by its id (na-…, nb-… or nc-…) or by pasting a news.web.nhk article URL; a legacy www3.nhk.or.jp/news/html/<date>/k…….html URL and a bare k……… id also resolve. Returns one item with article_title (the short headline the site shows), document_title (the longer descriptive title, different on roughly two thirds of articles), description, text (full plain-text body), body_markdown (same body with headings and inline images), lead, published_at (the true first-publication moment, which the feeds do not carry) and updated_at (unix seconds), genres, genre_id (usable as the genre filter in nhk/articles/search), area_id (regional articles, usable as the area filter), topics with ids usable as the topic filter, playlist_id (usable in nhk/playlists), image, videos with direct HLS stream urls and duration in seconds, sections (table of contents of live-updated articles) and related_articles.

## Errors

### 422 — Validation Error

The request body did not validate

What to do: Check the fields against this schema. A URN with the wrong prefix is the most common cause.

- `detail` (array)
  - `loc` (array, required)
  - `msg` (string, required)
  - `type` (string, required)
  - `input` (any)
  - `ctx` (object)

### 408

The request ran past its time limit

What to do: Raise `timeout` in the request body, up to the maximum this endpoint documents. Lowering `count` or turning off the `with_*` flags also helps, because less work finishes sooner.

### 412

Article not found — the id or URL does not resolve to an NHK article

What to do: Retrying will not help: either the entity does not exist, or the input points at a different one.

### 429

Too many requests: a rate limit or a usage window is exhausted

What to do: When the response carries an X-Retry-After header, wait that many seconds and retry: the same number is in the body as `detail.retry_after`, and the limit clears once that window passes. The message in the body names the limit that was hit.

### 500

Something broke on our side

What to do: Retrying will not help. If it keeps happening, send us the X-Request-ID from the response headers.

### 529

Rate limit reached, or the endpoint is overloaded

What to do: Wait at least 30 seconds, then retry.

## Response envelope

Success: Array of objects (may be empty if no results)

Error: Error may coexist with partial results if it occurs mid-execution. Check X-Error header and status code.

Every response carries these headers:

- `X-Error` — Error message text (present only on error)
- `X-Request-ID` — Unique request identifier
- `X-Execution-Time` — Execution time in seconds
- `X-Result-Count` — How many records the body carries. 0 means an empty result, which is a normal answer and not by itself an error. A non-zero count can come back together with X-Error when the failure happened partway through — read this header and X-Error independently.
- `X-Total-Available-Results` — How many records exist for this query, when the endpoint can say. On a `dry_run` request this is the answer and the body is empty. It saturates: the endpoint's documented maximum means 'at least that many', any smaller number is exact.
- `X-Warning` — Present when the request body carried keys this endpoint does not document. They were ignored, so any filter you meant to apply through them did not apply. Check the spelling against this schema and retry.
- `X-Retry-After` — Seconds to wait before retrying. Present only on 429.
