hackernews.search_by_date

stable Advanced

Search Hacker News stories, newest first.

GET /v1/hackernews/search_by_date

What you get#

A list of Hacker News 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.

Pagination: 20 results per page. The response carries a pagination block; send its next_cursor back as the cursor parameter to get the next page. Every page is one call at the price below. See Pagination.

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
`q`	string	yes	(required)	Search query	max 200 chars; trimmed, repeated spaces collapsed
`cursor`	string	no	-	Opaque cursor from a previous response's `pagination.next_cursor`. Omit for the first page.	-

Request#

curl "https://api.onekey.dev/v1/hackernews/search_by_date?q=startup" \

Building stuff and throwing it out into the void is very intimidating and I was starting to get disheartened. What kind of small successes have you had that you want to celebrate?",

There are a bunch of easter eggs and a lot to learn about video games. Enjoy the exhibits.",

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
`objectID`	`content.id`	-
`author`	`author.username`	-
`title`	`content.title`	-
`url`	`content.url`	`safeUrl`
`story_text`	`content.text`	`stripHtml`
`created_at`	`content.createdAt`	`toIsoDate`
`points`	`engagement.likes`	`toNumber`
`num_comments`	`engagement.comments`	`toNumber`

Caching and freshness#

Fresh for about 2 minutes. Repeat calls in that window are served from cache and are free.
Between 2 minutes and 15 minutes 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 1 hour more (marked stale).
A "not found" is remembered for 1 minute 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.
