POST /api/fourchan/boards/search
Price: 1 credit
List 4chan's boards with their slug, title, description and posting rules: page count, threads per page, bump and image limits, file size and comment limits, posting cooldowns, whether the board is work-safe, keeps an archive, shows poster ids or country flags, and its board-flag codes
Start here: every other 4chan endpoint needs a board slug, and `alias` is that slug. `has_archive` tells you whether a board's dead threads survive a few days more, so it narrows which boards fourchan/threads/archive serves without promising it — `/r/` declares an archive and is refused there. `shows_poster_ids` and `shows_country_flags` explain why `poster_id` and `country` are populated on some boards and absent on the rest, and `board_flags` maps that board's flag codes to their labels. `query`, `worksafe_only` and `archived_only` are applied to the directory after it is read, so they never reach 4chan as a search.

A URN with the wrong prefix is the most common cause.408 — The request ran past its time limit 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 — The entity was not found, or a precondition failed 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 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 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 Wait at least 30 seconds, then retry.X-Error — Error message text (present only on error)X-Request-ID — Unique request identifierX-Execution-Time — Execution time in secondsX-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.
