Get the full filter catalogue PC Koubou (パソコン工房) offers for a category or a free-text query: every maker, holding branch, merchandising label, campaign tag and category-specific specification value, each with the number of products behind it and the exact token to pass back to the search endpoint.

How to use it

Given a category such as '自作PCパーツ:グラフィックカード' from the categories endpoint, a keyword, both or neither, return every filter pc-koubou.jp supports for that scope. Each facet carries its key, a Japanese name where the source names it, the payload_field of the search endpoint it feeds, and its values with value, name, product_count and filter. Send a value straight into maker, store, labels, campaign_tags or item_type when payload_field says so; where payload_field is release_period send the value's filter token instead, because that field takes an English period name rather than the shop's Japanese wording; for everything else send the ready made filter token into specs. The specification facets differ from one category to another — a graphics-card branch offers chipset, bus and output filters while a machine branch offers OS, CPU and memory — so read them per category rather than assuming a fixed set.

Parameters

• access-token string required

Request body

Response

• @type string (default: "PckoubouProductFacets")
• category string nullable
• keyword string nullable
• product_count integer nullable
• facets array (default: [])

  • payload_field string nullable
  • values array (default: [])

    • value string required
    • name string nullable
    • filter string nullable
    • product_count integer nullable

Errors

• 422 — The request body did not validate Check the fields against this schema. 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 requested category or keyword matches no products on pc-koubou.jp 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.

Response 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.
