Discovery/recommendations

Titles similar to one or more seed titles, scored 0-1 and above a fixed threshold. Spends no verification.

Parameter

• seedsstringerforderlich

  Comma-separated title ids or UUIDs to find neighbours of, 1-10.

  Mehr⌄

  Comma-separated title ids. Between 1 and 10.

• languagestringoptional

  Response language, a supported BCP-47 tag. Default en.

  Mehr⌄

  A supported BCP-47 tag. Defaults to en. An UNSUPPORTED tag is a 400 naming the accepted set, never a silent fallback - the catalogue stores match the 17 tags as exact strings, so degrading would answer an empty 200 that an integrator would ship before noticing.

• exclude_seenbooleanoptionalStandard: true

  true (default) leaves the seed titles themselves out of the results.

  Mehr⌄

  Whether the SEED titles themselves are left out of the results. true by default; false lets a seed appear when it is also a strong neighbour of another seed.

• excludestringoptional

  Comma-separated title ids never to return, up to 100.

  Mehr⌄

  Comma-separated title ids to suppress, supplied by the caller.

• limitintegeroptionalStandard: 10

  Results, 1-50. Default 10.

  Mehr⌄

  How many recommendations to return, 1-50. Default 10. There is no cursor; ask for more by raising this.

Antwortfelder

• totalinteger · int64kann null sein

  How many items the query matches in total, when that is known. Null when it is not known; it is never an estimate.

Antwort-Header

• X-Request-ID

  The id of this request, on every response - success or error. Quote it to support: it is how we find your request in our logs. An X-Request-ID you send is honoured and echoed back, so you can use your own; otherwise we generate one. /v1 error bodies carry no trace id of their own.

• X-Quota-Reset

  RFC 3339 instant at which the billing period rolls. Present on every response to a request whose key was metered - every 2xx, every error a handler returned, and the quota 429. Absent on a refusal that happens before metering: a missing or unknown key (401), a restricted key or a plan that does not carry the endpoint (403), a public demo-key gate refusal, and the pre-authentication flood throttle.

• X-Calls-Remaining

  Requests left in the period after this one, never below 0. Present whenever X-Quota-Reset is (see there for when a response carries no quota headers).

• X-Verifications-Remaining

  How many verifications you can still make before a limit stops you. The daily limit and the monthly allowance are counted separately; this is whichever of the two runs out first. Sent whenever X-Quota-Reset is.

• X-Quota-Grace

  true when THIS request fell inside the 10% grace band above a monthly ceiling. A grace request is served and is not billed; treat true as "back off now", not as headroom. Always true or false, never absent when the other quota headers are present.

• Retry-After429

  Seconds to wait before retrying. On every 429 - the quota hard stop, the public demo key's limits, and the pre-authentication flood throttle (which carries this header alone, because no key has been read yet).

• X-Demo-Challenge-ModeNur mit dem Demo-Schlüssel

  Sent only on responses to the public demo key. The value interactive asks the documentation page to show the visible verification widget - it is sent once a browser has made more than five runs in ten minutes or has received a 429. The page then repeats the header, X-Demo-Challenge-Mode: interactive, on its next request, with the widget's token in X-Demo-Challenge. Requests made with your own key never receive it.
