How health is measured
  • Health = the share of calls that returned data, in percent. Empty results, failures and unknown outcomes do not count as returning data.
  • Levels: 90% and above is healthy, 70% and above is available, 40% and above is limited; anything lower is mostly down.
  • A period (the last 24 hours, one hour or one day) gets a score only once it has at least 50 calls. Periods with fewer calls show as normal: a few failures among a handful of calls do not mean the API is down.
  • Calls include real customer calls and our own daily probe calls. Request errors (wrong parameters, no balance) are excluded.
  • Average time counts only calls that completed normally: response time for sync calls, acceptance to completion for async ones.

Response example

Real response

Captured September 26, 2026 at 08:56 (UTC) by calling this API with the parameters in the code sample above. results and count are that call's real response with personal information (names, handles, avatars, profile links, contact details) removed; the list keeps the first 2. id, billing and quota differ on every call, so only their shape is shown.

Response fields

Business data is in results. The table lists the fields a record can contain; values the source does not provide are never made up.

FieldMeaning
nameName of the object itself, for account, product and business capabilities.
slugKeeps the platform's own meaning
urlLink to the record on the source platform.
descriptionSummary or description, usually shorter than text.
vendor_nameKeeps the platform's own meaning
vendor_slugKeeps the platform's own meaning
categoryCategory name in the source platform's own taxonomy, not normalized across platforms.
category_slugKeeps the platform's own meaning
ratingRating. The scale varies by platform: rating_scale on the same row gives the maximum (usually 5; Booking, Douban, iQIYI and NAVER use 10). Convert with rating_scale before comparing across platforms, or the comparison can come out backwards.
rating_scaleMaximum of rating in the same row: 5 for five-star scales, 10 for ten-point scales. Present only when the row has a rating.
rating_out_of_tenKeeps the platform's own meaning
review_countNumber of reviews, for product and business capabilities. null means not disclosed, not 0.
entry_level_priceKeeps the platform's own meaning
rankKeeps the platform's own meaning
pageKeeps the platform's own meaning
is_sponsoredKeeps the platform's own meaning
awardsKeeps the platform's own meaning
image_urlImage link. Capabilities with several images may return an image_urls array.
platformSource platform identifier, the same as platform in the request (for example xiaohongshu, tiktok).

Errors and billing

401
Missing or invalid key. Authentication runs before parameter checks, so unauthenticated requests never see the parameter schema.
422
Wrong parameter name or value. The error lists the parameters and allowed values this capability accepts and the closest match; it happens before any charge.
402
Insufficient balance. Top up first.
429
Per-minute request limit reached. Wait for Retry-After and try again.
503
Could not complete right now. Any charge for the call goes back to your balance automatically, and the billing receipt in the response states the actual outcome, including when it is not yet known. Do not resend blindly.
200 empty
The request completed without data and is not charged (billing.reason = empty_result_refunded).
