On Page API

Get On Page data as clean JSON with one key: 1 endpoint, 2 credits per call, the same response shape as every other platform.

What you get#

Onekey exposes On Page as 1 endpoint behind one API key: 1 endpoint return one record (data is an object). Every answer uses the same envelope (success, data, metadata, error), the cost is reported in metadata.credits_charged, and fields are mapped onto the unified schema so the code you write for On Page also works for the rest of the ai & search category.

Endpoints#

EndpointWhat it doesParametersCreditsStatus

A * marks a required parameter. Each endpoint name links to its reference page with the full parameter table, caching window and a recorded response.

Make a request#

This calls on_page.page (2 credits, beta). Replace YOUR_API_KEY with your key; sign up, no card. 1,000 free credits cover the open-platform endpoints. Hard-to-reach platforms (X, TikTok, Instagram, Reddit, and others marked on their page) need a verified email and a purchased pack.

curl "https://api.onekey.dev/v1/on_page/page?url=https%3A%2F%2Fexample.com%2F" \
  -H "x-api-key: YOUR_API_KEY"

Fields you get back#

These unified fields come back from On Page, with the same names as on every other platform. The count is how many of its 1 mapped endpoints return the field; a field the source lacks is null, never missing. 7 platform-specific fields (ext.<name>) come on top, documented on each endpoint page.

Pricing#

Every On Page endpoint costs 2 credits per call. Free when served from cache (0.2 credit for a cached response over 100 KB). Invalid, failed or not-found calls are not charged. See pricing for credit packs.
