Google Fact Check Tools API - search fact-check claims and their ratings from reputable publishers across the web.
Bring your own key. This API needs your own Google Fact Check Tools API key - get one from the provider, add it once below, and the proxy injects it on every call. Your OmniStream plan covers the unified SDK, key storage, and proxy - the provider's own rate limits still apply to your key.
This is a community listing. If you own this API, you can request ownership.
npm install omnistream-sdkimport { OmniClient } from "omnistream-sdk";
const omni = new OmniClient({ token: process.env.OMNI_KEY! });
// One key reaches every API on the marketplace.
const data = await omni.call("google-factcheck/factchecktools.claims.search");One install, one key - the same client calls every API on the marketplace.
V1 error format.
OAuth access token.
Data format for response.
JSONP
Selector specifying which fields to include in a partial response.
API key. Your API key identifies your project and provides you with API access, quota, and reports. Required unless you provide an OAuth 2.0 token.
OAuth 2.0 token for the current user.
Returns response with indentations and line breaks.
Available to use for quota purposes for server-side applications. Can be any arbitrary string assigned to a user, but should not exceed 40 characters.
Upload protocol for media (e.g. "raw", "multipart").
Legacy upload protocol for media (e.g. "media", "multipart").
The BCP-47 language code, such as "en-US" or "sr-Latn". Can be used to restrict results by language, though we do not currently consider the region.
The maximum age of the returned search results, in days. Age is determined by either claim date or review date, whichever is newer.
An integer that specifies the current offset (that is, starting result location) in search results. This field is only considered if `page_token` is unset. For example, 0 means to return results starting from the first matching result, and 10 means to return from the 11th result.
The pagination size. We will return up to that many results. Defaults to 10 if not set.
The pagination token. You may provide the `next_page_token` returned from a previous List request, if any, in order to get the next page. All other fields must have the same values as in the previous request.
Textual query string. Required unless `review_publisher_site_filter` is specified.
The review publisher site to filter results by, e.g. nytimes.com.
Search through fact-checked claims.
List the `ClaimReview` markup pages for a specific URL or for an organization.
Create `ClaimReview` markup on a page.

No reviews yet. Be the first to rate this API.
Yes. Google Fact Check Tools API uses apiKey authentication, so you bring your own key from the provider. You store it once on OmniStream and the proxy injects it into every call, so your code only ever sends your Omni key.
Google Fact Check Tools API - search fact-check claims and their ratings from reputable publishers across the web. It exposes 6 endpoints over GET, POST, PUT, DELETE, including GET /v1alpha1/claims:search, GET /v1alpha1/pages, POST /v1alpha1/pages.
Install the OmniStream SDK for your language and call Google Fact Check Tools API through it. The client is generated from this API's OpenAPI spec, so parameters and responses are fully typed, and the same client also calls every other API in the marketplace.
You can start on the free plan. OmniStream charges for the unified SDK, key storage and proxy rather than for Google Fact Check Tools API itself, and Google Fact Check Tools API's own rate limits still apply to your provider key.
