FAXTR
16 East 34th Street, New York, NY 10016
What it is
FAXTR is a fact-checking service for claims, headlines, articles, article URLs, and LLM-generated text. It aggregates verdicts from more than 100 fact-checking organizations across over 50 countries, leaving the judgment of whether a claim is true or false to the user. The website offers three checks without sign-up; registration allows more checks and history. Its data collection uses the Google Fact Check Tools API and Google News RSS, which FAXTR says are fetched three times daily. The REST API returns JSON at https://api.faxtr.com/v1, though verification endpoints are in private beta and require access. The API includes a /v1/guard endpoint for scanning LLM responses for misinformation. FAXTR Verified records a source organization, receipt details, text and debunk matches, and a published SHA-256 fingerprint of an article body. Publishers can integrate it using one server-rendered link per article, without JavaScript or a runtime dependency on FAXTR. The Free plan costs nothing and includes 1,000 API calls per month, a limit of 10 requests per minute, and community support. Starter costs $49 a month and includes 25,000 API calls monthly, all search endpoints, and single-claim verification.

The verdict
FAXTR brings together existing fact-check verdicts rather than issuing its own conclusion. Readers should note the website’s limited unsigned checks and that API verification requires access; paid plans start at $49 a month.
Who it suits
It suits readers checking claims against existing fact-checks and developers or publishers considering verification tools. API verification endpoints require private-beta access.
