FAQ
We're here to help
WebCite is an AI-powered citation and fact-verification API. Enter any claim, and we search authoritative sources (journals, news, government records) to find citations, analyze their stance (supports/contradicts), and generate a verification verdict. Use our REST API or real-time streaming (SSE) to integrate fact-checking into your applications.
Each verification includes three components: 1. Citation Search - Find relevant sources with credibility scores 2. Stance Analysis - Determine if sources support or contradict the claim 3. Verdict - Get an overall verification result (supported, contradicted, mixed, unverifiable) You can skip stance or verdict to save credits when you only need citations.
Credits are consumed per operation: citation search costs 2 credits, stance analysis costs 1 credit, and verdict generation costs 1 credit. A full verification (all three) costs 4 credits total. You can save credits by skipping stance or verdict when you don't need them.
Generate an API key from your dashboard and make REST calls to our endpoints. We support both synchronous responses and real-time streaming via Server-Sent Events (SSE) for live updates as citations are found. Check our API docs for code examples in JavaScript, Python, and cURL.
On the Free plan, you'll need to wait until the next month. On the Builder plan ($20/month), you can continue using the API with usage-based billing at $0.03 per additional credit. Enterprise plans include custom allocations.
Enterprise includes: 10,000+ credits/month, bring your own organizational data, data integrations (Google Drive, SharePoint, S3), custom fields & citation logic, SSO/SAML authentication, dedicated account manager, and custom SLAs.
Yes. All data is encrypted in transit and at rest on enterprise-grade cloud infrastructure. We don't store your verification queries beyond processing. Enterprise customers can use their own data sources with granular access controls.
