Cohere's API documentation helps developers easily integrate natural language processing and generation into their products.
Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Page metadata, canonical configuration and social previews work together to provide more consistent search and sharing presentation.
Domain and Registration
Registered in 2000, this domain has about 26 years of history. That suggests continuity, although ownership and purpose may have changed. Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The registrar is Tucows Domains Inc., a widely used domain service provider. The domain uses the common .com extension, which is not an independent safety signal.
DNS and Email
Nameservers are provided by Cloudflare, indicating managed DNS hosting. MX records point to the Google Workspace email service. SPF and DMARC are configured. DKIM status is unknown. TXT records include verification markers for Google, Apple, Microsoft. Such markers may also remain after a service stops being used. DNSSEC signatures were not detected, so this additional DNS authenticity protection is not confirmed.
TLS and Certificates
The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. No organization name is present in the certificate; the available fields are consistent with domain validation. The certificate was issued by Let's Encrypt, commonly associated with automated certificate services. The certificate's total validity is about 89 days, consistent with a short renewal cycle.
HTTP and Browser Security
X-Powered-By exposes backend information: Next.js. The response lacks these common security headers: clickjacking protection. No obvious internal addresses or debug information were found in the headers. The Server header contains the custom value Vercel. No explicit CDN or WAF marker was found in the response headers.
Technology Stack Analysis
The public page identifies https://buildwithfern.com, Next.js, Vercel without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
The Generator tag identifies https://buildwithfern.com, making the publishing system easier to fingerprint. Open Graph is partially configured; og:type is missing. Twitter Card metadata is configured. The title has 29 characters, within a common display range. A meta description is present, with 124 characters.
