API security is broadly required in cloud and backend JDs; OWASP API Top 10, OAuth2/OIDC, and rate-limiting appear routinely in postings from major employers and vendors.
(0.80)
“API Security” is a specific security domain focused on securing APIs; it’s unlikely to be confused with other distinct catalog skills.
Not versioned
Domain ·security confidence 0.93
API Security is best treated as a domain because it is a vertical body of knowledge about securing APIs rather than a single tool, protocol, or methodology.
