Record Class SecurityRequirement

java.lang.Object
java.lang.Record
org.a2aproject.sdk.spec.SecurityRequirement
Record Components:
schemes - map of security scheme names to lists of required scopes
public record SecurityRequirement(Map<String,List<String>> schemes) extends Record
Represents a security requirement in the A2A Protocol.

A SecurityRequirement defines which security schemes must be satisfied to access an agent or skill. It maps security scheme names to lists of required scopes. When multiple scheme entries are present in a single SecurityRequirement, ALL must be satisfied (AND relationship). When multiple SecurityRequirements are present in a list, any ONE may be satisfied (OR relationship).

This class corresponds to the SecurityRequirement type in the A2A Protocol specification, which contains a schemes field mapping scheme names to scope arrays.

Example usage: 


 // Single OAuth2 requirement with specific scopes
 SecurityRequirement oauth2Req = SecurityRequirement.builder()
     .scheme("oauth2", List.of("read", "write"))
     .build();

 // API key requirement with no scopes
 SecurityRequirement apiKeyReq = SecurityRequirement.builder()
     .scheme("apiKey", List.of())
     .build();

 // Combined requirement: both OAuth2 AND API key required
 SecurityRequirement combinedReq = SecurityRequirement.builder()
     .scheme("oauth2", List.of("profile"))
     .scheme("apiKey", List.of())
     .build();
