How this service works
Password - CASA Cybersecurity Assessment - Evaluates whether the service correctly follows UCP and AP2 protocols, including identity, negotiation, validation, transaction, and business rules. It combines evidence from discovery, authorization, checkout integrity, state transitions, and request validation.
Output
Returns a structured compliance report covering functional adherence to UCP and AP2 protocols, with findings across identity validation, authorization flows, checkout integrity, state transitions, request validation, and business rules — indicating pass/fail status and evidence for each assessed area.
Example use cases
Pre-launch API compliance audit
“Before we go live, run a CASA functional compliance check on our payment API to make sure it properly handles UCP and AP2 protocol flows — identity, authorization, and transaction validation in particular.”
Checkout integrity regression test
“After our recent checkout refactor, run a functional compliance assessment to verify that our state transitions, request validation, and business rules still pass CASA requirements.”
Third-party vendor due diligence
“I need to evaluate a vendor's API before integrating it — can you run a CASA functional compliance assessment to check how well they follow UCP and AP2 protocols, especially for identity negotiation and transaction rules?”
Technical details
Endpoint
POSThttps://billitright.co/run-functional_compliance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to assess the functional compliance layer of a service against UCP and AP2 protocols — covering identity, negotiation, transaction, and business rules. Prefer this over the full CASA suite when you want targeted functional compliance results without transport, header, or availability assessments.
Side effects
- Service URL unreachable or returns non-200 responses — assessment cannot gather evidence
- Missing or invalid authentication credentials — identity and authorization checks fail
- Protocol not implemented — service does not expose required UCP/AP2 endpoints, resulting in incomplete assessment
- Timeout during state transition evaluation — partial results returned
- Malformed request payload — returns validation error without assessment
