How it works
Enter method-specific evidence
Replace the example values with current evidence for this workflow: Creates an origin, method, header, credential, and cache policy for browser-based API access.
Review the transparent result
The result shows its arithmetic and assumptions, then identifies the most important gap or next implementation decision.
Frequently asked questions
What does CORS Policy Builder calculate?
It converts the entered API or integration evidence into a bounded estimate, coverage measure, or decision signal for this purpose: Creates an origin, method, header, credential, and cache policy for browser-based API access.
What period and scope should I use?
Use one interface or workflow and one recent, representative period. Keep volumes, costs, consumers, tests, and evidence aligned to that same boundary.
Is the result a security or architecture approval?
No. It is transparent planning guidance based on your inputs, not a certification, guarantee, legal opinion, security review, or production approval.
When should I update the CORS Policy Builder?
Recalculate when scope, traffic, consumers, contracts, provider limits, schemas, costs, evidence, ownership, or operational requirements change materially.
