How it works
Enter method-specific evidence

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 API Build-vs-Buy Evaluator calculate?
It converts the entered API or integration evidence into a bounded estimate, coverage measure, or decision signal for this purpose: Compares building an integration with using a vendor, marketplace app, middleware, or embedded platform.
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 API Build-vs-Buy Evaluator?
Recalculate when scope, traffic, consumers, contracts, provider limits, schemas, costs, evidence, ownership, or operational requirements change materially.
