OKF vs OpenAPI
Compare contracts and context.
Open pageAPI guide
OpenAPI to OKF conversion guide
OpenAPI to OKF is a workflow for keeping OpenAPI as the API contract while moving reviewed endpoint context, owner notes, examples, limits, and support notes into OKF files.
Short answer
Do not replace OpenAPI with OKF. Convert endpoint context, not the contract itself.
What OpenAPI to OKF means
OpenAPI paths, methods, parameters, schemas, responses, and authentication patterns stay in OpenAPI. OKF carries the surrounding context: owners, examples, limits, support notes, review warnings, and related docs.
What OKF adds
OKF adds owner notes, support context, examples, limits, review warnings, and related documentation around an API contract. It should point back to OpenAPI instead of copying schema details blindly.
Before you convert
- Start with the current OpenAPI specification or API reference URL.
- Collect reviewed examples, error-handling notes, and support ownership details.
- Remove tokens, private request bodies, customer identifiers, and restricted operational notes.
- Choose one stable API area before expanding the bundle.
- Keep schema and contract changes in OpenAPI, then review the surrounding context in OKF.

Use a small, consistent tag set.

# Links
- Validator: https://openknowledgeformat.online/okf-validator/
- Examples: https://openknowledgeformat.online/okf-examples/Convert one API area first
- Pick one stable endpoint or API area.
- Link the OpenAPI file or API reference as the resource.
- Write the endpoint purpose in normal language.
- Add examples, limits, warnings, owner notes, and related docs.
- Validate the file with the OKF Validator.
- Validate the API bundle with the OKF Folder Validator.
What must stay in OpenAPI
- Do not claim OKF validates OpenAPI schemas.
- Do not generate client code from OKF.
- Do not let OKF contradict the OpenAPI contract.
- Do not mechanically convert every endpoint into a separate thin concept file.
- Do not include tokens, private request bodies, or customer data in examples.
Review boundaries
Generated API context remains pending until an owner reviews the contract link, examples, limits, and support notes. OKF does not validate OpenAPI schemas or replace contract tooling.

FAQ
Common questions
Can OKF replace OpenAPI?
No. OpenAPI remains the API contract. OKF adds context around that contract.
Can I generate OKF drafts from OpenAPI?
Yes, but owner notes, warnings, examples, and support rules still need human review.
Does OKF validate schemas?
No. Use OpenAPI tooling for schema and contract validation.
What should never move into OKF?
Do not move tokens, private request bodies, customer data, or exact schemas that must stay controlled by the OpenAPI contract.
