OpenAPI specification for NEM Infrastructure Server (NIS) REST API. The API is implemented in the nis module in this repository.

Canonical API documentation: https://nemproject.github.io/ — use it for endpoint descriptions and verification.

• Node.js 20 LTS or higher

YAML style and syntax for files under spec/ are checked by the monorepo Linters job (linters/scripts/lint_yaml.sh -> yamllint with linters/yaml/.yamllint). Run that from the repository root if you need the same check locally:

./linters/scripts/lint_yaml.sh

1. Clone the monorepo and enter this package.

git clone https://github.com/NemProject/nem.git
cd nem/openapi

2. Install dependencies.

npm install

Compile the specification. The generated output is saved under the _build directory.

npm run build

Checks links in the built specification (_build/openapi3.yml).

npm run test

In CI the flow is split into dedicated stages:

• scripts/ci/lint.sh -> npm run lint (OpenAPI lint on spec/openapi.yml)
• scripts/ci/build.sh -> npm run build (bundle to _build/openapi3.yml)
• scripts/ci/test.sh -> npm run test

Generate a Postman collection from the built specification.

npm run postman

Release in monorepo is component-scoped (openapi/) and produces versioned OpenAPI + Postman artifacts.

1. Bump version in package.json and update CHANGELOG.md.
2. Run publish script:

scripts/ci/publish.sh

This prepares:

• _build/openapi3.yml
• _build/openapi3.json
• _build/postman.json
• _build/v<version>/openapi3.yml
• _build/v<version>/openapi3.json
• _build/v<version>/postman.json

Optional: create a GitHub release with assets (requires authenticated gh CLI):

OPENAPI_RELEASE_CREATE_GH=1 OPENAPI_RELEASE_TAG=openapi/v<version> scripts/ci/publish.sh
