RESTful API Design Linter
RESTful API Design Linter: Audits path naming conventions: flags verb in path (`getUserData`), recommends noun resource collection `/users/42` with GET method.
About this restful api design linter
RESTful API Design Linter — browser-based utility.
How this tool works
Checks only whether each path starts with a slash, whether it contains uppercase letters, and whether five lowercase HTTP operation objects contain responses. It does not identify verbs, enforce plural nouns, or assess HTTP method semantics.
- Contract Ingestion & Format Parsing: Reads OpenAPI YAML or JSON contracts, parsing the top-level info, servers, paths, and components blocks.
- Schema Dereferencing & Graph Resolution: Resolves internal and external $ref pointers using per-path visited sets to prevent false circular recursion alarms.
- Protocol Mapping & MCP Transformation: Maps HTTP operations, path parameters, and requestBodies into MCP tool declarations with JSON Schema input schemas.
- Validation & Export: Emits valid MCP manifests or client interfaces ready for Claude, Gemini, or ChatGPT integration.
Worked example
Scenario: An API governance team audits RESTful URL paths for plural nouns and correct HTTP verb semantics.
Sample input:
Processing: Audits path naming conventions: flags verb in path (`getUserData`), recommends noun resource collection `/users/42` with GET method.
Illustrative output:
Limits and verification
Requires specifications to contain required OpenAPI root keys ('openapi', 'info', 'paths'). Handles deep schema recursion by truncating self-referential children with a safe guard marker. Flags invalid YAML indentation with line numbers.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
What does REST API Design Linter examine?+
It reads paths from the supplied document, flags paths without a leading slash or with uppercase letters, and requires responses on recognized REST methods.
What did the browser fixture check?+
A GET operation under Pets with no responses produced three issues: missing slash, lowercase-kebab-case preference, and required responses.
Does a valid result guarantee a complete API design?+
No. The local checks are limited to these naming and response-presence rules; authentication, schemas, versioning, caching, status semantics, and deployment behavior are not assessed.
Which methods receive the responses check?+
The implementation checks get, post, put, patch, and delete entries. Other keys under a path are not treated as these REST operations.
