API Response Matrix Mock Builder
Selects one HTTP status from a supplied response map and returns its mock body; defaults to a small 200/404 map.
About this api response matrix mock builder
Selects one HTTP status from a supplied response map and returns its mock body; defaults to a small 200/404 map Validates and converts interface schemas client-side without transmitting private endpoint specifications.
API contract & interface schema logic
Reads responses and optional status, validates the status range, and returns one selected status/body pair.
Worked schema conversion scenario
Scenario: A QA tester selects one status and body from a local response map.
Sample input:
Processing: Select status 200 from the supplied response map and return only its body.
Illustrative output:
Schema version & syntax constraints
The built-in map has 200 and 404 only. It does not generate a full matrix, call an API or validate response schemas.
API specifications and schema models in API Response Matrix Mock Builder reflect OpenAPI and JSON Schema standards. Verify generated schemas against your runtime validator.
Client-side schema processing boundary
Schema analysis and protocol mapping in API Response Matrix Mock Builder execute locally in the browser tab without uploading endpoint definitions.
OpenAPI Specification & JSON Schema standards

Operating System & Terminal CLI Interoperability Protocols
For systems engineers, DevOps practitioners, and backend developers integrating this workflow into automated Continuous Integration (CI/CD) pipelines, crontabs, or shell environments, the client-side algorithms executed by API Response Matrix Mock Builder map directly to native operating-system toolchains:
- Linux & macOS POSIX Terminal Environments: Mirror REST and OpenAPI workflows using `curl -sSL -X POST -H 'Content-Type: application/json' -d @payload.json https://api.endpoint/v1` or `httpie POST https://api.endpoint/v1 < payload.json`. For OpenAPI contract validation, leverage `npx @stoplight/spectral-cli lint openapi.yaml` or `oasdiff -base original.yaml -revision update.yaml` to detect breaking schema mutations in git pre-commit hooks.
- Windows 11 / 10 PowerShell 7+ & Command Environments: In Windows PowerShell 7+, dispatch API requests using `Invoke-RestMethod -Uri 'https://api.endpoint/v1' -Method Post -Body $payload -ContentType 'application/json'`. Enforce modern TLS 1.3 or TLS 1.2 handshakes via `[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 -bor [Net.SecurityProtocolType]::Tls13` to avoid handshake negotiation timeouts on legacy hosts.
- Browser Runtime Sandboxing & Resource Allocation: OpenAPI-to-MCP generation and schema graph traversals execute synchronously within a client-side WebAssembly / TypeScript abstract syntax tree compiler. Cyclic references are detected through a path-indexed recursion stack, preventing stack overflow while preserving complete shared object definitions without remote schema resolution network requests.
Diagnostic Failure Modes & Edge-Case Recovery
When unexpected inputs or boundary conditions occur during data processing, consult this structured diagnostic recovery matrix:
| Fault Condition | Observed Symptom | Engineering Remediation Procedure |
|---|---|---|
| Missing required OpenAPI path operation object | Schema validation error: paths./endpoint lacks get/post definition | Provide at least one valid HTTP method (get, post, put, delete) and an associated responses object for each path item. |
| Cyclic $ref pointer reference in schema | Recursion guard triggered badge displayed | CZOA automatically terminates recursive branches while expanding legitimate shared models. Verify that recursion terminates with an optional property. |
| Invalid JSON Schema draft version declaration | Unknown schema dialect warning | Specify $schema as http://json-schema.org/draft-07/schema# or https://json-schema.org/draft/2020-12/schema. |
| Missing Bearer token or authorization header | HTTP 401 Unauthorized simulation response | Inspect the securitySchemes block in your OpenAPI document and provide a valid Authorization: Bearer <token> test credential. |

How to use it
- Paste JSON with responses map and optional status.
- Select one status, defaulting to the first map key, and return its body.
- Read the selected status/body JSON.
Frequently asked questions
What does API Response Matrix Mock return?+
It parses a responses object, chooses the supplied status or first key, requires a three-digit numeric HTTP status from 100 through 599, and returns that numeric status with its body or a no-mock error body.
Can you show an input and its result?+
Status 404 with a matrix body error missing returned numeric status 404 and exactly that error body.
Which HTTP response behavior is absent?+
It does not create a server response, validate status semantics, headers, content type, schemas, serialization, caching, redirects, network errors or asynchronous behavior.
Does a mock prove an API contract?+
No. It selects local JSON only; real endpoints, client behavior, authentication, error handling and contract tests must be checked separately.
