How this service works
JSON Schema validation with JSON Pointer errors: Validates a JSON document against a JSON Schema (draft-07, 2019-09 or 2020-12, formats included) and returns valid true/false with every error as a JSON Pointer, keyword and message. Input: json and schema (POST for large documents). Limits: 1 MB JSON
Output
A JSON object containing: a boolean `valid` field indicating overall pass/fail; an `errors` array where each entry has a `pointer` (JSON Pointer string to the failing location), `keyword` (the schema keyword that failed, e.g. 'required', 'type', 'minLength'), and `message` (human-readable description); an `error_count` integer; and the `draft` of the JSON Schema detected. Returns `valid: true` with an empty errors array when the document passes.
Example use cases
CI pipeline config validation
“I have a GitHub Actions workflow config as JSON and a strict schema I wrote — can you run it through schema validation and list every error with its exact JSON Pointer so I can fix them before merging?”
API request body compliance check
“Before I send this POST body to our payment API, can you validate it against the OpenAPI request schema and tell me which properties are missing or have the wrong type?”
User-submitted form data validation
“A user just submitted this form data as JSON and I need to check it against our registration schema — please validate it and return all the errors with their field paths so I can show the right error messages.”
Technical details
Endpoint
GEThttps://shop.lordevo.com/api/quick/json-validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need precise, per-field validation errors expressed as JSON Pointers rather than just a pass/fail result. It is ideal for developer tooling, CI pipelines, API request validation, and form validation workflows where you need to map errors back to specific document locations. It supports all three modern JSON Schema drafts including format validation, making it more complete than minimal validators. Prefer it over generic linters when you need structured, machine-readable error details compatible with all three major JSON Schema drafts.
Side effects
- JSON document exceeds 1 MB limit — request rejected
- Schema exceeds 200 KB limit — request rejected
- Malformed JSON in `json` or `schema` params — parse error returned
- Unsupported schema draft (not draft-07, 2019-09, or 2020-12) — may return error or unexpected results
- Missing required query parameters `json` or `schema` — bad request response
- Network timeout for very complex schemas with large documents
