How this service works
JSON Schema validation — validate JSON records, invoices and payloads against the bounded Draft 2020-12 Atlas profile; return valid status and deterministic JSON Pointer errors. This validator subset supports exact numbers and local references with Go RE2 patterns; unsupported schemas are rejected and remote schemas are never loaded.
Output
Returns a valid/invalid status flag and, when invalid, a deterministic list of JSON Pointer paths indicating exactly which parts of the document failed validation, along with error descriptions. No remote schemas are loaded; unsupported schema keywords are explicitly rejected.
Example use cases
Invoice payload pre-submission check
“Before I submit this invoice JSON to the billing system, validate it against our Draft 2020-12 schema and list any JSON Pointer errors so I can fix them first.”
API request body conformance check
“I'm getting errors from the downstream API — can you validate this JSON request body against the provided schema and tell me which fields are failing and where exactly?”
Data import record validation
“We're importing a batch of product records and I need to know if this sample JSON record passes our schema — can you validate it and give me the exact error locations if it doesn't?”
Technical details
Endpoint
POSThttps://data-tools.use.x402atlas.com/json-schema-validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need strict, deterministic JSON Schema validation against the bounded Draft 2020-12 Atlas profile with exact number support, Go RE2 pattern matching, and JSON Pointer error reporting. Ideal for invoice validation, API payload checking, and data import verification where reproducible results and no remote schema loading are required. Prefer this over general-purpose validators when your environment requires predictable, sandboxed validation without network calls.
Side effects
- Schema uses unsupported keywords outside the Atlas profile subset — request is rejected with an explanation
- Remote $ref or external schema URIs are referenced — these are never fetched and validation fails
- Input JSON is malformed or unparseable — returns parse error before validation
- RE2-incompatible regex patterns in the schema — rejected as unsupported
- Missing required schema or document fields in the request body — returns 400-style error
