How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns an inferred JSON schema object describing the structure of the input, including detected property types, required field lists, and a formal schema definition suitable for validation or documentation use.
Example use cases
Auto-generate API input schema
“I have an API that accepts user objects with fields 'userId', 'email', 'createdAt', and 'isActive' — 'userId' and 'email' are required. Can you infer a proper JSON schema definition for this?”
Validate data contract from sample
“I've got a sample JSON object with properties 'orderId', 'amount', 'currency', and 'items' — orderId and amount are required. Infer the schema so I can use it for data contract validation.”
Reverse-engineer schema from unknown payload
“I received this payload from an external API and need to understand its structure — can you infer the JSON schema from these properties: 'productId', 'title', 'price', 'inStock', where 'productId' and 'title' are required?”
Technical details
Endpoint
GEThttps://api.strale.io/x402/v2/schema-infer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to automatically derive a formal JSON schema from a known set of properties and required fields, especially in data pipeline setup, API contract generation, or validation rule creation — without manually authoring schema definitions. It pairs well with other Strale validation endpoints and returns a cryptographically auditable result.
Side effects
- Missing or malformed 'properties' input returns a 400 error
- Empty properties object yields a minimal or trivial schema
- Ambiguous type hints may produce overly broad inferred types
- Network timeout on cold start may return 504
- Unsupported property structures may not be fully represented in output schema
