How this service works
Infer schema from JSON array or CSV. Returns field types, nullability, uniqueness, completeness, min/max/mean for numeric fields. Algorithmic. SQS: 98/100.
Output
Returns per-field metadata including inferred data type, nullability (whether nulls are present), uniqueness (whether all values are distinct), completeness (percentage of non-null values), and for numeric fields: minimum, maximum, and mean values.
Example use cases
Example prompt
“Can you infer the schema for this JSON array and tell me the field types, which fields have nulls, which are unique, and the min/max/mean for any numeric columns? Here's the data: [{"id":1,"name":"Alice","score":95.5},{"id":2,"name":null,"score":82.0}]”
Technical details
Endpoint
GEThttps://api.strale.io/x402/schema-infer?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, algorithmic, serverless schema profiling of a JSON array or CSV without spinning up a database or data warehouse. Ideal for data pipeline validation, quick data audits, or pre-processing checks before loading data into a system.
Side effects
- Malformed JSON or invalid CSV returns a parse error
- Empty array or zero-row CSV may return empty schema or error
- Extremely large payloads may hit size or timeout limits
- Mixed-type columns may produce ambiguous type inference
- Missing required 'data' query parameter returns a 400 error
