How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with a 'fields' map where each key is a field name and the value contains observed types (with counts) and nullability; also includes a schema version identifier, an advisory note that the inference is descriptive not prescriptive, and the total record count analyzed.
Example use cases
Unknown API response profiling
“I'm getting back JSON from a third-party API and I don't have their docs — can you analyze these 10 sample records and tell me the field names, their types, and which ones might be null?”
ETL pipeline schema bootstrapping
“Before I set up my data pipeline, I need to know the schema of this batch of raw records. Can you infer the field types and nullability from these samples so I know how to configure my destination table?”
Data quality audit before ingestion
“I have a sample of customer records from a CSV export and I want to understand what types each column actually contains before importing it into our database — can you infer the schema from these records?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/schema-inference?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need lightweight, instant schema detection from a sample of JSON records without setting up a full data catalog or schema registry. It is ideal for agents handling unknown or undocumented data sources, bootstrapping ETL pipelines, or quickly profiling a dataset before processing. Prefer it over manual inspection or heavier data-profiling tools when you need a pay-per-call, no-signup solution with verifiable delivery via x402.
Side effects
- Empty records array returns no field info
- Highly heterogeneous or deeply nested records may produce ambiguous type counts
- Payment failure via x402 results in 402 response before inference runs
- Malformed JSON input returns a 400-level error
- Very large record arrays may time out or be truncated
