Validate inbound records before they break downstream workflows

Use deterministic validators between ingestion and storage. Check input JSON against supported contract rules, screen batches for invalid or duplicate records, and find exact field changes before an automated downstream action.

What you can automate

Gate a scheduled ETL import before writing invalid customer records.
Verify LLM-generated JSON against an explicit supported schema subset.
Inspect schema changes during deployment and identify affected keys.

Limitations

JSON Contract Check supports a documented subset of JSON Schema, not all keywords.
Data Quality Gate accepts bounded batches of up to 200 records.
This is validation, not a guarantee that source data is factually correct.

Common integration questions

Can a scheduled application pay per result?

Yes, with an approved payment method and the documented per-call credits or x402 pricing. No schedule or payment is auto-enabled.

Is the API key embedded in templates?

No. Store credentials privately in your workflow tool and use an Idempotency-Key for safe retries.

Try before you integrate

Published input samples, current product prices and system health are publicly accessible. Executing your own data requires an authorized payment; we do not publish paid results as free samples.
