Generate a JSON schema API

Build a schema from supplied examples. Required properties are keys present on every example. Whole numbers are integer. Additional properties stay allowed.

The Generate a JSON schema operation is part of the API Integration Intelligence API on BRAINIAC.software. Build a schema from supplied examples. Required properties are keys present on every example. Whole numbers are integer. Additional properties stay allowed. It is exposed as POST /api/v1/integration/json-schema-generate and priced at $0.04 USDC on Base. Payment uses the x402 exact scheme: an unpaid call returns HTTP 402 with payment requirements; after paying the exact USDC amount, retry the same request with a payment-signature header and Idempotency-Key. No account and no API key are required. Data sources for this product: Schemas, examples, and payloads supplied in the request. Limitations: No external API is called and no user-supplied code is executed. Validation covers a documented JSON Schema subset. It is not a full draft certification. Mappings are proposed only for paths or field names that exist on both sides. A breaking change is labeled only when the caller sets side to request or response. Transforms are limited to rename, copy, pick, omit, cast, and default. Outputs are compliance prechecks, drafts, or data lookups for human review. They are not official determinations, legal advice, identity confirmation, or certified filings. Related operations in this group include Validate a payload, Normalize an API response, Transform a payload, Generate a field map.
