# Observed JSON sample shapes

Build-time release reference. Runtime readiness, deployment, payment settlement and external indexing are not evaluated here. Prices are proposed; this file cannot authorize execution or payment.

Build an optional, open observational JSON Schema draft and counted evidence from supplied JSON samples; never infer a real API contract.

Release: 0.29.0. Built: 2026-10-06T15:38:00Z.

## Choose for
- Review a recursive open schema draft inferred from bounded supplied examples
- Inspect sample counts, optional properties and unobserved empty-array items

## Outside this profile
- Establishing a universal API contract or production rejection policy
- Inferring required fields, enums, formats, ranges, cross-field correlations or compatibility
- Generating a tool definition or assuming generalized fixture-generator compatibility
- Network access, filesystem changes, target execution, publishing or deployment

Proposed nominal USD 0.004 per successful call; payer fees excluded. No verified runtime availability.
