How this service works
Change audit: prek: Audit JSON changes and validate before/after for prek. Uses a pinned SchemaStore definition on this PC. Reports JSON pointers and rule violations, added/removed/changed paths and introduced/resolved errors. Up to 100 KB per document; no YAML/TOML parsing or deployment/security guarantee. 0.01 USDC includes one two-document change audit.
Output
Returns a structured report listing JSON pointers for all added, removed, and changed paths between the before and after documents, along with newly introduced schema rule violations and any previously existing errors that were resolved, based on the pinned SchemaStore prek definition.
Example use cases
Pre-K config update validation
“I just updated our prek JSON configuration and want to make sure I didn't break anything — can you compare the old version and new version and list any schema violations that were introduced or fixed, plus all the fields that changed?”
Reviewing a prek JSON migration
“We migrated our prek data file to a new format. Can you run a change audit between the original JSON and the migrated JSON to show me every added, removed, or changed path, and flag any new rule violations against the prek schema?”
Debugging a prek schema regression
“Something broke in our prek JSON after the last edit. Can you compare the last known good version against the current one and show me exactly which JSON pointers changed and which schema errors appeared that weren't there before?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-schema-prek-299e90de-changes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to audit schema-level changes to a prek-typed JSON document specifically, want to see both structural diffs (added/removed/changed paths) and validation diffs (introduced/resolved errors) in one call, and need a pinned SchemaStore definition rather than a user-supplied schema. Not suitable for YAML/TOML documents, files over 100 KB, or schemas other than prek.
Side effects
- Document exceeds 100 KB limit — request rejected
- Nesting depth exceeds 32 levels — parsing error
- Input is not valid JSON (e.g. YAML or TOML) — not supported, returns error
- Malformed request body — missing before or after fields
- Network or payment processing failure — no audit result returned
