Example prompt: Can you validate this Backstage app-config JSON against the Spotify Backstage schema and tell me which fields are invalid or missing? Here's my config: {"app":{"title":"My Portal","baseUrl":"http://localhost:3000"}}

## When to prefer this

Choose this endpoint when you need to validate a Spotify Backstage app-config JSON document against the official SchemaStore schema definition before deployment, during CI/CD pipelines, or while debugging configuration errors. It is particularly useful for platform engineers or DevOps teams who want automated, per-document schema checks with specific JSON pointer error reporting. Prefer this over generic JSON schema validators when you specifically target the Backstage app-config format with a pinned, stable schema version.

## Known failure modes

- Document exceeds 100 KB limit — request rejected
- JSON nesting depth exceeds 32 levels — request rejected
- Malformed JSON submitted (not parseable) — validation cannot proceed
- Schema pointer violations returned when required fields are absent or wrong types
- YAML or TOML formats not supported — only raw JSON accepted
- Network or service errors may return 4xx/5xx HTTP codes
