## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sky-observations-reference-integrity-map-cbdeaac9 -d '<json body>'
```

Example prompt: Check these 10 synthetic sky observation records for broken parent links and ownership cycles — flag any rows where the owner or subject reference doesn't resolve or creates a circular dependency.

## When to prefer this

Choose this endpoint when you need to validate reference integrity (parent existence and cycle detection) specifically within sky observation records segmented by owner and subject fields. It is best used as a pre-ingestion or audit step for batches of up to 32 public or synthetic celestial observation records where nonpersonal metadata handling is required. It is not a substitute for independent data certification.

## Known failure modes

- Exceeds 32 row limit — request rejected
- nonpersonalMetadata not set to true — validation error
- dataClass not one of 'public' or 'synthetic' — enum validation failure
- Empty rows array — minimum 1 item required
- Malformed row objects — schema validation error
- Service unavailable — 402/503 response

## How this service works

Check parent existence and cycles within owner and subject Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a reference integrity map indicating for each supplied row whether parent records exist and whether any cycles are present in the owner or subject relationship graph. This is a supplied-record analysis only, not independent certification.
