## 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 reading-plans-reference-integrity-map-4e114153 -d '<json body>'
```

Example prompt: Check the reference integrity of this reading plan — I have an array of up to 32 plan entries and their associated units, all public data with no personal metadata, and I need to know if any unit references are inconsistent with the declared edition and section manifests.

## When to prefer this

Choose this endpoint when you need to validate reading-plan unit references purely against declared edition and section manifests using offline typed metadata — no book text, licensing, availability checks, or manuscript lookups are performed. Ideal for pre-publish audits, import validation, or debugging structural reference issues in reading plans without requiring access to live content.

## Known failure modes

- Plan array exceeds 32 items — request rejected
- Units array exceeds 32 items — request rejected
- nonpersonalMetadata not set to true — request rejected
- Invalid dataClass value (must be 'public' or 'synthetic') — validation error
- Malformed plan or unit entries — schema validation failure
- Payment not provided or insufficient — 402 payment required
- Result expired after 24-hour retention window — receipt metadata only available

## How this service works

Verify supplied reading-plan unit references against declared edition/section manifests. No book text, licensing grant, availability check or manuscript lookup. Offline typed metadata only. Retained-result recovery: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns a reference integrity map indicating which unit references in the supplied reading plan match or conflict with the declared edition and section manifests, along with details on any mismatches or integrity violations found. Results are retained for 24 hours; minimal receipt metadata is kept for 90 days.
