# Publication Bundle Consistency Checker

> Publication Bundle Consistency Checker is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.022002/call, status unknown (last checked 2026-10-15).

Validates consistency across 2–8 declared views of a publication (article, registry, API) against canonical URL, content, release, and source-set digests, flagging stale, withdrawn, or substituted views.

## 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 publication-bundle-consistency-checker-f77609e4 -d '<json body>'
```

Example prompt: Before we push this release, can you check the bundle consistency for our publication at https://example.com/articles/2024/q4-report — compare these 3 views (article, registry, API) against the content digest sha256:abc123, release digest sha256:def456, and source-set digest sha256:ghi789 using public data class, and flag anything stale, withdrawn, or substituted?

## When to prefer this

Use this endpoint when you need a lightweight, offline-style pre-release check that compares declared publication views against known digests without triggering live fetches or promoting releases. Ideal for CI/CD pipelines, editorial release gates, or audit trails where you need to confirm all views of a publication bundle are synchronized before going live. Prefer this over live-fetch validators when you already hold canonical digests and want deterministic, side-effect-free consistency verification.

## Known failure modes

- Fewer than 1 or more than 8 views provided — validation error
- Invalid or malformed digest strings exceeding 71 characters — schema rejection
- Canonical URL missing or exceeding 512 characters — request rejected
- Unsupported dataClass value outside 'public' or 'synthetic' — enum validation failure
- Downstream timeout if bundle processing exceeds service limits — 5xx response
- Stale retained result not found after 24-hour window — result expiry error

## How this service works

Check declared publication views before release. Compare 2-8 article, registry and API views against canonical URL, content, release and source-set digests; flag stale, withdrawn or substituted views. No live fetch, release promotion or semantic content verification. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

## Output

Returns a consistency report for the submitted publication view bundle, indicating which views are consistent, stale, withdrawn, or substituted relative to the supplied canonical URL and digests. Includes a retained result recoverable for 24 hours and minimal receipt metadata retained for 90 days. Does not perform live fetching, release promotion, or semantic content verification.
