# Publication Bundle Consistency Checker

> Publication Bundle Consistency Checker is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.022/call, status unknown (last checked 2026-09-14).

Validates consistency across 2-8 declared publication views (article, registry, API) by comparing them against canonical URL, content, release, and source-set digests — flagging stale, withdrawn, or substituted views without live fetching.

## 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-053b8802 -d '<json body>'
```

Example prompt: Before we release this article, check that all 4 declared publication views are consistent — the canonical URL is https://example.com/articles/2024/my-story, content digest is sha256-abc123, release digest is sha256-def456, source-set digest is sha256-ghi789, and the data class is public. Flag anything stale or substituted.

## When to prefer this

Choose this endpoint when you need a deterministic, offline consistency check across multiple declared publication views before release — without performing live fetches or semantic content analysis. It is ideal for CI/CD pipelines, pre-release audits, and evidence-chain validation where you hold the digests locally and need to confirm no view has gone stale, been withdrawn, or been silently substituted. Prefer this over live-fetch validators when immutability and auditability of the check itself (via receiptDigest) are required.

## Known failure modes

- Invalid or malformed digest strings (exceeds 71 chars or wrong format) cause validation rejection
- Fewer than 1 or more than 8 views in the array triggers schema validation failure
- Missing required fields (canonicalUrl, contentDigest, releaseDigest, sourceSetDigest) cause request rejection
- Unsupported dataClass value (outside 'public' or 'synthetic') returns enum validation error
- Payment failure or insufficient USDC balance prevents execution
- Malformed canonicalUrl (empty or exceeding 512 chars) causes input rejection

## 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Compare 2-8 article, registry and API views against canonical URL, content, release and source-set digests; flag stale, withdrawn or substituted views.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.

## Output

Returns a structured result object indicating whether the declared publication views are consistent with the provided canonical URL, content, release, and source-set digests. Includes a list of boundary violations (up to 128), an input digest, a receipt digest, the offer ID, and version metadata. Flags specific views as stale, withdrawn, or substituted where discrepancies are detected.
