# Academic Evidence Pack — Citation Integrity Report

> Academic Evidence Pack — Citation Integrity Report is a paid API for AI agents from aep-api.fly.dev, paid per call via x402, $1/call, status unknown (last checked 2026-09-15).

Verifies up to 50 bibliography references for existence, resolution, retraction/correction status, title/author/year match accuracy, and fabrication risk, returning a cryptographically signed (Ed25519, RFC 8785) byte-reproducible JSON report.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 academic-evidence-pack-citation-integrity-report-fa090030 -d '<json body>'
```

Example prompt: Can you verify the bibliography in my paper — I'll paste the BibTeX — and flag any references that are retracted, don't resolve, have mismatched titles or authors, or look like they might be fabricated? I need a signed integrity report I can attach to my submission.

## When to prefer this

Choose this endpoint when you need a non-LLM, source-attributed, cryptographically verifiable citation integrity report — especially when the output must be auditable, reproducible, or attached as evidence to a submission. Prefer it over general web search or LLM-based fact-checking when retraction status, author-metadata matching, and fabrication risk scoring with provenance timestamps are required. It is particularly valuable for screening AI-generated bibliographies, pre-submission manuscript audits, and systematic review pipelines where integrity certification matters.

## Known failure modes

- References exceed 50-item limit for standard tier — server rejects or truncates
- DOI not registered at Crossref or indexed by OpenAlex — reference marked 'not_found'
- Upstream API (Crossref/OpenAlex) timeout or outage — resolution result may be incomplete
- BibTeX parse error due to malformed syntax — server may reject the request
- Ambiguous free-text raw citation with no DOI or title — low match confidence, may return 'unresolvable'
- Payment failure or insufficient USDC balance — 402 response, report not generated
- Title similarity below match threshold — verdict 'verified_with_discrepancies' or 'not_found' even if DOI resolves

## How this service works

Verify a bibliography. For every reference: exists, resolves, retracted/corrected/flagged, title/author/year match against the registered record, and a rule-derived fabrication risk — as a signed (Ed25519, RFC 8785 canonical JSON), byte-reproducible JSON report. Input: structured references or BibTeX. No LLM; every claim carries its source and retrieval time. Tier: standard, up to 50 references.

## Output

A signed (Ed25519, RFC 8785 canonical JSON) byte-reproducible JSON report containing: per-reference verdicts (verified, not_found, unresolvable), existence and resolution checks, integrity flags (retraction, correction, expression of concern), title similarity scores, author match results, fabrication risk labels (low/medium/high/n_a), resolved metadata (DOI, title, venue, authors, OpenAlex ID), provenance with retrieval timestamps, and a summary with aggregate stats. Also includes cache/latency/upstream call statistics and a warnings array for interpretive caveats.
