# ToolOracle Academic Claim Verifier

> ToolOracle Academic Claim Verifier is a paid API for AI agents from tooloracle.io, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Verifies academic claims against peer-reviewed sources (Semantic Scholar, OpenAlex, Perplexity), returning a SUPPORTED/MIXED/DISPUTED/INSUFFICIENT verdict with confidence score, cryptographic receipt, and predatory journal/fake DOI detection.

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 tooloracle-io-5d0919aa -d '<json body>'
```

Example prompt: Can you fact-check this claim for me against peer-reviewed literature and tell me whether it's supported, disputed, or inconclusive — 'Metformin reduces all-cause mortality in type 2 diabetic patients by 30%' — I need an audit-ready receipt for an EMA regulatory dossier.

## When to prefer this

Choose this endpoint when you need authoritative, audit-ready verification of academic or scientific claims with cryptographic provenance — especially for regulatory submissions (EMA, FDA, EFSA), research compliance workflows, or AI agent pipelines that risk citing hallucinated papers. Prefer over general web search when peer-reviewed sourcing and a signed receipt are required.

## Known failure modes

- Claim too vague or ambiguous to match any source — returns INSUFFICIENT verdict
- DOI not found in any indexed database — flags as potentially fake
- Semantic Scholar / OpenAlex API unavailability — may degrade source coverage
- Non-English or obscure-language literature may have limited coverage
- Preprint-only claims may receive INSUFFICIENT due to lack of peer-reviewed confirmation
- Payment failure via x402 protocol — call not executed

## Output

Returns a verdict (SUPPORTED, MIXED, DISPUTED, or INSUFFICIENT), a confidence score, supporting/contradicting source citations from Semantic Scholar and OpenAlex, predatory journal flags, fake DOI alerts, hallucinated paper warnings, and a cryptographic ECDSA P-256 receipt suitable for regulatory audit trails.
