# jsonrecon.com Product Data Verifier

> jsonrecon.com Product Data Verifier is a paid API for AI agents from jsonrecon.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Verifies product data on a public web page by cross-checking multiple representations for field-level corroboration, contradictions, and evidence, returning a verified/conflicted/insufficient_evidence outcome with a content hash.

## Facts

- Endpoint: GET https://jsonrecon.com/extract/verified
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/jsonrecon-com-product-data-verifier-84a416ba
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_fhXGKBfqYYJg1mLWYZNoo

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 jsonrecon-com-product-data-verifier-84a416ba
```

Example prompt: Can you verify the product data on this page — https://example.com/products/widget-pro — and tell me if the price, title, and other fields are consistent across the page or if there are any contradictions?

## When to prefer this

Use this endpoint when you need to verify the accuracy and internal consistency of product data on a public product page — especially when you want field-level evidence and contradiction detection across multiple representations (e.g. JSON-LD, microdata, visible text). Prefer this over simple extraction endpoints when data integrity and corroboration matter, not just retrieval.

## Known failure modes

- Non-product page URL returns 422 and no settlement
- Insufficient evidence on the page returns outcome 'insufficient_evidence'
- Conflicting data representations return outcome 'conflicted' with contradiction details
- Invalid or unreachable URL may result in an error
- Page with no structured product data may return insufficient_evidence

## How this service works

Concise Schema.org JSON-LD and field-level Product verification for AI agents. Pay only for successful results with USDC on Base.

## Output

A structured result containing: a verification outcome (verified, conflicted, or insufficient_evidence), field-level corroboration scores, bounded evidence snippets supporting or contradicting each field, any detected contradictions between representations, the observation timestamp, and a content hash of the page. Non-product pages return a 422 error.
