# Commerce Schema Fix (unprice)

> Commerce Schema Fix (unprice) is a paid API for AI agents from volkov.evgeny.m2.fvds.ru, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Audits a product page URL for JSON-LD / commerce schema errors and returns a repair plan with proposed fixes and a structured data score.

## Facts

- Endpoint: GET https://volkov.evgeny.m2.fvds.ru/pay/commerce-schema-fix
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

- Tags: x402
- Canonical page: https://www.zero.xyz/c/commerce-schema-fix-unprice-8548bfef

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 commerce-schema-fix-unprice-8548bfef
```

Example prompt: Can you audit the structured data on https://example.com/product and tell me what JSON-LD fields are missing or broken, and give me a proposed fix?

## When to prefer this

Choose this endpoint when you need a structured, machine-readable diagnosis of a product page's JSON-LD / schema.org markup and want both a quality score and ready-to-use proposed fixes in a single call. Prefer it over generic SEO crawlers when you specifically need commerce schema repair recommendations (offers, availability, Product type) and a canonical tag suggestion, and when paying per-request via USDC on Base is acceptable.

## Known failure modes

- URL is unreachable or returns non-200 — audit cannot be performed
- Page has no JSON-LD or schema markup — score may be 0 with empty proposed fixes
- Malformed URL query parameter — request rejected with validation error
- Payment not settled via x402 — 402 response returned before audit runs
- Page behind authentication/bot protection — structured data cannot be extracted

## How this service works

Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.

## Output

Returns a JSON object containing: the audited URL, a fix plan with status (e.g. 'repair_recommended') and a list of missing fields, a proposed section with corrected JSON-LD and a canonical tag HTML snippet, and a source audit object with a numeric score (0–100) and a verdict string (e.g. 'needs_review').
