# Catalog Guard API

**Canonical:** https://apis.io/providers/catalog-guard-api/  
**APIs profiled:** 1

A bounded, fail-closed catalog preflight and validation service for Shopify-shaped supplier product CSVs. Exposes an unauthenticated JSON HTTP API that validates raw CSV text or normalized product rows and returns a deterministic result: safe rows, blockers and warnings, each finding carrying a row index, field, stable code and message. Ambiguous input is refused rather than guessed — unclosed quotes, malformed rows, duplicate headers, duplicate normalized SKUs and incomplete variant pairs all become blockers, and supplier categories are treated as audit-only rather than mapped to a Shopify taxonomy. The service does not accept file uploads, credentials, payment data or store connections, holds no storage, and never imports or modifies a catalog; every successful response repeats those disclosures inline as machine-readable fields. Access is controlled by input bounds and a best-effort rate limit rather than by identity. Commercially it is fronted by a free in-browser CSV preflight, a $149 bounded human CSV Diagnostic, and a separate free Shopify store-launch referral path.
