Catalog Guard API

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.

Catalog Guard API publishes 1 API on the APIs.io network: Catalog API. Tagged areas include E-Commerce, catalog-validation, Shopify, Data Quality, and csv-validation.

Catalog Guard API’s developer surface includes documentation, API reference, getting-started guide, pricing, authentication, code examples, and 17 more developer resources.

Kin Score Kin Score How this is scored →
scored 2026-09-08 · rubric v0.20.0
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/catalog-guard-api: open an issue to ask a question, or submit a pull request to add artifacts.
