## 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`):

Example prompt: Can you convert the Amazon ASIN B08N5WRWNW to its EAN-13 and UPC barcodes for the US marketplace?

## When to prefer this

Choose this endpoint when you have an Amazon ASIN and need to obtain standardized retail product identifiers (EAN-13, UPC, ISBN) for cross-platform listing, inventory management, barcode printing, or product matching in non-Amazon systems. It is ideal for e-commerce sellers, catalog enrichment pipelines, and book/product resellers who need to reconcile Amazon product IDs with global standards.

## Known failure modes

- Invalid or non-existent ASIN returns empty results array or error status
- ASIN from a different marketplace may return no identifiers if country mismatch
- Product may not have all identifier types (e.g. a book may have ISBN but not UPC)
- Rate limiting or payment failure may result in 402 or 429 responses
- Non-physical products (digital downloads, services) may have no GTIN/EAN/UPC

## How this service works

Convert an Amazon ASIN to GTIN / EAN / UPS identifiers. Valid values for type are EAN-13, UPC, or ISBN.

## Output

Returns an object containing the original ASIN, a status field, a unique request ID, and an array of identifier results. Each result item includes the identifier type (EAN-13, UPC, or ISBN) and its corresponding value (the actual barcode/code string).
