Look up unified sneaker/streetwear product data by GTIN barcode via paid API.
What it does
KicksDB's GTIN endpoint lets callers retrieve unified product information for sneakers and streetwear by submitting a GTIN (Global Trade Item Number) barcode. The service aggregates market data — including prices, sales history, and availability — from major resale platforms such as StockX, GOAT, and others, returning a consolidated view per product.
The endpoint is served over the MPP (Micropayment Protocol) using the Tempo settlement method on chain ID 4217. Each request is a one-shot charge of 500 base units of pathUSD (6 decimals), which works out to $0.0005 per lookup. The provider covers gas fees (feePayer: true), so callers only pay the data fee. Authentication is handled entirely through the MPP 402 challenge/response flow — no API keys are needed.
Documentation beyond the endpoint description is not currently published; the provider's root domain and common doc paths all return 404. The request format is a GET to `/v3/unified/gtin`, presumably with the GTIN value passed as a query parameter (e.g., `?gtin=<barcode>`). Response schema details are not available from the probe or crawl, so the exact fields returned must be discovered by making a paid call.

- —Developers building sneaker/streetwear resale tools
- —AI agents that need real-time market pricing per barcode scan
- —Applications requiring unified product data across multiple resale platforms
Not for

Quality
The endpoint is live and returns a valid MPP 402 challenge with clear pricing and settlement details. However, there is no published documentation, no OpenAPI schema, no example responses, and no crawlable content — all doc paths return 404. The request parameter format and response schema must be inferred or discovered empirically.
Warnings
- —No documentation found — root domain and /docs, /api, /pricing, /README all return 404.
- —Response schema is unknown; exact fields returned are not documented.
- —Request parameter format (query param name for GTIN) is inferred, not confirmed.
- —Currency address 0x20c0…8b50 assumed to be pathUSD with 6 decimals on chain 4217; if different, the stated price ($0.0005) would be incorrect.
