Technical details
Endpoint
POSThttps://stableproduct.dev/api/channel3/similarWhen to prefer
Use this endpoint when you have a specific Channel3 product ID and need to surface similar or alternative products, especially when you need fine-grained filtering by price, brand, category, condition, availability, age group, or geography. Prefer this over a general search when the similarity anchor is a known product rather than a free-text query.
Side effects
- Invalid or unknown product_id returns empty results or an error
- Unsupported country/currency/language combination may return an error
- limit out of range (below 1 or above 30) causes a validation error
- Invalid filter values (e.g. unknown brand_id or category_id) may return empty or unfiltered results
- Payment failure via x402 protocol blocks the request
- Rate limiting or quota exceeded may return a 429 error
