Technical details
Endpoint
GEThttps://collectablespulse.theaslangroupllc.com/api/collect/value?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need current market pricing or recent sold comparables for a specific collectible item, especially graded cards, coins, comics, vinyl, watches, or sneakers. Prefer this over general search when you need grade-specific pricing (PSA/BGS/CGC) with actual transaction data rather than listed prices.
Side effects
- Item not found in database — obscure or newly released collectibles may return no data
- Insufficient recent sales data for rare high-grade items — comparables may be sparse or dated
- Ambiguous item description — may return multiple matches requiring clarification
- Grade or grading service not recognized — returns error or defaults to raw/ungraded pricing
- Rate limit or payment failure — returns 402 or 429 error
