Technical details
Endpoint
GEThttps://collectablespulse.vercel.app/api/collect/gradeWhen to prefer
Use this endpoint when a collector or investor agent needs to decide whether to submit an item for third-party grading and which of the major grading companies (PSA, BGS, CGC, PCGS, NGC) is most appropriate. Prefer this over generic web search when you need structured, actionable grading guidance with cost and turnaround data in a single call.
Side effects
- Unrecognized or insufficiently described item type returns generic or null recommendations
- Very obscure collectibles may not have grading service coverage
- Grading costs and turnaround times may be outdated if services change pricing
- Missing item condition input may result in incomplete worth-grading assessment
