Example prompt: I just found a 1952 Topps Mickey Mantle baseball card I'm thinking about buying — can you run it through the CollectablesPulse authentication guide and tell me the red flags to watch for, which authentication services I should use, any DIY checks I can do, and how to buy it safely?

## When to prefer this

Use this endpoint when a collector, investor, or buyer needs to assess whether a specific collectible is genuine before purchasing or selling, especially when professional grading has not yet been performed. Ideal for pre-purchase due diligence or educating an agent about forgery detection in a given collectible category.

## Known failure modes

- Missing or ambiguous item description may return generic guidance not tailored to the specific collectible
- Unknown or unsupported collectible category may result in limited red flag coverage
- Payment failure (non-payment of 0.1 USDC) will block access to the response
- Highly niche or obscure items may not have well-established authentication services listed
