Side effects
- 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
