Punk fair value

A fair value price estimate for the specified CryptoPunk NFT, likely expressed as an ETH or USD amount representing the model's assessment of what the punk should be worth based on its traits and market data.
Example use cases
Verify punk acquisition price fairness
“I'm looking at CryptoPunk #4521 listed for 8 ETH right now. Can you tell me what it should actually be worth so I know if I'm getting a good deal?”
Portfolio valuation for collector
“I own CryptoPunk #891 and I'm thinking about selling it. What's a reasonable price I should be asking for it based on its traits?”
Identify undervalued market opportunities
“Check the fair value of CryptoPunk #2847 for me. I think it might be underpriced compared to similar punks on the market right now.”
Technical details
Endpoint
POSThttps://api.punkpredictor.xyz/agents/v2/fair-priceWhen to prefer
Use this endpoint when you need a model-driven fair value estimate for a specific CryptoPunk NFT by its numeric ID. Prefer this over floor price lookups when you want a trait-adjusted valuation rather than a raw market price, or when evaluating whether a listed punk is over- or under-priced relative to its intrinsic characteristics.
Side effects
- Invalid punk ID (outside 0-9999 range) returns validation error
- Payment failure (insufficient USDC or x402 protocol error) blocks the request
- Punk ID not provided returns missing field error
- Service unavailable or model inference error returns 5xx
