The endpoint is live and responds with an HTTP 402 Payment Required challenge when called via POST, consistent with the x402 protocol for pay-per-call APIs. The \"v2\" path segment suggests an iterated API with at least one prior version.\n\nNo public documentation, OpenAPI schema, pricing details, or usage examples were found during crawling — the origin server returns 404 on all standard documentation paths (/docs, /api, /pricing, /README). The x402 challenge object captured was empty, so the exact payment token, network, and per-call cost could not be determined from the probe alone. The domain name and path strongly imply the service estimates a fair market price for individual CryptoPunks, likely accepting a punk ID or trait set as input and returning a USD or ETH valuation.\n\nBecause nearly all details are inferred from the URL structure and protocol behavior rather than confirmed documentation, users should treat capability assumptions with caution until the provider publishes formal docs or an OpenAPI spec.","tags":[],"capabilities":["nft-valuation","cryptopunks","fair-price-estimation","x402-payment","pay-per-call"],"categories":["nft","crypto","valuation"],"synonyms":["CryptoPunk price","NFT appraisal","punk valuation","CryptoPunks fair value","NFT pricing API","punk price estimator"],"warnings":["x402 challenge object is empty — payment token, network, and per-call price are unknown","No public documentation, OpenAPI spec, or README found on the origin server","Request and response schemas are entirely inferred from the endpoint path; actual parameters may differ","Pricing cannot be confirmed; users should test with a small payment first"],"endpointUrl":"https://api.punkpredictor.xyz/agents/v2/fair-price","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x4f6e0faec10cf04b428ec9e34cd88ae04fba6062","amount":"5000000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300}]},"qualityScore":"0.200","qualityRationale":"The endpoint is live (402 on POST), but the x402 challenge body is empty, no documentation or schema exists at any crawled path, and pricing/payment details are completely unknown.
