x402-gated NFT data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at `/api/v1/nfts/80` is part of the lowpaymentfee.com platform, a collection of x402-protocol pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities. The specific endpoint appears to serve NFT-related data (resource path `/nfts/80`), though the exact response payload is not documented beyond the generic "Premium API Access" label. Payment is settled on the Base network using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) at a maximum cost of $0.02 per request (20,000 base units ÷ 10^6 decimals = $0.02).
The endpoint is live and returns a valid x402 version-1 challenge when called without payment. It accepts HTTP POST requests and returns `application/json`. No API keys or rate limits are advertised — access is gated purely by the x402 micropayment protocol. The platform advertises a uniform $0.02/request pricing across all its endpoints.
Documentation is minimal: there is no OpenAPI spec, no request/response schema beyond the x402 challenge's `outputSchema` stub, and the crawled docs pages (`/api`, `/pricing`, `/README`) all resolve to a wallet-connect prompt with no additional content. The NFT-specific functionality of this endpoint (e.g., what data it returns for ID 80, whether the ID is a parameter) must be inferred from the URL path alone.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI spec, no request/response schema, no documentation beyond a generic label, and the NFT-specific functionality is entirely undocumented. The crawled pages provide no additional detail. This is effectively a stub listing.
