x402-gated NFT data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at `/api/v1/nfts/35` is part of the lowpaymentfee.com platform, a collection of x402-protocol pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities. The specific resource appears to serve NFT-related data (inferred from the URL path `/nfts/35`), though the provider's landing page does not explicitly list this particular route among its advertised endpoints. The endpoint is live and returns a valid x402 challenge.
Payment is settled on the Base network using USDC (contract `0x8335…2913`) via the "exact" scheme. The `maxAmountRequired` is 20,000 base units, which at 6 decimals equals $0.02 per request. No API keys or rate limits are advertised; access is granted purely through the x402 payment header. The response MIME type is `application/json` and the endpoint accepts HTTP POST.
The broader lowpaymentfee.com platform advertises a uniform $0.02/request pricing model across all its endpoints, with categories including sentiment analysis, text summarization, embeddings, price feeds, gas estimates, geocoding, and more. Documentation beyond the landing page is minimal — the `/api`, `/pricing`, and `/README` routes all return only a "Connect wallet" prompt with no further technical detail.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documentation for request/response formats, no example payloads, and the specific /nfts/35 route is not listed on the provider's landing page. The broader site docs are essentially empty beyond the homepage listing.
