x402-gated NFT data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at `/api/v1/nfts/47` 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 resource at `/nfts/47` is labeled "Premium API Access" and returns JSON data when paid for via the x402 protocol. Payment is settled on the Base network using USDC (contract `0x8335…2913`) at a cost of $0.02 per request (20,000 base units with 6 decimals).
The platform advertises a simple pricing model: $0.02 per request across all endpoints, with no API keys, no rate limits, no minimums, and instant access. The x402 challenge was successfully captured with version 1, confirming the endpoint is live. The accepted payment scheme is "exact" with a maximum timeout of 300 seconds. The endpoint expects HTTP POST requests.
Note that the specific data returned by `/api/v1/nfts/47` is not documented — the provider's landing page lists many endpoint categories but does not include an NFT-specific section, and no OpenAPI schema or detailed documentation was found. The endpoint's actual response payload and fields are unknown beyond the stated MIME type of `application/json`.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation for the /nfts/47 resource specifically — no OpenAPI schema, no response examples, and the NFT endpoint category isn't even listed on the provider's landing page. The actual data returned is completely unknown.
