x402-gated NFT data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides premium API access to NFT data (resource ID 87) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with an exact-scheme challenge requiring up to 20,000 base units (i.e., $0.02 per call, since USDC uses 6 decimals).
The endpoint is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access; callers simply attach an x402 payment header to each request.
This specific endpoint (/api/v1/nfts/87) is not documented in detail on the site's landing page, which lists other endpoint categories but does not enumerate NFT-specific routes. The response schema and accepted POST body fields are not documented in any crawled material, so the exact input/output contract must be discovered by making a paid call. The x402 challenge confirms the endpoint is live and accepting payment negotiations.

Quality
The x402 challenge is live and confirms pricing and network, but there is no documentation for this specific NFT endpoint — no input schema, no output schema, no example responses. The endpoint path (/api/v1/nfts/87) is not listed on the site's landing page, and the /api, /pricing, and /README pages returned only a wallet-connect stub with no useful content.
