NFT metadata endpoint on Base, pay-per-call via x402 with USDC at $0.02/request.
What it does
This endpoint serves NFT metadata for token ID 96 via the x402 payment protocol. It is hosted on lowpaymentfee.com, a platform that offers a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities. All endpoints on the platform share a uniform pricing model of $0.02 per request, settled in USDC on the Base network with no API keys, rate limits, or upfront commitments required.
The specific endpoint at `/api/v1/nfts/96/metadata` accepts POST requests and returns JSON. The x402 challenge confirms it is live, advertising a max amount of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 `exact` scheme to the payTo address, with a 300-second timeout window.
Because the endpoint path is scoped to a single NFT token ID (96), it likely returns metadata (name, description, image, attributes) for that specific NFT. The broader platform lists many other endpoints but no OpenAPI schema, request/response examples, or detailed documentation was found during the crawl. The actual content and structure of the metadata response is unknown.

Quality
