x402-gated NFT data endpoint on Base, pay-per-request with USDC at $0.02/call.
What it does
This endpoint at `/api/v1/nfts/95` is part of the lowpaymentfee.com platform, which offers a collection of pay-per-request APIs gated via the x402 protocol. The specific endpoint appears to serve NFT-related data (resource ID 95), though the exact response payload is not documented. Payment is settled on the Base network using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals). The endpoint accepts POST requests and returns `application/json`.
The broader lowpaymentfee.com platform advertises multiple API categories — data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced uniformly at $0.02 per request. The platform emphasizes no API keys, no rate limits, and instant access via x402 payment headers. However, there is no OpenAPI specification, no detailed documentation for individual endpoints, and no example request/response bodies available from the crawled pages. The NFT endpoint specifically (`/api/v1/nfts/95`) is not listed on the homepage's catalog, making its exact functionality unclear.
The x402 challenge was successfully captured with a 402 response, confirming the endpoint is live. The payment timeout is 300 seconds. No authentication beyond the x402 payment header is required.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documentation for this specific NFT endpoint, no example request/response bodies, and the endpoint isn't even listed on the provider's homepage catalog. Functionality must be inferred from the URL path alone.
