x402-gated NFT data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at `/api/v1/nfts/84` is part of the lowpaymentfee.com platform, which offers a collection of pay-per-call APIs gated via the x402 protocol on the Base network. The specific endpoint appears to serve NFT-related data (resource ID 84), though the exact response payload is not documented. Payment is settled in USDC (contract `0x8335…2913` on Base) at $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required; callers simply attach an `X-PAYMENT` header with a valid x402 payment proof.
The broader lowpaymentfee.com platform advertises endpoints across several categories: data & analytics (metrics, reports, exports, insights), AI & machine learning (sentiment analysis, text summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are uniformly priced at $0.02 per request. However, this specific listing covers only the `/api/v1/nfts/84` endpoint, which is not listed on the site's main catalog page, so its exact functionality is unclear.
The endpoint is live and returns a proper x402 challenge (HTTP 402) when called without payment. The method is POST. No OpenAPI schema, detailed documentation, or example responses were found during crawling — the site's documentation and pricing pages require a wallet connection to view.
