x402-gated NFT data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at `/api/v1/nfts/58` is part of the lowpaymentfee.com platform, which offers a collection of pay-per-request APIs gated via the x402 protocol on the Base network. The specific endpoint appears to serve NFT-related data (resource ID 58), though the exact response payload is not documented. Payment is settled in USDC (contract `0x8335…2913` on Base) at $0.02 per call (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 & ML (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 is for the `/api/v1/nfts/58` path, which is not listed on the homepage catalog, so its exact functionality is unclear.
The endpoint is live and returns a proper x402 challenge (HTTP 402) when called without payment. It accepts POST requests. No OpenAPI schema, detailed documentation, or example responses were found in the crawl, so the actual data returned after successful payment remains unknown.
