What it does

This endpoint at `/api/v1/nfts/98` is part of the lowpaymentfee.com platform, a collection of x402-protocol pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities. The specific resource appears to serve NFT-related data (inferred from the URL path `/nfts/98`), though the provider's landing page does not list this particular endpoint among its advertised APIs, and no detailed documentation or response schema is available.

Payment is handled via the x402 protocol on the Base network. The challenge advertises a maximum amount of 20,000 base units of USDC (contract `0x8335…2913`, 6 decimals), which equals $0.02 per request. Settlement is to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`. The endpoint accepts HTTP POST, requires no API keys, and claims no rate limits. The x402 challenge was successfully captured (HTTP 402), confirming the endpoint is live.

Because the endpoint is not explicitly listed on the provider's homepage and no OpenAPI schema, example responses, or detailed documentation were found, the actual data returned is uncertain. The NFT path segment suggests it may return metadata or ownership information for a specific NFT (ID 98), but this is speculative. Callers should be prepared for an unknown JSON response structure.

Quality

0.30/ 1.00

The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI schema, no example responses, and the /nfts/98 path is not listed among the provider's advertised APIs. The actual data returned is unknown, making this effectively a stub listing.

Warnings

  • Endpoint /api/v1/nfts/98 is not listed on the provider's homepage among advertised APIs
  • No response schema or example response available — actual output format is unknown
  • No OpenAPI spec, README, or detailed documentation could be retrieved (pages returned only 'Connect wallet')
  • The purpose and content of this specific NFT endpoint is inferred solely from the URL path
