x402-gated NFT data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at `/api/v1/nfts/82` is part of the lowpaymentfee.com platform, a collection of x402-protocol pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities. The specific endpoint appears to serve NFT-related data (resource ID 82), though the exact response payload is not documented. Payment is settled on the Base network using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) at a cost of $0.02 per request (20,000 base units with 6 decimals). The endpoint uses the x402 "exact" payment scheme and accepts POST requests.
The broader platform advertises a uniform $0.02/request pricing model across all endpoints with no API keys, no rate limits, and no minimum commitments. Other endpoints on the same platform cover sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, geocoding, and more. However, there is no OpenAPI schema, no detailed documentation for request/response formats, and no examples available for this specific NFT endpoint. The endpoint is confirmed live via a valid 402 challenge response.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, but there is no documentation, no OpenAPI schema, no request/response examples, and the description 'Premium API Access' is entirely generic. The NFT-specific functionality is only inferred from the URL path. Effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available for this endpoint
- —No request body or response body examples documented anywhere
- —Endpoint purpose inferred solely from URL path '/api/v1/nfts/82' — actual functionality is unknown
- —The provider landing page shows many endpoints but none match this specific NFT path, suggesting it may be unlisted or experimental
