Pay-per-call NEO token data via x402 on Base — $0.02/request in USDC, no API keys required.
What it does
This endpoint at lowpaymentfee.com provides token data for NEO via a simple POST request, paid per-call using the x402 protocol. The endpoint is live and returns a 402 challenge requiring payment of up to 0.02 USDC (20,000 base units of USDC on Base network) per request. No API keys, accounts, or rate limits are advertised — callers simply attach an X-PAYMENT header with a valid x402 payment proof to receive the response.
The provider operates a broader platform offering dozens of endpoints across categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced uniformly at $0.02 per request. This specific endpoint falls under the Finance & Web3 category and appears to return token-level information for NEO, though the exact response schema is not documented. Payment settles in USDC on the Base L2 network to the address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical content. There is no OpenAPI spec, no response schema, and no example responses available. The endpoint is confirmed live via the 402 challenge, but the actual data returned after payment is unknown.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no documentation, no OpenAPI spec, no response schema, and no example responses. The docs pages are empty. The actual data returned after payment is entirely unknown, making this effectively a stub listing.
