NEO liquidity data via pay-per-call x402 on Base (USDC, $0.02/request)
What it does
This endpoint provides DeFi liquidity data for the NEO token, accessible through the x402 payment protocol. It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance/Web3, and infrastructure endpoints — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required.
Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge advertises a maxAmountRequired of 20,000 base units, which equals $0.02 given USDC's 6 decimals. The endpoint accepts POST requests and returns application/json. No request body schema or response schema is documented beyond the x402 challenge's outputSchema stub.
Documentation on the site is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no example requests or responses, and no detailed description of what fields the liquidity endpoint returns. Users should expect to experiment or contact the provider for specifics on the response payload.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples. The actual data returned by the liquidity endpoint is entirely unknown.
