OHLCV candlestick data for CHZ (Chiliz) via pay-per-request x402 on Base
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for the CHZ (Chiliz) cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a suite of data, AI, finance, and utility APIs all payable per-request via the x402 protocol on the Base network.
The endpoint is live and returns a standard x402 402 challenge when called without payment. Each request costs $0.02 in USDC (USD Coin) on Base (asset address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The payment scheme is "exact", meaning the caller pays a fixed amount per call with no subscription or API key required. The x402 challenge specifies a maxAmountRequired of 20000 base units, which at 6 decimals for USDC equals $0.02, consistent with the site's advertised pricing.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" stub with no further content. There is no OpenAPI schema, no request/response examples, and no description of accepted parameters (e.g., time range, interval, pagination). The endpoint accepts POST requests based on the outputSchema in the x402 challenge. Without documentation it is unclear what request body fields are expected or what the response structure looks like. Users should expect a JSON response containing OHLCV candlestick fields for CHZ but will need to experiment to determine the exact contract.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear at $0.02 USDC per request. However, there is no OpenAPI schema, no request/response documentation, no examples, and all doc pages are empty stubs. The actual request body format and response structure are completely unknown, making this effectively a stub listing.
