OHLCV candlestick data for LEO token, paid per-request via x402 on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the LEO cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a broad suite of data, analytics, AI, finance, and utility APIs — all payable per-request via the x402 protocol on the Base network using USDC.
The endpoint is live and returns a standard x402 payment challenge (HTTP 402) when called without payment. Each request costs $0.02 (20,000 base units of USDC, which has 6 decimals). Payment is made via the x402 "exact" scheme to a specified wallet address on Base. No API keys, rate limits, or subscriptions are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
Documentation on the site is extremely sparse. The /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no usage examples available from the crawled material. The endpoint accepts POST requests and returns application/json, but the exact request body format and response structure for OHLCV data are not documented in any accessible source.

Quality
The endpoint is live and returns a valid x402 challenge, confirming it exists and accepts payment. However, there is zero documentation on request parameters, response schema, or usage examples. The /docs and related pages are empty. Without knowing what to POST or what the response looks like, this is effectively a stub listing.

- —No OpenAPI spec or request/response schema provided
