OHLCV candlestick data for RSR (Reserve Rights) via per-request x402 micropayment on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for the RSR (Reserve Rights) cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a broad catalog of pay-per-call APIs spanning data analytics, AI/ML, finance, and infrastructure — all gated by the x402 payment protocol on the Base network.
The endpoint is accessed via HTTP POST and costs $0.02 per request, paid in USDC on Base. There are no API keys, no rate limits, and no subscription commitments; each call is individually settled through an x402 payment header. The x402 challenge confirms the endpoint is live, accepting payments to address 0x1A2B...85F3 with a max amount of 20,000 base units of USDC (i.e., $0.02 given 6 decimals).
Documentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail. No OpenAPI schema, request/response examples, or parameter documentation were found. The exact request body format and the structure of the OHLCV response are unknown and must be discovered experimentally. This limits confidence in integration without trial-and-error.

Quality
The x402 challenge is live and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no request/response examples, and no meaningful documentation — the docs pages all show only a wallet-connect prompt. The exact request parameters and response format for the OHLCV endpoint are entirely unknown.
Warnings

- —Request body schema and response format for the OHLCV endpoint are completely undocumented; integration requires experimentation.
- —No OpenAPI or ai-plugin manifest found.
- —The broader lowpaymentfee.com platform lists many endpoint categories but it is unclear how mature or reliable any individual endpoint is.
