OHLCV candlestick data for RPL (Rocket Pool) via x402 micropayment on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for the RPL (Rocket Pool) cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a broad suite of pay-per-request APIs spanning crypto market data, finance, AI/ML inference, analytics, and utility services — all gated via the x402 payment protocol on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header containing a signed USDC payment on Base. The maximum amount required per request is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. There are no API keys, no rate limits, and no subscription commitments — each call is independently paid.
The platform advertises similar endpoints for token quotes, gas estimates, exchange rates, and price feeds, all at the same $0.02/request price point. Documentation beyond the landing page is sparse; the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. The exact request body schema and response fields for the OHLCV endpoint are not documented, so callers should expect standard OHLCV fields (timestamp, open, high, low, close, volume) but may need to experiment with parameters like time range or interval.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation for request parameters or response schema. The docs, API, pricing, and README pages are all empty beyond a wallet-connect prompt. The listing is effectively a stub with only the x402 challenge and landing page to go on.

- —No response schema or example response documented anywhere
- —Docs, API, pricing, and README pages all render only 'Connect wallet' with no content
