OHLCV candlestick data for OCEAN token, paid per-request via x402 on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the OCEAN cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a suite of data, analytics, AI, finance, and utility APIs all payable per-request via the x402 protocol on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on Base (contract 0x8335…2913) using the x402 exact-payment scheme. The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (two US cents) given USDC's 6-decimal precision. No API keys, subscriptions, or rate limits are advertised — callers simply attach an X-PAYMENT header with each request.
Documentation beyond the landing page is sparse: the /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no additional technical detail. The exact request parameters (e.g., time range, interval/granularity, pagination) and response schema are not documented in the crawled material, so callers will need to experiment or inspect the endpoint directly. The endpoint is confirmed live via a 402 challenge captured during probing.

Quality
The endpoint is confirmed live via a valid 402 challenge and pricing is clear ($0.02/request in USDC on Base). However, there is no documented request schema, no response schema, no examples, and all documentation pages returned only a wallet-connect stub. The listing is essentially a stub with confirmed liveness.
