OHLCV candlestick data for OKB via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the OKB token. It is part of the lowpaymentfee.com platform, which offers a variety of pay-per-call APIs spanning crypto market data, finance, AI/ML inference, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint at `/api/v1/crypto/OKB/ohlcv` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0.02 USD per request, since USDC uses 6 decimals). Payment is made via the x402 `exact` scheme to a specified wallet address on Base. No API keys or account registration are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
Documentation beyond the landing page is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no description of request parameters (e.g., timeframe, date range), and no example responses. The endpoint is confirmed live (returns a proper 402 challenge), but without documentation it is difficult to know exactly what request body fields are expected or what the response payload looks like.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it exists and accepts payment. However, there is no OpenAPI schema, no documentation of request/response fields, and all doc pages render only 'Connect wallet'. The actual data contract is entirely unknown, making this effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no technical content.
- —No OpenAPI or JSON schema describing request parameters (timeframe, date range, etc.) or response format.
- —No example requests or responses available; request body and response structure are unknown.
- —The broader lowpaymentfee.com platform lists many diverse endpoints (AI, finance, utilities) all at $0.02 — the actual data quality and sources behind these endpoints are unverified.
