OHLCV candlestick data for ARB (Arbitrum) via pay-per-request x402 on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for the ARB (Arbitrum) token, served through the x402 payment protocol. Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The caller simply includes an X-PAYMENT header with a valid x402 payment proof and receives JSON data in return.
The endpoint is part of a broader suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services. All endpoints on the platform follow the same $0.02-per-request pricing model settled in USDC on Base. The specific endpoint at `/api/v1/crypto/ARB/ohlcv` accepts POST requests and returns application/json responses.
Documentation beyond the landing page is sparse — the /docs, /pricing, and /README pages all resolve to a minimal "Connect wallet" prompt with no further technical detail. There is no published OpenAPI schema, no request/response examples, and no documentation of supported query parameters (e.g., time range, candle interval). Prospective users should expect to experiment with the endpoint or contact the provider for integration guidance.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and no meaningful documentation beyond the landing page. The actual request body format and response structure are entirely unknown.
Warnings
- —No documentation available — /docs, /pricing, /README all return only a 'Connect wallet' prompt with no technical content.
- —No OpenAPI or JSON schema published; request parameters (timeframe, interval, etc.) are undocumented.
- —Response format is unknown — no example responses are available anywhere in the crawl.
- —The broader platform lists many diverse endpoints (AI, analytics, utilities) all at $0.02; unclear whether all are fully implemented.
