NEO OHLCV (open-high-low-close-volume) crypto market data via x402 micropayment on Base.
What it does
This endpoint serves NEO cryptocurrency OHLCV (open, high, low, close, volume) candlestick data behind an x402 paywall on the Base network. It is part of the lowpaymentfee.com platform, which offers a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services—all priced at $0.02 per call with no API keys, no rate limits, and no subscriptions required.
The specific endpoint at `/api/v1/crypto/NEO/ohlcv` accepts POST requests and returns JSON. Payment is settled on-chain via USDC on Base (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) using the x402 "exact" scheme. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02. The payment recipient address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3, and the payment timeout is 300 seconds.
Documentation on the site is extremely sparse—the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of accepted parameters (e.g., time range, interval/granularity). The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation means callers must experiment to discover the request format and response shape.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing, but there is no documentation, no OpenAPI schema, no request/response examples, and no description of accepted parameters. The listing is effectively a stub with only the payment challenge to go on.
Warnings
- —No documentation available—docs, API, pricing, and README pages all show only 'Connect wallet' with no content.
- —No OpenAPI or input/output schema provided; request parameters (timeframe, interval, etc.) are unknown.
- —No example responses available; the actual data format returned is unverified.
- —The endpoint path suggests NEO-specific data but the platform's generic '$0.02/request' pricing and broad API catalog raise questions about data source quality and freshness.
