ICP OHLCV candlestick data 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 Internet Computer (ICP) cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a suite of data, AI, finance, and utility APIs all gated behind 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 price is $0.02 per request (20,000 base units of USDC with 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each call is independently paid.
The broader lowpaymentfee.com platform lists endpoints across categories including analytics/metrics, AI inference (sentiment, summarization, classification, embeddings), finance (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities. All share the same $0.02/request pricing model. Documentation beyond the landing page is sparse — the /docs, /pricing, and /README pages all render only a wallet-connect prompt with no additional technical detail. The specific request body schema and response format for the ICP OHLCV endpoint are not documented, so callers will need to experiment or inspect the response to determine supported parameters (e.g., time range, interval).

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base). However, there is no documentation for the request body schema, response format, or supported parameters. The /docs, /pricing, and /README pages are all empty wallet-connect stubs. No OpenAPI spec or examples are available, making this effectively a stub listing.
Warnings
- —No documentation available — /docs, /pricing, and /README pages all render only a wallet-connect prompt with no technical content.
- —Request body schema and response format for the OHLCV endpoint are completely undocumented; callers must guess or reverse-engineer parameters.
- —No OpenAPI specification or example responses provided by the provider.
- —The platform lists many endpoint categories but it is unclear how mature or complete each one is.
