OHLCV candlestick data for ATOM (Cosmos), paid per-request via x402 on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for the ATOM (Cosmos) cryptocurrency. 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 at $0.02 per request (maxAmountRequired of 20,000 base units with USDC's 6 decimals). There are no API keys, no rate limits, and no subscription commitments — callers simply attach an x402 payment header to each request.
The broader lowpaymentfee.com platform lists additional crypto endpoints (token quotes, gas estimates, price feeds, exchange rates) as well as AI/ML endpoints (sentiment analysis, summarization, classification, embeddings) and infrastructure utilities (geocoding, validation, conversion). All share the same $0.02/request pricing model. Documentation beyond the landing page is sparse — the /docs, /pricing, and /README pages all appear to require a wallet connection and returned no substantive content during crawl.

Request
{}Endpoint
Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no documented request parameters (timeframe, date range, etc.), no example response, and the docs/pricing/README pages returned no content. The actual request and response shapes must be guessed.
Warnings
- —No documentation available — /docs, /pricing, and /README pages all returned only a 'Connect wallet' prompt with no API details.
- —Request body schema is unknown: required parameters (e.g., timeframe, start/end dates) are not documented.
- —Response schema is unknown: no example response or output schema provided.
- —The platform lists many diverse endpoints (AI, geocoding, finance) all at the same price, which may indicate a generic template rather than deeply specialized services.
