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.

Quality

0.35/ 1.00

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.
