What it does

This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for Ethereum Classic (ETC). It is part of the lowpaymentfee.com platform, which offers a suite of data, AI, finance, and utility APIs all priced at $0.02 per request, settled via the x402 protocol on the Base network using USDC.

The endpoint is accessed via HTTP POST and requires an X-PAYMENT header containing a valid x402 payment proof. The x402 challenge confirms the endpoint is live, accepting payments to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a maximum amount of 20,000 base units of USDC (i.e., $0.02, since USDC uses 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each call is independently paid.

Documentation on the site is extremely sparse. The docs, API reference, pricing, and README pages all render only a "Connect wallet" prompt with no additional content. The exact request body schema (e.g., which time intervals or date ranges are supported) and the response format are not documented. Users should expect a JSON response containing OHLCV candlestick fields, but the precise structure must be discovered empirically.

Quality

0.35/ 1.00

The x402 challenge is live and pricing is clear ($0.02/request in USDC on Base). However, there is no documentation for request parameters, response schema, or examples. The docs/pricing/README pages are all empty beyond a wallet connect prompt, making this effectively a stub listing.

Warnings

  • —No API documentation available — docs, pricing, and README pages all show only 'Connect wallet'
  • —Request body schema and response format are completely undocumented
  • —No example requests or responses available; users must discover the API shape empirically
  • —The endpoint's specific capabilities (supported intervals, date ranges, etc.) are unknown
