What it does

This endpoint provides XRP OHLCV (Open, High, Low, Close, Volume) candlestick data through the x402 payment protocol. It is hosted on lowpaymentfee.com, a platform offering a variety of pay-per-request APIs spanning data analytics, AI/ML, finance, and infrastructure — all gated behind x402 micropayments settled in USDC on the Base network.

The endpoint accepts POST requests and returns JSON. Each call costs $0.02 (20,000 base units of USDC with 6 decimals) paid via the x402 X-PAYMENT header. There are no API keys, no rate limits, and no subscription commitments — you pay per request using on-chain USDC. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base mainnet, with a maximum timeout of 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. The exact request body schema (e.g., which time intervals or date ranges are supported) and the response format are not documented in any crawled material. The endpoint is confirmed live via a valid 402 challenge, but consumers should expect to experiment with the POST body to discover accepted parameters.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no documentation for request parameters, response schema, or usage examples — the docs pages are empty. The listing is effectively a stub with only the payment challenge and homepage listing as evidence.

Warnings

  • No API documentation available — docs, pricing, and README pages all render only 'Connect wallet' with no content.
  • Request body schema and response format are completely undocumented; consumers must reverse-engineer the API.
  • No examples of successful responses are available from any crawled source.
