What it does

This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the Aptos (APT) cryptocurrency. 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 and settled via the x402 protocol using USDC on the Base network.

The endpoint accepts POST requests and is gated by an x402 payment challenge. Callers must include an X-PAYMENT header with a valid payment proof. The maximum amount required per call is 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals). Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base, with a timeout of 300 seconds. The response MIME type is application/json.

Documentation beyond the landing page is sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. No OpenAPI schema, request/response examples, or parameter documentation were found. The specific request body format (e.g., time range, interval, pagination) and response schema for the OHLCV data are not documented in the crawled material, so callers will need to experiment or contact the provider.

Quality

0.35/ 1.00

The endpoint is live and returns a well-formed x402 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response documentation, no examples, and all doc pages render only a wallet-connect prompt. The specific parameters and response format for OHLCV data are entirely undocumented.

Warnings

  • —No request parameter documentation found — callers must guess or reverse-engineer the POST body format
  • —No response schema or example response available for the OHLCV data
  • —All documentation pages (/docs, /api, /pricing, /README) return only a 'Connect wallet' prompt with no technical content
  • —The platform lists many API categories but provides no detailed docs for any of them
