What it does

This endpoint at lowpaymentfee.com provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the PERP perpetual futures token. It is part of a broader suite of finance and crypto APIs offered by the same provider, 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 returns JSON. Payment is handled inline via the X-PAYMENT header — no API keys, accounts, or rate limits are required. The x402 challenge confirms the endpoint is live, advertising a max amount of 20,000 base units of USDC (0.02 USD) per call, paid to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base.

Documentation is extremely sparse. The provider's docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of accepted parameters (e.g., timeframe, date range, trading pair details). The endpoint path suggests it returns PERP-specific OHLCV data, but the exact request format and response structure must be discovered experimentally.

Quality

0.30/ 1.00

The x402 challenge is live and confirms pricing and payment details, but there is zero documentation: no OpenAPI schema, no request/response examples, no parameter descriptions. The docs pages all render only a wallet-connect prompt. The endpoint's behavior must be discovered experimentally.

Warnings

  • —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content
  • —No OpenAPI or request/response schema provided; request parameters and response format are unknown
  • —Endpoint is PERP-specific; unclear if other trading pairs are supported at this path
  • —Provider appears to host many endpoints across diverse categories (AI, finance, utils) — breadth may indicate a generic wrapper rather than a specialized data source
