OHLCV candlestick data for SNX (Synthetix) via per-request x402 micropayment on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the SNX (Synthetix) cryptocurrency token. It is part of a broader suite of finance and crypto APIs hosted at lowpaymentfee.com, all payable per-request via the x402 protocol on the Base network using USDC.
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 advertises a maximum cost of 20,000 base units of USDC (6 decimals), which equals $0.02 per request. The provider's landing page confirms a flat $0.02/request pricing model across all endpoints.
The provider offers additional crypto endpoints (token quotes, gas estimates, price feeds, exchange rates) as well as AI/ML, analytics, and utility APIs, all at the same price point. Documentation beyond the landing page is sparse — the /docs, /pricing, and /README pages all render only a wallet-connect prompt with no further technical detail. No OpenAPI schema, request/response examples, or parameter documentation were found in the crawl.
