OHLCV candlestick data for TWT (Trust Wallet Token) via x402 micropayment on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for the TWT (Trust Wallet Token) cryptocurrency. It is part of the lowpaymentfee.com platform, which offers a suite of pay-per-request APIs spanning data analytics, AI/ML, finance, and infrastructure — all gated via the x402 payment protocol on the Base network.
The endpoint accepts POST requests and returns JSON. Each call costs $0.02 in USDC (the x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC on Base, which has 6 decimals, equaling $0.02). Payment is settled on-chain via the x402 "exact" scheme — no API keys, accounts, or rate limits are required. The caller simply includes an X-PAYMENT header with a valid payment proof.
Documentation beyond the landing page is extremely sparse. The /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no additional technical content. There is no OpenAPI spec, no request/response schema, and no usage examples available. The specific request parameters (e.g., time range, interval/granularity) and response format for the OHLCV data are unknown and must be discovered experimentally.
