OHLCV candlestick data for JST (JUST) token, paid per-request via x402 on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for the JST (JUST) cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a broad suite of pay-per-call APIs spanning crypto market data, finance, AI/ML inference, analytics, and utilities — 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 (USD Coin) on Base, settled on-chain with no API keys, no rate limits, and no subscriptions required. The x402 challenge confirms the asset is USDC at contract 0x8335…2913 on Base, with a maxAmountRequired of 20000 base units (i.e., $0.02 given USDC's 6 decimals).
Documentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail. The exact request body schema (e.g., time range, interval, exchange) and the response schema (field names, pagination) are not documented in any crawled material. Users should expect standard OHLCV fields but will need to experiment or inspect responses to confirm the exact format.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base). However, there is no documentation for the request body schema, response schema, or any usage examples. The /docs, /pricing, and /README pages are empty beyond a wallet-connect prompt. Effectively a stub listing.
Warnings
- —No request body schema documented — required POST fields for OHLCV queries (interval, time range, etc.) are unknown.
- —No response schema documented — field names and structure must be discovered empirically.
- —All documentation pages (/docs, /pricing, /README) returned only a 'Connect wallet' prompt with no technical content.
- —The platform lists many diverse API categories (AI, analytics, geocoding, etc.) at identical $0.02 pricing, which may indicate a generic template rather than fully implemented endpoints.
