OHLCV candlestick data for INJ (Injective) via pay-per-call x402 on Base
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the Injective (INJ) cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a suite of data, AI, finance, and utility APIs all payable per-request via the x402 protocol on the Base network.
The endpoint is live and returns a standard x402 402 challenge when called without payment. Each request costs $0.02 in USDC (the asset at contract 0x8335…2913 on Base, which is the canonical USDC contract). Payment is made via the x402 "exact" scheme — a single micropayment per call with no API keys, subscriptions, or rate limits required. The response MIME type is application/json.
Documentation on the site is extremely sparse — the docs, pricing, API, 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 query parameters (e.g., timeframe, date range). The endpoint path suggests it returns OHLCV data for INJ specifically, but the exact request format and response shape must be inferred or discovered experimentally.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI schema, no request/response examples, and no description of accepted parameters. The response shape is entirely unknown. This is effectively a stub listing.
