OHLCV candlestick data for IMX (Immutable X) via pay-per-request x402 on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for the IMX (Immutable X) cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a suite of data, AI, finance, and utility APIs all gated behind the x402 payment protocol on the Base network.
Each request costs $0.02 in USDC (USD Coin on Base, contract 0x8335…2913). The endpoint accepts POST requests and returns JSON. Payment is handled inline via the X-PAYMENT header per the x402 protocol — no API keys, accounts, or rate limits are required. The x402 challenge confirms the endpoint is live and accepting payments 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. There is no OpenAPI spec, no request/response schema, and no example payloads available. The exact POST body format (e.g., how to specify time range, interval, or other OHLCV parameters) is unknown and must be discovered experimentally.

Quality
The x402 challenge confirms the endpoint is live and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documented parameters, and no example payloads. The docs pages are empty. This is effectively a stub listing with confirmed liveness.
Warnings
- —No API documentation available — /docs, /pricing, /api, and /README pages all show only a wallet-connect prompt with no technical content.
- —No OpenAPI or JSON schema for request or response bodies; the required POST body format is unknown.
- —No example responses available; actual data structure of OHLCV output is unverified.
- —The endpoint description is generic ('Premium API Access') and does not describe the OHLCV functionality specifically.
