OHLCV candlestick data for 1INCH token, paid per-request via x402 on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for the 1INCH cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a suite of data, analytics, AI, finance, and utility APIs all payable per-request using the x402 protocol on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on Base (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a cost of $0.02 per request (maxAmountRequired of 20,000 base units with USDC's 6 decimals). No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The platform advertises no rate limits and instant access.
Documentation is extremely sparse. The landing page lists available endpoints and pricing, but the /docs, /pricing, 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 parameters (e.g., time range, interval, exchange). The OHLCV endpoint itself is not listed on the homepage (which shows /crypto/quotes and /crypto/gas but not /crypto/{symbol}/ohlcv), so its exact capabilities and input parameters are inferred from the endpoint path and common OHLCV API conventions.

Quality
The endpoint is live (returns a valid x402 402 challenge) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no documentation of request parameters or response format, no examples, and the specific /crypto/1INCH/ohlcv path is not even listed on the provider's homepage. Effectively a stub listing.
