What it does

This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for the Uniswap (UNI) token. It is part of the lowpaymentfee.com platform, which offers a suite of data, AI, finance, and utility APIs all priced at $0.02 per request with no API keys, no rate limits, and instant access.

Payment is handled via the x402 protocol on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The maximum amount required per call is 20,000 base units, which equals $0.02 USD (USDC uses 6 decimals). The endpoint accepts POST requests and returns JSON. No authentication or API key is needed — callers simply attach an X-PAYMENT header with a valid x402 payment proof.

Documentation beyond the landing page is sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of the OHLCV payload format. The endpoint is confirmed live (returns a proper 402 challenge), but the exact request parameters (e.g., time range, interval) and response schema must be inferred or discovered experimentally.

Quality

The endpoint is live and returns a valid x402 402 challenge with clear pricing. However, there is no OpenAPI schema, no documented request parameters, no response examples, and all doc pages render only a wallet-connect prompt. The listing is essentially a stub with confirmed liveness.

Warnings

  • —No OpenAPI or request/response schema available — request parameters and response format are unknown
  • —All documentation pages (docs, API, pricing, README) return only a 'Connect wallet' prompt with no technical content
  • —OHLCV payload structure (supported intervals, time ranges, field names) must be discovered experimentally
