What it does

This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the DAI cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a suite of data, analytics, AI, finance, and utility APIs all gated behind the x402 payment protocol on the Base network.

The endpoint is live and returns a 402 challenge requesting payment in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base). The maximum amount required per request is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals). Payment is made via the x402 "exact" scheme, with a 300-second timeout. No API keys or rate limits are advertised — access is purely pay-per-request.

Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no further content. The specific request body schema and response format for the DAI OHLCV endpoint are not documented anywhere in the crawled material. The endpoint accepts POST requests and returns application/json. Without documentation, the exact request parameters (e.g., time range, interval/granularity) and response fields must be inferred from the endpoint name and common OHLCV conventions.

Quality

0.35/ 1.00

The endpoint is live and returns a valid x402 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no documentation for request parameters or response schema — the docs pages are all blank wallet-connect stubs. The request example above is entirely inferred from OHLCV conventions and may not match the actual API contract.

Warnings

  • —No API documentation available — all doc pages return only a 'Connect wallet' prompt with no content.
  • —Request body schema and response format are unknown; the example_request_json is speculative based on common OHLCV conventions.
  • —The endpoint is part of a platform with many diverse APIs (AI, analytics, finance, utils) all at $0.02 — the actual data sources and quality are unverified.
