What it does

This endpoint provides OHLCV (open, high, low, close, volume) candlestick data for the IOTA cryptocurrency. It is part of the lowpaymentfee.com platform, which offers a suite of pay-per-request APIs spanning data analytics, AI/ML inference, finance, and crypto market data. The endpoint is accessed via HTTP POST and is gated by the x402 payment protocol, settling in USDC on the Base network.

Pricing is $0.02 per request (20,000 base units of USDC with 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each call is paid individually via an X-PAYMENT header containing a signed x402 payment proof. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base.

Documentation on the site is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further detail. There is no OpenAPI schema, no request/response examples, and no description of accepted parameters (e.g., time range, interval/granularity). The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation means callers will need to experiment or contact the provider to discover the exact request format and response shape.

Quality

0.30/ 1.00

The endpoint is confirmed live via a valid 402 challenge, but there is zero documentation on request parameters, response schema, or usage examples. The docs/pricing/API pages are all blank beyond a wallet-connect prompt. This is effectively a stub listing.

Warnings

  • —No API documentation available — request parameters and response format are unknown
  • —No OpenAPI or output schema provided beyond basic HTTP method info
  • —Docs, pricing, and API pages on the site render only 'Connect wallet' with no content
  • —Cannot verify what data is actually returned without making a paid request
