What it does

This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the TRX (Tron) cryptocurrency. It is part of a broader suite of finance and crypto APIs offered at lowpaymentfee.com, all gated behind the x402 payment protocol on the Base network. Each request costs $0.02 in USDC, settled on-chain with no API keys, no rate limits, and no subscriptions required.

The endpoint accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, using the "exact" payment scheme with USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base. The max amount required is 20,000 base units, which at 6 decimals equals $0.02. Payment is made via the X-PAYMENT header per the x402 protocol.

Documentation beyond the landing page is sparse — the /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of accepted parameters (e.g., time interval, date range). The specific input fields and response structure must be inferred or discovered by making a paid request.

Quality

0.35/ 1.00

The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and no meaningful documentation — the docs pages all return only a wallet-connect prompt. Input parameters and response format are entirely unknown.

Warnings

  • —No API documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no technical content.
  • —No OpenAPI or JSON schema describing request parameters (e.g., interval, date range) or response format.
  • —Response structure and supported query parameters must be discovered empirically by making a paid call.
  • —The provider hosts many generic-sounding endpoints across unrelated domains (AI, geocoding, finance); actual data quality and sources are unverified.
