What it does

This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the GRT (The Graph) cryptocurrency 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 and settled via the x402 protocol on the Base network using USDC.

The endpoint is accessed via HTTP POST and requires an X-PAYMENT header conforming to the x402 exact-payment scheme. The maximum amount required per call is 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimal places. There are no API keys, no rate limits, and no subscription commitments — each request is individually paid for on-chain.

Documentation on the site is extremely sparse: the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. As a result, the exact request body schema (e.g., supported time intervals, date ranges, or pagination parameters) and the response format are unknown. The endpoint is confirmed live via a valid 402 challenge, but callers will need to experiment or contact the provider to determine the full request/response contract.

Quality

The endpoint is confirmed live via a valid x402 402 challenge with clear pricing ($0.02 USDC on Base). However, documentation is essentially nonexistent — all doc pages render only 'Connect wallet'. No request body schema, response schema, or usage examples are available, making this effectively a stub listing.

Warnings

  • —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'
  • —Request body schema is unknown; callers must guess or reverse-engineer required parameters
  • —Response format and fields are undocumented
  • —No OpenAPI spec or AI plugin manifest provided
