What it does

This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for the STX (Stacks) cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a suite of data, analytics, AI, finance, and utility APIs all payable per-request via the x402 protocol on the Base network.

The endpoint is accessed via HTTP POST and costs $0.02 per request, settled in USDC on Base (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). No API keys or accounts are required — payment is handled inline via the X-PAYMENT header using the x402 protocol. The platform advertises no rate limits and instant access.

The specific request and response schemas for this OHLCV endpoint are not documented in the crawled material. The broader lowpaymentfee.com site lists many endpoints across categories (crypto, finance, AI, infrastructure) all at the same $0.02 price point, but detailed per-endpoint documentation was not available at crawl time. The endpoint is confirmed live, returning a valid x402 402 challenge.

Quality

0.40/ 1.00

The endpoint is confirmed live with a valid x402 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format for the OHLCV endpoint specifically, and the docs/pricing/API pages returned only 'Connect wallet' with no substantive content. The listing is functional but largely a stub in terms of developer documentation.

Warnings

  • —No request or response schema documented for this endpoint — input parameters (e.g., time range, interval) are unknown
  • —Documentation pages (/docs, /api, /pricing, /README) returned no useful content at crawl time
  • —The platform lists many endpoints at the same price; unclear whether all are fully implemented or placeholders
