Pay-per-call token data for RUNE via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides on-demand token data for RUNE (THORChain) through the x402 payment protocol. Each call costs $0.02, paid in USDC on the Base network. No API keys or accounts are required — callers attach an x402 payment header and receive a JSON response.
The endpoint is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs, all uniformly priced at $0.02 per request. The specific `/api/v1/tokens/RUNE` path suggests it returns token-level information for RUNE, likely price or market data, though the exact response schema is not documented. The x402 challenge confirms the endpoint is live, accepts POST requests, and settles payments to a known address via USDC (contract 0x8335…) on Base.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further detail. There is no OpenAPI spec, no example request/response, and no description of the returned fields. Callers should expect a JSON payload but will need to experiment to determine the exact structure.
