RUNE liquidity data via x402 micropayment on Base network, $0.02 per request.
What it does
This endpoint provides RUNE (THORChain) liquidity data through the x402 payment protocol. It is hosted on lowpaymentfee.com, a platform offering a variety of pay-per-request APIs spanning DeFi, analytics, AI, and utility categories. The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network at $0.02 per call (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — access is gated solely by the x402 payment header.
The specific endpoint `/api/v1/defi/RUNE/liquidity` is not listed on the provider's landing page among the advertised APIs, though the landing page does show a broad set of finance and crypto endpoints at similar price points. The endpoint was confirmed live via a 402 challenge response. Documentation beyond the landing page is effectively empty (all doc/pricing/README pages only show a "Connect wallet" prompt), so the exact request body schema and response fields for this RUNE liquidity endpoint are unknown.
The provider advertises uniform $0.02 pricing across all endpoints, no minimums, no commitments, and settlement on the Base network. The x402 challenge confirms USDC (contract 0x8335…2913) as the payment asset, with a 300-second timeout window.
