Check RNDR token wallet balance via x402 micropayment on Base network for $0.02/request.
What it does
This endpoint at lowpaymentfee.com returns the balance of an RNDR (Render Token) wallet. It is part of a broader platform offering pay-per-call APIs across data analytics, AI/ML, finance/Web3, and infrastructure categories, all settled via the x402 protocol on the Base network using USDC.
The specific endpoint `/api/v1/wallet/RNDR/balance` accepts POST requests and is gated by an x402 payment challenge. The maximum amount required per call is 20,000 base units of USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made inline via the X-PAYMENT header — no API keys, accounts, or rate limits are required. The payment timeout is 300 seconds.
The platform advertises a uniform $0.02 per request pricing across all its endpoints. Documentation pages (docs, pricing, README) appear to be behind a wallet-connect gate and did not yield substantive content during crawling, so details about request/response schemas, supported parameters, and error handling are unknown. The endpoint is confirmed live via a valid 402 challenge response.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages are gated behind wallet-connect with no useful content. The purpose is inferred from the URL path alone; request body format and response structure are entirely unknown.
