Query EGLD wallet balance via x402 micropayment on Base network for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides EGLD (MultiversX/Elrond) wallet balance lookups, gated behind an x402 payment challenge. It accepts POST requests and returns JSON. Payment is settled in USDC on the Base network at a cost of $0.02 per call (20,000 base units of USDC with 6 decimals).
The provider operates a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all at the same $0.02/request price point. No API keys or rate limits are advertised; access is granted instantly upon valid x402 payment. The x402 challenge specifies version 1, scheme "exact", with a 300-second timeout window.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema beyond the x402 outputSchema stub, and no example payloads. The actual data source for EGLD balances is unknown.
