Query GALA wallet balances via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns GALA token wallet balance data, accessible through the x402 payment protocol. It is part of a broader suite of pay-per-call APIs offered by the same provider, spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities. All endpoints on the platform share a uniform $0.02-per-request pricing model settled in USDC on the Base network.
The specific endpoint `/api/v1/wallet/GALA/balance` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the payTo address on Base. No API keys or accounts are required — access is granted per-request upon valid payment. The x402 challenge was confirmed live, returning a proper 402 response with version 1 of the protocol.
Documentation beyond the landing page is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no example request/response payloads, and no description of what fields the balance response contains or what parameters the POST body expects. The endpoint's actual data source and accuracy guarantees are unknown.
