What it does

This endpoint at lowpaymentfee.com returns the wallet balance for the STORJ token. 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 use the x402 payment protocol, settling in USDC on the Base network.

The specific endpoint `/api/v1/wallet/STORJ/balance` accepts POST requests and returns JSON. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, which has 6 decimals), equating to $0.02 per request. Payment is made via the "exact" scheme to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.

Documentation 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 spec, no request/response schema, and no usage examples available from the crawled material. The endpoint is confirmed live (402 challenge returned), but the actual response format after payment is unknown. The provider advertises no API keys, no rate limits, and instant access across all their endpoints.
