Check SHIB wallet balances via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns SHIB (Shiba Inu) wallet balance data, gated behind an x402 payment challenge. 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/SHIB/balance` accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, requiring a maximum payment of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 "exact" scheme to the provider's wallet. No API keys or rate limits are advertised; access is granted purely through per-call micropayment.
Documentation is extremely sparse. The provider's 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 beyond the x402 outputSchema stub, and no example payloads. The actual data source for SHIB balances (whether on-chain lookup, third-party aggregator, etc.) is not disclosed. Users should treat this as a minimally documented endpoint and test with a single paid call before relying on it in production.

Quality

Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.
- —Request body schema is inferred (address field); no official specification exists.
- —Response format is completely unknown — no example or schema provided.
- —Data source for SHIB balances is undisclosed; unclear if this queries on-chain data or a third-party service.
- —The provider hosts many endpoints across diverse categories (AI, analytics, finance, utils) all at $0.02 — quality and reliability of each is unverified.
