What it does

This endpoint at lowpaymentfee.com returns Helium (HNT) 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, crypto, and utility services. 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/HNT/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 given USDC's 6 decimals) to the provider's address on Base. No API keys, accounts, or rate limits are advertised — access is purely gated by micropayment.

Documentation beyond the landing page is extremely sparse. The /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical detail, request/response schemas, or usage examples. As a result, the exact request body format and response schema for this wallet balance endpoint are unknown and must be inferred from the URL path structure alone.

Quality

The x402 challenge is live and confirms pricing and settlement details, but there is virtually no documentation for this specific endpoint. Request/response schemas are entirely unknown; the example request body is inferred from the URL path. The /docs, /pricing, and /README pages are empty beyond a wallet-connect prompt.

Warnings

  • —No documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no technical content.
  • —Request body schema and response schema are unknown; the example request is purely inferred from the URL structure.
  • —The provider lists many endpoints across diverse categories (AI, analytics, finance, utilities) all at $0.02 — it is unclear whether all are fully functional or placeholders.
