What it does

This endpoint at lowpaymentfee.com provides SUI wallet balance lookups, paid per-request via the x402 protocol. The payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per call (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid payment proof.

The provider hosts a broader suite of APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced uniformly at $0.02 per request. This specific endpoint targets the SUI blockchain, returning wallet balance information. The x402 challenge confirms the endpoint is live, accepts POST requests, and outputs application/json.

Documentation on the site is minimal — the docs, pricing, and API pages all resolve to a "Connect wallet" prompt with no further technical detail. No OpenAPI schema, request/response examples, or parameter documentation were found. The exact request body format and response structure are undocumented.

The endpoint is confirmed live via a valid 402 challenge with clear pricing, but there is zero documentation on request parameters, response format, or error handling. The docs pages are empty stubs. Request/response examples are inferred, not sourced.

Warnings

  • —No API documentation available — docs/pricing/API pages all show only 'Connect wallet'
  • —Request body schema is completely undocumented; the example_request_json is speculative
  • —Response format is unknown — no sample responses found anywhere
  • —Provider appears to be a generic multi-API platform; unclear if SUI balance endpoint actually returns real blockchain data
