What it does

This endpoint at lowpaymentfee.com returns wallet balance information for TWT (Trust Wallet Token). It is part of a broader suite of pay-per-request APIs offered by the same provider, spanning data analytics, AI/ML inference, finance/Web3 data, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network.

The specific endpoint `/api/v1/wallet/TWT/balance` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, which uses 6 decimals), equating to $0.02 per request. The provider's landing page confirms a flat $0.02/request pricing model across all endpoints, with no API keys, no rate limits, and no minimum commitments required.

Documentation is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what parameters the endpoint accepts or what fields the response contains. The endpoint is live (returns a proper 402 challenge), but without documentation it is unclear what input the POST body should contain (e.g., a wallet address) or what the response structure looks like.

Quality

0.35/ 1.00

The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, documentation is essentially nonexistent — no OpenAPI spec, no request/response schema, no examples. The request body format and response structure are entirely inferred. This is effectively a stub listing.

Warnings

  • —No API documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no technical content.
  • —Request body schema is unknown; the example_request_json is speculative.
  • —Response schema is completely unknown; no example_response_json can be provided.
  • —The endpoint path suggests TWT-specific functionality but no details confirm what data is returned.
