What it does

This endpoint at lowpaymentfee.com returns the wallet balance for the CAKE 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/CAKE/balance` accepts POST requests and is gated behind an x402 challenge requiring up to 20,000 base units of USDC (i.e., $0.02 given USDC's 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each call is paid individually at the time of request. The provider advertises a uniform $0.02/request price across all its endpoints.

Documentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (402 challenge captured), but the actual response format and required POST body fields are unknown. Users should expect to experiment or contact the provider for integration details.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no documentation, no OpenAPI spec, no response schema, and no example responses. The request body format is entirely inferred. The crawled pages beyond the landing page were empty stubs.

Warnings

  • No documentation available — /docs, /api, /pricing, and /README all returned only a wallet-connect prompt with no technical content.
  • No OpenAPI or schema definition found; request and response formats are unknown and must be guessed.
  • The example_request_json is inferred and may not match the actual expected payload.
  • Provider offers many endpoints across diverse categories (AI, analytics, finance, utilities) all at $0.02 — unclear whether all are fully implemented or functional.
