What it does

This endpoint at lowpaymentfee.com provides Uniswap APY (annual percentage yield) data through the x402 payment protocol. It is part of a broader suite of Finance & Web3 APIs offered by the same provider, which also includes price feeds, exchange rates, token quotes, and gas estimates.

The endpoint accepts POST requests and is gated by an x402 payment challenge settled in USDC on the Base network. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. No API keys, rate limits, or upfront commitments are required — each request is paid for individually via the x402 header.

Documentation is extremely sparse. The provider's 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 shape the APY data takes. The endpoint is confirmed live (returns a proper 402 challenge), but without documentation it is difficult to know the exact request body format or response structure. Users should expect to experiment or contact the provider for integration details.

Quality

0.35/ 1.00

The endpoint is confirmed live with a valid x402 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages return only a wallet-connect prompt. The listing is essentially a stub with pricing info.

Warnings

  • —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no technical content.
  • —No OpenAPI or JSON schema for request or response bodies.
  • —No example requests or responses available; request body format is unknown.
  • —The provider hosts many generic-sounding endpoints across unrelated domains (AI, geocoding, finance) — quality and depth of each is unverified.
