PancakeSwap APY data via x402 micropayment — $0.02/request on Base network
What it does
This endpoint returns PancakeSwap APY (Annual Percentage Yield) data through the x402 payment protocol. It is hosted on lowpaymentfee.com, a platform offering a variety of pay-per-call APIs spanning DeFi, analytics, AI, finance, and utility categories. Each request costs $0.02 in USDC on the Base network, with no API keys, rate limits, or subscriptions required.
The specific endpoint at `/api/v1/defi/pancakeswap/apy` is a POST endpoint that returns JSON. Payment is handled via the x402 protocol: callers include an `X-PAYMENT` header with a signed payment of up to 20,000 base units of USDC (i.e., $0.02) to the provider's address on Base. The endpoint was confirmed live, returning a proper 402 challenge with x402 version 1.
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 spec, no request/response schema, and no example payloads available. The endpoint's exact input parameters and response structure are unknown and must be discovered by calling it. This limits confidence in what data is returned and how to structure requests.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it exists and accepts payment. However, there is no OpenAPI spec, no documentation beyond a wallet-connect prompt, no request/response schema, and no examples. The endpoint's actual behavior and output format are entirely unknown.

- —No OpenAPI or request/response schema provided; input parameters and output format are unknown
- —Endpoint description is generic ('Premium API Access') and does not describe the data returned
- —Cannot verify what PancakeSwap data is actually returned without making a paid request
