Lido stETH APY data via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns Lido staking APY data through an x402-gated API at `https://lowpaymentfee.com/api/v1/defi/lido/apy`. Each call costs $0.02, paid in USDC on the Base network. The x402 challenge was confirmed live, returning a 402 with an `exact` payment scheme requiring 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) to the address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`.
The endpoint is part of a broader platform at lowpaymentfee.com that offers dozens of pay-per-call APIs spanning DeFi data, AI/ML inference, finance, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. The specific Lido APY endpoint is categorized under Finance & Web3, though it is not explicitly listed on the homepage (the homepage lists `/api/v1/finance/prices`, `/api/v1/finance/rates`, `/api/v1/crypto/quotes`, and `/api/v1/crypto/gas`). No OpenAPI schema, request/response examples, or detailed documentation were found in the crawl; the docs, pricing, and API pages all rendered only a "Connect wallet" prompt with no additional content.
Because there is no schema or sample response available, the exact shape of the returned APY data is unknown. Callers should expect a JSON response (the x402 challenge specifies `mimeType: application/json`) containing Lido staking yield information, but field names and structure must be discovered empirically.
