MakerDAO APY data via x402 micropayment on Base — $0.02 per request, no API key needed.
What it does
This endpoint returns MakerDAO APY (annual percentage yield) data from the DeFi protocol, accessible at `https://lowpaymentfee.com/api/v1/defi/makerdao/apy`. It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com, covering data analytics, AI/ML inference, finance/Web3, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.
Pricing is $0.02 per request (the x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC, which has 6 decimals, equaling $0.02). There are no API keys, no rate limits, and no minimum commitments — callers simply attach an x402 payment header to each request. The endpoint accepts POST requests and returns `application/json` responses.
Note that while the endpoint is confirmed live (returns a valid 402 challenge), the specific MakerDAO APY endpoint (`/api/v1/defi/makerdao/apy`) is not listed on the provider's landing page among the advertised API catalog. Documentation beyond the landing page is effectively empty (all doc/pricing/README pages only show a "Connect wallet" prompt). The exact response schema and request body format are not documented, so the output structure must be inferred from the endpoint name — it likely returns current MakerDAO savings rate or vault APY figures.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no documented request/response format, no examples, and the specific MakerDAO APY endpoint isn't even listed on the provider's own landing page. All documentation pages beyond the homepage are empty stubs.
Warnings
- —The /api/v1/defi/makerdao/apy endpoint is not listed among the provider's advertised APIs on the landing page — it may be unlisted or experimental.
- —No response schema or example output is available; the exact data returned is unknown.
- —All documentation, pricing, and README pages are empty (only show 'Connect wallet'), so there is no official usage guide.
