DYDX liquidity data via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides DeFi liquidity data for the DYDX token, accessible through the x402 payment protocol. It is hosted at lowpaymentfee.com, a platform offering a broad catalog of pay-per-call APIs spanning data analytics, AI/ML, finance/Web3, and infrastructure utilities. All endpoints on the platform share a uniform $0.02-per-request pricing model settled in USDC on the Base network.
The specific endpoint at `/api/v1/defi/DYDX/liquidity` accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, requiring a maximum payment of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02. Payment is made via the x402 `exact` scheme to the specified payTo address, with a 300-second timeout window. No API keys or rate limits are advertised; access is granted purely through per-request micropayment.
Documentation on the site is extremely thin — 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 is categorized under "Finance & Web3" on the provider's landing page, but the specific `/defi/DYDX/liquidity` path is not listed among the advertised endpoints, suggesting it may be an unlisted or newer addition. Without documentation on the expected request body or response format, consumers will need to experiment or contact the provider.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and this specific endpoint is not even listed on the provider's landing page. Essentially a stub listing.
