OCEAN token liquidity data via x402 micropayment on Base network for $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for the OCEAN token. It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network at $0.02 per request.
The specific endpoint `/api/v1/defi/OCEAN/liquidity` accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, requiring a payment of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. No API keys or rate limits are advertised; access is gated purely by the x402 micropayment. The payment recipient address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a max timeout of 300 seconds.
Documentation is extremely sparse. The landing page lists available API categories and pricing, but the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the OCEAN liquidity response contains or what parameters the POST body accepts. The endpoint appears functional based on the 402 challenge, but the lack of documentation makes it difficult to use without experimentation.

Quality
The x402 challenge confirms the endpoint is live and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages render only 'Connect wallet' with no usable content. The OCEAN liquidity endpoint itself is not even listed on the landing page, making its existence inferrable only from the URL pattern. This is effectively a stub listing.
