SUI liquidity data via x402 micropayment on Base — $0.02 per request, no API key needed.
What it does
This endpoint provides SUI liquidity data through the x402 payment protocol. It is part of a broader API platform at lowpaymentfee.com that offers DeFi, analytics, AI, and utility endpoints, all gated behind x402 micropayments settled in USDC on the Base network.
The specific endpoint `/api/v1/defi/SUI/liquidity` is categorized under Finance & Web3. Each request costs $0.02 (20,000 base units of USDC, which has 6 decimals). Payment is made per-call via the x402 `exact` scheme — no API keys, subscriptions, or rate limits are advertised. The endpoint accepts POST requests and returns JSON.
Documentation beyond the landing page is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the liquidity endpoint returns or what parameters it accepts. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know exactly what data is returned without making a paid request.

Quality
The endpoint is confirmed live with a valid x402 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages return only a wallet-connect prompt. The actual data returned by the endpoint is unknown, making this effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'
- —No request parameters or response schema documented anywhere
- —Exact data returned by the SUI liquidity endpoint is unknown without making a paid call
- —The provider hosts many generic-sounding endpoints (sentiment, geocoding, etc.) across diverse categories — quality and depth of each is unverifiable
