Query SushiSwap DeFi positions via x402 micropayment on Base for $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to SushiSwap DeFi position data through the x402 payment protocol. It accepts POST requests and charges $0.02 per call (20,000 base units of USDC on the Base network, where USDC has 6 decimals). No API keys or accounts are required — callers pay per request using an X-PAYMENT header with a valid x402 payment proof.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and utility services, all priced at $0.02 per request. The specific endpoint `/api/v1/defi/sushiswap/positions` is focused on SushiSwap liquidity positions, though the exact request schema and response fields are not documented in the available crawl material. The platform advertises no rate limits, no minimums, and instant access.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response examples, and no description of what parameters the endpoint accepts or what fields it returns. Prospective users should expect to experiment with the endpoint to discover its capabilities.

Quality
The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples. The endpoint's actual functionality is entirely inferred from its URL path.
