Get the current SUSHI token price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current price of the SUSHI token (SushiSwap's governance token) as a paid API call settled via the x402 protocol on the Base network. The payment is $0.02 per request in USDC, with no API keys, rate limits, or subscriptions required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The endpoint is part of a broader suite of APIs offered at lowpaymentfee.com, which spans data analytics, AI/ML inference, finance/Web3 market data, and utility services — all priced at $0.02 per call. This specific endpoint lives under the Finance & Web3 category and is designed for agents or applications that need on-demand token pricing without traditional API key management. The x402 challenge confirms the endpoint is live, accepts POST requests, and settles payments to a specified address on Base using USDC (contract 0x8335…2913).
Documentation beyond the landing page is minimal — the /docs, /pricing, and /README pages all resolve to a wallet-connect stub with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The actual data source for SUSHI pricing is not disclosed.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no documented request/response schema, no example payloads, and the docs pages are empty stubs. The data source for SUSHI pricing is undisclosed. This is effectively a stub listing.
