Pay-per-call market quote for CVX token via x402 on Base, settled in USDC.
What it does
This endpoint provides a market quote for the CVX (Convex Finance) token. It is part of the lowpaymentfee.com platform, which offers a broad suite of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all gated via the x402 payment protocol on the Base network.
The specific endpoint `/api/v1/market/quote/CVX` accepts POST requests and returns JSON. Payment is settled in USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base) at a maximum cost of $0.02 per request (20,000 base units with 6 decimals). The x402 challenge was captured live and confirms the endpoint is operational. No API keys or rate limits are advertised; access is granted purely through per-call micropayment.
Documentation beyond the landing page is extremely thin — the /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint path suggests it returns a price quote for the CVX token, but the exact fields and format are unknown. The platform lists many other endpoints at the same $0.02 price point across finance, AI, and utility categories, but details on any of them are similarly sparse.
